  • Toby Ord on existential risk, Donald Trump, and thinking in probabilities

    Oxford philosopher Toby Ord spent the early part of his career spearheading the effective altruism movement, founding Giving What We Can, and focusing his attention primarily on issue areas like global public health and extreme poverty. Ord’s new book The Precipice is about something entirely different: the biggest existential risks to the future of humanity. In it, he predicts that humanity has approximately a 1 in 6 chance of going completely extinct by the end of the 21st century.

    Wait! Stay with me!

    The coronavirus pandemic is a reminder that tail risk is real. We always knew a zoological respiratory virus could become a global pandemic. But, collectively, we didn’t want to think about it, and so we didn’t. The result is the reality we live in now. 

    But for all the current moment’s horror, there are worse risks than coronavirus out there. One silver lining of the current crisis might be that it gets us to take them seriously, and avert them before they become unstoppable. That’s what Ord’s book is about, and it is, in a strange way, a comfort. 

    This, then, is a conversation about the risks that threaten humanity’s future, and what we can do about them. It’s a conversation about thinking in probabilities, about the ethics of taking future human lives seriously, about how we weigh the risks we don’t yet understand. And it’s a conversation, too, about something I’ve been dwelling on watching President Trump choose to ratchet up tensions with China amidst a pandemic: Is Trump himself an existential risk, or at least an existential risk factor?

  • The Story of Schizophrenia

    AI transcript
    0:00:05 Hi and welcome to the A16Z podcast. I’m Hannah and in this episode we talk all about the remarkable
    0:00:12 story of one American family, the Galvans, Mimi, Don, their 10 sons, and two girls,
    0:00:18 out of whom six sons were afflicted with schizophrenia, following them from the 1950s to today.
    0:00:22 Robert Kolker, author of the book and previous author of “Lost Girls,” writes,
    0:00:29 “They lived through the eras of institutionalization and shock therapy, the debates between psychotherapy
    0:00:34 versus medication, the needle in a haystack, search for genetic markers for the disease,
    0:00:38 and the profound disagreements about the cause and origin of the illness itself.”
    0:00:44 And because of that, this story is really more than just a portrait of one family. It’s a portrait
    0:00:49 of how we have struggled to understand this mental illness, the biology of it, the drivers,
    0:00:54 the behaviors and pathology, the genomics of it, and of course the search for treatments that might
    0:01:00 help. Also joining Robert Kolker and myself for this conversation is Stefan McDonough, Executive
    0:01:05 Director of Genetics at Pfizer World R&D, who is one of the genetic researchers who worked closely
    0:01:11 with the Galvans. We start by talking about our attempts to understand and treat schizophrenia
    0:01:17 from Freud to lobotomies to the entrance of Thorzine onto the scene, where that understanding
    0:01:22 of the disease finally began to shift, especially with new technologies and the advent of the human
    0:01:28 genome project, and where we are today in our understanding of the disease, how to treat it,
    0:01:33 and where our next big break might come from. What really struck me about this book was that
    0:01:41 it was this huge story, not just about one family and this particular disease of schizophrenia,
    0:01:46 but also kind of a portrait of our entire effort to understand mental illness period,
    0:01:53 and not just how we understand it, but how we experience it and how we try to treat it.
    0:01:59 Let’s go back a little bit and talk about schizophrenia itself. I’d love to hear where
    0:02:05 you think our modern understanding of the disease really began. You describe a key moment in 1903
    0:02:11 where we shift from thinking of it as a religious ailment into something else, or where would
    0:02:16 you begin that story? That’s around the time of the dawn of psychiatry as we understand it today.
    0:02:21 Obviously, there are glimmers beforehand of people believing that mental illness is physical and
    0:02:27 not spiritual or religious, but by the turn of the century, there was an entire field emerging,
    0:02:31 and there was a nature-nurture debate over what schizophrenia was that really,
    0:02:37 in many ways, continues today in a different form. Back then, the debate was between Freud,
    0:02:43 who believed that therapy could cure schizophrenia, that schizophrenia was something that happened in
    0:02:48 the nurture side of things, something that happened in your childhood caused it, perhaps bad parenting.
    0:02:54 On the other side were a lot of other psychiatrists, including the ones who named schizophrenia,
    0:02:59 who believed it had some sort of physical property, but could never put their finger
    0:03:05 on what it was. Into this debate come the Galvans, who by the 1950s and ’60s are starting to become
    0:03:10 mentally ill at a time where most psychotherapy believes it’s the parent’s fault, and medical
    0:03:16 psychiatry is sure that drugs can hit whatever is happening genetically, but they really have no
    0:03:21 clue how those drugs work or what genes are really at play, and this continues for decades.
    0:03:27 The story of the family starts in the 1950s, but you describe some developments before you
    0:03:34 get to this with Dr. Frome Reichman and Gregory Bateson and a couple of other characters that,
    0:03:39 to me, felt like kind of key points as our understanding of the disease was developing.
    0:03:45 In 1948, Frita Frome Reichman, who was a psychoanalyst then living in America, came up with a term
    0:03:51 called the Schizophrenogenic Mother, which she believed was a certain type of mother or father,
    0:03:58 in some cases, who was so bad at parenting, was so torturous in the way that they dealt with their
    0:04:04 children that the child then would somehow create their own imaginary reality in order to escape from
    0:04:11 that parent and become schizophrenic. That was the split. The split was from internal to external.
    0:04:15 Exactly. Sometimes people think schizophrenia means split personality,
    0:04:20 but it really never did, and it’s really a split between your perceptions of reality and of what’s
    0:04:26 happening inside you. Frita Frome Reichman was doing this at a time where lots of psychoanalysts
    0:04:32 were blaming mom and dad for lots of things. Of course, by 1960, you have the movie Psycho,
    0:04:36 the greatest homicidal maniac in all of cinema. His problem is his mother, and everybody says,
    0:04:42 “Oh, yes, that must be what happened.” It seems strange now, but when you think about it back then,
    0:04:48 people like Frita Frome Reichman and Gregory Bates, they were doing battle against eugenics
    0:04:52 at the time of modern feeling that you could breed out schizophrenia and that you should
    0:04:59 sterilize or even euthanize mentally ill people. They were also doing battle with people who were
    0:05:04 committing lobotomies and insulin shock therapy and electroshock therapy. They were doing battle
    0:05:09 with a medical field that was treating schizophrenic people as subhuman. They felt like they were on
    0:05:15 the side of the angels. It was really interesting to me that the kind of duality from Reichman,
    0:05:21 her position, on the one hand, having more compassion than anyone had ever really had before
    0:05:25 for the people suffering from this disease, but on the other hand, having so little compassion.
    0:05:29 For the mothers, it was just a very interesting split there.
    0:05:35 Yes, indeed. I think she and a lot of other therapists of her generation were threatened
    0:05:40 by changes in society. Women are working after the war. The family unit is being threatened
    0:05:46 in some way. The sexual revolution is about to happen. Any major changes in society then began
    0:05:51 to be attached to the idea of mental illness until the researchers who went after the Galvin
    0:05:57 family who came up in the late ’60s and early ’70s at a time when a lot of established psychiatry
    0:06:02 was telling them still that parents were the problem and that working mothers in particular
    0:06:07 were the problem. One of the things that really struck me, Bob, was you start in a really interesting
    0:06:17 place. You begin with a story of training a falcon and Mimi, you call her a refined daughter of
    0:06:23 Texas aristocracy by way of New York, clutching a live bird in one hand and a needle and thread
    0:06:30 in the other, preparing to sew the bird’s eyelids shut. Can you tell me why did you start this huge
    0:06:36 story about mental illness with this one incredibly vivid and surprising moment?
    0:06:43 This took place maybe a week or two after Mimi and her children moved to Colorado Springs in
    0:06:48 the early ’50s to join their husband who had just moved there for the Air Force. The whole thing was
    0:06:53 unfamiliar to her. It was out of her comfort zone and then to be thrust into this situation where
    0:07:00 she was suddenly getting into falconry and having to sew eyelids shut, this was as foreign as it
    0:07:05 came to her. The point of the story really is that she accomplishes it. She winds up training and
    0:07:12 disciplining the falcon and it winds up becoming almost an allegory for how she approaches the rest
    0:07:16 of her life, including the raising of children. She thinks if she tries hard enough, does all the
    0:07:21 right things and does them all in the right way with discipline and pressure, she will get the
    0:07:26 results she desires. And we all know that with children that isn’t exactly true, but in the
    0:07:34 Galvin family’s case, it’s tragically true. 12 children, six of whom had acute mental illness.
    0:07:41 And before we get into this particular family and how they dealt with this, I just want to talk
    0:07:46 also a little bit about up until that moment, the different treatments that had matched up to our
    0:07:51 understanding of the disease that we had tried. You mentioned insulin shock in the 1930s, lobotomizing
    0:07:56 attempts and things like that. Can you kind of map out those early therapeutic attempts?
    0:08:01 Well, lobotomy is about severing nerves in your frontal lobes. It’s an extreme measure and I
    0:08:07 think most people would consider it barbaric now, but it was intended to impair you just enough
    0:08:11 so that you would stop hurting yourself mentally. That seemed to be the justification for it at the
    0:08:16 time. But the other procedures that you mentioned, things like electroshock therapy and insulin
    0:08:22 shock therapy all sort of operate on the same principle, which is to somehow induce enough
    0:08:29 stimulation, enough of a seizure, even almost a medical coma, so that you shock the patient into
    0:08:35 focusing and not being so distracted or drawn away by whatever is going on with their brain chemistry.
    0:08:41 And sometimes it would seem to work at least temporarily, and other times they would decide
    0:08:46 that the person needed to be shocked every day. So then in the 1950s, a major development on the
    0:08:51 drug side, you talk about the entrance of thorazine onto the scene, which dominates the next
    0:08:55 second half of the century and still has a huge legacy in how we handle this
    0:09:03 mental illness. Can you talk about what brought thorazine in and what that moment was like?
    0:09:08 Like a lot of pharmaceutical advances, it happened sort of sideways or by accident.
    0:09:12 There was a French surgeon who was trying to come up with a battlefield anesthetic,
    0:09:20 and he did some combining of traditional anesthetic and narcotics and found that the people he was
    0:09:26 testing it on, it almost induced a happy coma on them the way that he described it. This drug
    0:09:32 eventually was thorazine and even now, really, thorazine is the great advancement pharmacologically
    0:09:38 for schizophrenia and still is. And then there’s an atypical version or variety of a psychotropic
    0:09:44 drug called chlozapine. And my understanding is that those two drugs really are the coke and pepsi
    0:09:50 of this field and that any drug out there is sort of a derivation of one or the two.
    0:09:56 There are people who were in such extreme condition and harming themselves so much
    0:10:00 that certainly drugs like this could be helpful to them to keep them alive.
    0:10:05 But I think the other sad fact is that they aren’t cures and that it’s been decades now
    0:10:10 and there really has been no revolutionary drug for schizophrenia since the 1950s and 60s.
    0:10:14 The best clue to actually understanding how to attack a disease is have something that cures
    0:10:19 the disease, especially something like schizophrenia where the etiology, we may be starting to
    0:10:24 understand some of the underpinnings with it, but people don’t come to us at birth and say,
    0:10:29 “I’m going to have schizophrenia. Please modify me in some way.” We wait until the symptoms develop
    0:10:35 and so exactly as Bob said, it was the cornerstone advance in the field to find a therapy that you
    0:10:41 can take as a pill that did in some ways make some patients better. Then you can just simply
    0:10:46 reverse engineer that therapy and try to find out on a molecular level what is it doing.
    0:10:50 And then that leads to understanding of disease, to dopamine receptors, to serotonin receptors,
    0:10:56 and so on. So let’s go back now to that moment in the 1950s which is basically where the Galvan
    0:11:03 story starts as well. By the 1960s, the oldest of the 12 Galvan children were starting to go
    0:11:08 off to college and as we know schizophrenia’s onset is quite often in late adolescence. And so
    0:11:13 the oldest son, Donald, the star of the family, the football star, the guy who dated the general’s
    0:11:20 daughter and who was a master falconer and repeller on the cliffs of central Colorado,
    0:11:25 he had really had secretly felt quite alienated from mainstream life and really was struggling
    0:11:30 in many ways privately and that struggle went public by the middle of college. He ran into a
    0:11:36 bonfire and didn’t know why, he tortured a cat and killed it and didn’t know why. He ended up in
    0:11:42 student health services for many different reasons until finally psychiatrists got involved. And this
    0:11:49 was a panic moment for Don and Mimi Galvan, the parents, because they knew that first of all they
    0:11:55 would be judged because at the time if your child had a psychiatric problem it obviously must have
    0:12:01 been the parent’s fault. And so they went shopping for a good opinion because back then really what
    0:12:06 illness you had psychiatrically really depended on what doctor you visited. Some would say give him
    0:12:12 Thorazine, others would say give him a lobotomy. So they went and they found a doctor who recommended
    0:12:17 he could go back to college and that he would just grow out of it. And then he got worse and worse
    0:12:24 and until finally he had a moment of violence with his young wife, that was it for him. He went off to
    0:12:28 the state mental institution for a few weeks and then spent the rest of his life
    0:12:34 really at home with Don and Mimi, with his parents, almost as a revolving door between the state
    0:12:40 institutions and home. It struck me that every story kind of showed the different lenses that
    0:12:47 we’ve used to try and understand this disease. Each had some of these common traits and some
    0:12:54 wild discrepancies and differences. A lot of the stories began with we sort of always knew,
    0:12:59 but some of them became completely out of left field. And then some of them even seemed like
    0:13:05 they come from a cultural moment like Michael who goes to live on the farm in the 1960s.
    0:13:09 That’s right. Michael’s sort of a hippie and he is rebelling and then that gets confused with
    0:13:16 mental illness for a time. He insists that he is not mentally ill. Peter was very, very
    0:13:21 oppositional as a kid said no all the time and then he had psychotic breaks. So you could say
    0:13:26 they saw that coming. Joseph had a detachment from reality, it seemed now and then. And so
    0:13:31 everybody was sort of waiting for him to finally have a psychotic break and he did in the early
    0:13:36 80s. But then there were surprises. Matt, who was a talented ceramic artist suddenly one day out of
    0:13:43 nowhere, smashes something that he made and strips naked in a friend’s house and suddenly
    0:13:50 he becomes medicalized as well. So it’s interesting how some seem explainable and others do not.
    0:13:55 At the same time as we’re hearing this story of how our understanding of the disease changed and how
    0:14:02 this one family that manifested so many of those efforts to understand and manage it,
    0:14:08 it’s also a story of technology, the developing technology that we have to understand biology
    0:14:13 and to understand our brain. Another key moment was when suddenly we start being able to see the
    0:14:21 brain through scans in the 70s. Can we go to how this story evolved when that kind of technology
    0:14:29 came on the scene? Yes, by the 70s researchers were able to have some glimpses into the brain
    0:14:35 thanks to technology, thanks to MRIs and PET scans and CT scans and the like. And with the
    0:14:41 sequencing of DNA, it became possible to think about being able to actually study the genetics of
    0:14:46 any sort of population of people with any sort of illness or disease. Technology drives biology
    0:14:50 across multiple areas. I see that story again and again in whatever field I’m in. You look at the
    0:14:55 beginning, the first MRIs, those could only be structure. This might tell you is the structure
    0:14:59 of the brain different, but it doesn’t tell you how it functions. It feels like it’s a story about
    0:15:04 a family, but it’s also really a story about kind of modern genomics and going from understanding
    0:15:11 something as a inherited disease in some way to dialing into a way different level of understanding
    0:15:17 about genetic information. So what was the genomic story of what we understood of schizophrenia
    0:15:23 pre-Galvin’s? Why was the family such a turning point in the context of the human genome project?
    0:15:28 And then what did we learn from them? I write about Robert Friedman, who’s at the University
    0:15:34 of Colorado Hospital, and Lynn Delisi, who is at the National Institute of Mental Health.
    0:15:38 Lynn’s story really intersects with Stefan’s, my fellow guest on this show.
    0:15:44 And before she met Stefan, she was a pioneer in studying families like the Galvans. And the
    0:15:49 Galvans were the biggest family she ever found in those early years. And she was convinced that
    0:15:54 families were the best way to take a look at this illness because you weren’t searching for a needle
    0:15:59 in a haystack. You had a much smaller haystack to look through. They were a closed petri dish of
    0:16:04 shared genetic data with a lot of incidents of schizophrenia. Multiplex families like the Galvans,
    0:16:09 with lots of schizophrenia in them, have something to teach us. And she amassed the largest collection
    0:16:14 of family DNA for this purpose. But there came a time in the ’90s when the human genome project
    0:16:19 was underway, when everyone thought that once the genome was sequenced, they’d be able to do
    0:16:25 entire population-wide studies. And that anyone with schizophrenia or with any other complex
    0:16:31 genetic disorder would sort of stick out like a sore thumb, you would find the smoking-gun gene,
    0:16:38 or genes. And then you’d have a target to medicate with a drug. And bingo, we’d all be cured by the
    0:16:45 time dinner came. But the problem is that with complex conditions like schizophrenia, it only
    0:16:51 complicated things so much more. They found one genetic irregularity for schizophrenia, and then
    0:16:57 another, and then another, and then another. Until now, there are far over 100 genetic issues.
    0:17:04 Unfortunately, each one of these irregularities contributes just a fraction of a percentage of
    0:17:09 the probability that you might get the illness. And so it winds up being meaningless. It strikes
    0:17:15 me as just as fluid and complicated and long a list as the list of symptoms that over the last
    0:17:21 century have been associated with the disease, the manifestations of it. Exactly. And it’s not
    0:17:27 helpful clinically. It might be helpful for future research, but at the moment, it just makes the
    0:17:33 mystery more mysterious, which is what makes it so interesting that when Stefan recognized that
    0:17:38 families might have something to offer and wondered, hmm, who out there has been studying
    0:17:43 families? And lo and behold, there was a woman who had been doing it all this time, and the two of
    0:17:47 them teamed up. Stefan, can you talk about what it was like to enter on the scene in that moment and
    0:17:54 what the genomic aha was for you there? Yeah, the technology had not been there to really analyze
    0:17:59 the families that Lynn collected. She collected them so much before the technology was available to
    0:18:04 really look in fine depth at the genome and find, is there something different? Back when I was in
    0:18:10 grad school studying genetics, it was mustard weed and fruit flies and sort of model organisms.
    0:18:15 When the genomic revolution came along, so much computational power came to be developed. The
    0:18:21 technology just kept developing to be able to sequence entire genomes rapidly and inexpensively,
    0:18:26 comparatively inexpensively. People sort of thought with a disorder that is so strongly
    0:18:33 heritable as schizophrenia, there must be something there. And again, what was turned up in surveys
    0:18:38 of tens of thousands of schizophrenia, looking at all the genetic variants they carried versus tens
    0:18:44 of thousands of people matched controls as best they could, say for ethnicity and other factors.
    0:18:49 No question there are differences. Those have led to some hypotheses, like sort of a general
    0:18:55 overall role of the immune system. But in terms of discovering what is the driver
    0:19:01 for a disease like schizophrenia, it just simply didn’t work that way. And we still don’t understand
    0:19:07 why. Where are we starting to make progress there and understanding kind of the biology
    0:19:13 and the drivers and potentially how to treat them? You talked about looking at when a drug
    0:19:18 like Thorazine works and trying to work backwards from that to understand more of the biology.
    0:19:23 Are we still there or does our understanding of the underlying genomics shifted a bit?
    0:19:30 Shifted a bit. I think we’ve gone from a picture of, again, as Bob said, evil spirits or dreams
    0:19:36 or some environmental influence or a mother to sort of a holistic picture of the brain whereby
    0:19:42 following Thorazine, we would say, okay, well, dopamine is dysregulated or glutamate is dysregulated
    0:19:46 and these are chemicals neurotransmitters for how nerve cells communicate with one another.
    0:19:53 Now we’re verging towards a sort of cellular synaptic view. Another of the technology that
    0:19:59 developed probably in the 80s and especially 1990s was the ability to really look in very,
    0:20:05 very fine detail in sort of millisecond scale resolution at how nerves communicate with one
    0:20:10 another. You can stick an electrode on one nerve and stick an electrode on the other and really
    0:20:15 record how they’re communicating. So this is, I think, how our overall picture of biology is
    0:20:22 evolving into as to what it means how we cure the disease. Classic analogy, in order to fix a
    0:20:27 broken TV set, you have to know what makes it work in the first place. And we’re still not there,
    0:20:32 but we’re getting closer. What is the technology that’s coming onto the scene now that is changing
    0:20:38 our potential understanding moving forward? I think one of the areas that’s exciting now
    0:20:43 is you can actually take a skin cell from somebody and treat it with appropriate biological factors
    0:20:49 and it will differentiate into something that to first approximation might be a human neuron.
    0:20:54 I haven’t seen therapies come out of it yet. In fact, it may be another blind alley as with
    0:21:00 all areas of research. But there is the hope that if you take a skin cell or a group of skin cells
    0:21:06 from somebody with schizophrenia, perhaps that mutation is genetic. Perhaps that mutation then
    0:21:12 is still carried in the skin cells and their nerves might look different. So this is a possible angle.
    0:21:16 It’s a bit of a risky one for many reasons. You never know if you’re actually dealing with a neuron.
    0:21:20 What do you mean by it’s hard to even know if you have a neuron?
    0:21:26 Well, you’ve taken a fibroblast, a skin cell, you’ve treated it with appropriate factors and
    0:21:31 certainly it elongates, it starts sending out processes and if you can stick an electrode
    0:21:36 in it, you can see that it’s electrically active. Does that mean that it really is close enough to
    0:21:41 a human neuron in a human brain that has developed through its entire life, through the entire life
    0:21:45 of the individual and has been exposed to all the different environmental influences?
    0:21:46 Right.
    0:21:51 The question isn’t, is one thing like the other? They are like on some level, unlike on others.
    0:21:56 Is it enough alike that you could actually try to turn a therapeutic on it and try to do your
    0:22:01 modification now you’ve got sort of a disease in a dish? And that’s an open question.
    0:22:06 Bob, where would you see the Galvanes their story if it was unfolding today? Can you talk a little
    0:22:12 bit about how it kind of mapped to where the understanding is, where their story ended?
    0:22:16 Well, the two separate teams who studied the Galvanes, each have come forward with some really
    0:22:23 interesting advances, both of which offer a lot of hope. Lynn, Delisi, and Stefan sequenced the
    0:22:29 genome of the Galvan family and found one irregularity in a gene called shank 2. This is not a
    0:22:34 silver bullet or a smoking gun. It’s not like the shank 2 gene is the ketoschizophrenia. However,
    0:22:41 assuming that it is the player that really did its trick on the Galvan family, it is a gene that’s
    0:22:45 highly related to brain function and could, with further study, point the way to understanding
    0:22:51 how schizophrenia works, how that TV set works, as Stefan had said before. And so that’s exciting.
    0:22:57 And more broadly, in terms of drug discovery, families like the Galvanes can be almost sort
    0:23:03 of test kitchens. You can look at how their genetic code might interact with certain potential
    0:23:08 therapies and see perhaps how it might go with the broader population. Then with that second
    0:23:14 set of researchers led by Robert Friedman over in the University of Colorado, he, with help from
    0:23:19 the Galvanes and other families, identified another genetic area called churn a seven. And churn a
    0:23:25 seven is related to the vulnerability theory of schizophrenia, which is that perhaps one is
    0:23:31 oversensitive or has a sensitivity issue to stimuli. It looks at schizophrenia as a developmental
    0:23:37 disease, one that really begins in utero even though it manifests itself much later. And over the
    0:23:43 years, he struggled to find a way to perhaps make the churn a seven area more healthy or more resilient
    0:23:51 and less vulnerable. And he has a hypothesis that there actually is a safe nutritional supplement,
    0:23:58 choline can strengthen brain health generally of the unborn child, but also perhaps cross your
    0:24:05 finger 16 times, perhaps many years from now prove to make the children more resilient,
    0:24:11 less vulnerable to psychosis. And they’re doing longitudinal studies right now using choline,
    0:24:15 and if it shows any promise at all, he has the Galvanes and other families like them to thank.
    0:24:20 Stephanie, it would be very interesting to hear from your side of the kind of story of the pharma
    0:24:26 industry attempt to manage this as well. Where would you see those attempts after Thorzine?
    0:24:30 Then where did we go next? And what was the sort of industry response? Where are we today
    0:24:34 in the possibility? Yeah, there was a quite productive age where drugs like Cypraxa were
    0:24:39 developed, where we’re looking for simply animal behaviors that were related to schizophrenia.
    0:24:44 And here is where having sort of a toolkit is quite valuable in a sense, because if you know,
    0:24:49 for example, if there’s some odd behavior that an animal is showing that Thorzine mitigates,
    0:24:53 then without even knowing the receptors involved, perhaps you can test drugs and animals
    0:24:58 for other drugs that mitigate those behaviors and perhaps don’t have side effects.
    0:25:03 So the problem, of course, is that rats don’t get schizophrenia. They don’t even have sort of the
    0:25:07 massive cortical structures in the folding that we think is where the
    0:25:10 higher processes that are affected in schizophrenia reside.
    0:25:14 So to your point about cells in a dish, I mean, it’s really a problem of models, right?
    0:25:19 It’s a problem of models. How do you, before doing a clinical trial in humans,
    0:25:25 how do you get confidence that your drug is going to work? And I think in the 1990s, there were
    0:25:29 a number of very good efforts based on sort of synaptic studies. People have known, again,
    0:25:34 going back to some of the early pharmacology that dopamine was involved, that glutamate was involved.
    0:25:39 Now we started to identify with the human genome project and just molecular cloning in general.
    0:25:45 We started to uncover what the molecules are that regulate glutamate and regulate dopamine.
    0:25:50 And a number of clinical trials were done on these as well.
    0:25:54 What still does stymie the field today is, if you take the overall disease,
    0:25:59 what is your model? What do you test it on that gives you confidence that you can test
    0:26:01 this safely in humans and that it will have some effect?
    0:26:07 How do people even do that? I mean, are there any other tools before you begin clinical trials in
    0:26:11 humans when there’s a disease that really doesn’t present anywhere else outside of humans?
    0:26:16 Schizophrenia is a tough one. It’s very tough. Now nothing is easy, but for example,
    0:26:21 tumors do grow in animals. And you can implant a patient-derived x-plant,
    0:26:25 a patient-derived tumor into an animal, and perhaps test therapies there.
    0:26:31 Or you do have cancer cell lines, tumors will actually, cell lines will actually grow in a dish.
    0:26:35 And so something that kills those could reasonably be called to be acting on the tumor.
    0:26:38 And we simply don’t have that equivalent for schizophrenia.
    0:26:43 So what was the next moment where there was sort of a something that seemed
    0:26:47 on the pharmacology side like a real viable treatment that we were,
    0:26:50 you know, that people were getting excited about? And where are we now?
    0:26:54 People were excited about metapotropic glutamate receptors. That’s a particular type,
    0:26:58 a subtype of glutamate, which is the main excitatory neurotransmitter in the nervous
    0:27:03 system in humans. People were excited about sort of finer manipulations of dopamine receptors.
    0:27:07 And again, by reverse engineering some of the atypical antipsychotics,
    0:27:11 you could find out that serotonin receptors also had involvement.
    0:27:15 Now each of these is going to be a broad family of many, many genes.
    0:27:22 So can you do more finer manipulations of these? Not every advance in drug therapy has to be a
    0:27:29 totally new mechanism. Schizophrenics and other CNS disorders are famous for going off their medications.
    0:27:34 So if you can perhaps make a medication that just simply lasts longer
    0:27:39 and can be given maybe every month or even at less duration under a doctor’s supervision,
    0:27:43 that’s a significant medical advance. And this is an engineering challenge.
    0:27:49 I started life as an engineer and drug discovery is really biological engineering.
    0:27:53 I’m not saying it’s easy, but we do know how to make drugs last longer in the body.
    0:27:56 There’s a very interesting story in there with Nicotine.
    0:28:02 The receptor that Robert Friedman in Colorado had identified with help from the Galvin family
    0:28:07 and other families like them was a nicotinic receptor. And strictly speaking,
    0:28:13 that’s a receptor that when medicated might actually help with focus and concentration.
    0:28:18 I mean, there’s a stereotype of schizophrenic patients actually getting some relief from chain
    0:28:23 smoking because it focuses their mind. And there’s a hypothesis related to nicotine,
    0:28:28 and there was for a time that if you could somehow drug this receptor a little bit to help it along,
    0:28:34 that perhaps this would prevent delusions or even prevent psychotic breaks.
    0:28:39 And Robert Friedman did try for a while to work on a drug for that, and he reports anecdotal
    0:28:45 excellent results from many patients. But it was a drug that you had to take several times a day,
    0:28:50 and that was something that the pharmaceutical companies couldn’t bring through trials to make
    0:28:56 into a once a day drug. So it went away. So he decided to go after the nicotinic receptor
    0:29:04 in utero through choline. Especially in the 1990s, there was a lot of companies and a lot of academic
    0:29:10 researchers investigating nicotine and nicotinic receptors. And again, there did seem to be a
    0:29:15 clear link to schizophrenia. Perhaps schizophrenics are self-medicating by smoking. If so, perhaps
    0:29:21 you can make sort of a subtype of nicotine that gives you some benefit or perhaps even some more
    0:29:26 benefit. And again, as Bob said, that perhaps lasts long enough in the body to be practical to
    0:29:32 be taken as a drug. So in this case, there was a biological challenge there, no question. But it
    0:29:39 became also an engineering challenge, as all drug discovery does. Nicotine is quite a non-selective
    0:29:43 molecule. Well, everything it hits is called a nicotinic receptor. But your body has something
    0:29:49 like 14, 15 genes for individual subunits that together come together to form a receptor for
    0:29:54 nicotine. And they all mix and match in very unpredictable ways and ways that still are not
    0:30:01 well known. So the challenge was quite formidable. People did go ahead for technical reasons.
    0:30:06 It turned out to be easy to make sort of a subform of nicotine that would only hit Alpha 7
    0:30:12 receptors. Not easy, but not impossible either. People had good reason to think that this might
    0:30:18 work. No question, it was a huge downer for patients, for the field, for everybody when
    0:30:23 this entire class of drugs just sort of didn’t seem to come to nothing. But we learned.
    0:30:30 And the negative result often is just as informative as the positive result we do learn.
    0:30:37 Can I ask how incentivized is the sort of pharmaceutical industry right now to find
    0:30:43 other alternatives to things like the class of drugs that, you know, Thorazine and some others
    0:30:48 that you’ve mentioned? I mean, because those do work to some extent, yes?
    0:30:53 To some extent. So I’m not a clinician. About 50% of the patients respond well to
    0:30:59 atypical antipsychotics. But this doesn’t touch sort of the cognitive and the emotional problems.
    0:31:04 And one of the things, one of the many things I’m grateful to Lynn for was really taking me
    0:31:10 to visit her patients so that I could really see there’s no question something is wrong,
    0:31:16 just sort of a very emotionless, flat affect. The cognition is fine. Clearly,
    0:31:21 these people are very articulate. They’re very bright in many cases. But something’s
    0:31:27 badly wrong. So to your question, what is the incentive for pharmaceutical companies?
    0:31:32 It’s a huge incentive. I think lots of people would love to do it because schizophrenia is
    0:31:39 1% of the population. This is across populations, across cultures. So it’s a huge opportunity
    0:31:43 to make therapies that help patients. For what is not a rare disease.
    0:31:49 For what is not a rare disease. And if you go beyond that, again, as Bob’s book so amply
    0:31:56 demonstrates to the toll on people’s lives, it’s far beyond that 1%. We just don’t know how to do it.
    0:32:02 Not for the broad schizophrenia there. And this is where I came from my angle
    0:32:07 to sort of look at perhaps there might be subtypes of schizophrenia defined by genetics,
    0:32:11 where you really would have one particular form of schizophrenia.
    0:32:18 So Stefan, if you, as a researcher, if you could wave a magic wand right now,
    0:32:24 you know, you mentioned better models. What are the things that if you could wish something here
    0:32:29 tomorrow in the form of a new technology or a new capability, what would that be that would
    0:32:34 really push us forward into a new chapter? I’ll go way afield. But if we could monitor
    0:32:40 the brains of a schizophrenic with sufficient resolution with high resolution, right now we
    0:32:46 get about a millimeter voxel with the best bold fMRI experiments. While they’re actually having
    0:32:51 a psychotic break, the resolution is still, of course, could be made finer and finer. We still
    0:32:56 can’t get down to the level of a single cell. But now with the blood oxygen level dependent,
    0:33:02 magnetic resonance imaging, we can get a measure of function in somebody’s brain in real time.
    0:33:05 Difficult to do, takes a lot of equipment, takes a particular stimulus,
    0:33:08 but one could perhaps hope that this will lead to more insight.
    0:33:13 Oh my gosh, how fascinating that we’ve never seen. We actually have no idea what’s really happening.
    0:33:18 I mean, consider the logistics. You can’t consent somebody and get them to sit in a machine and
    0:33:24 then wait for them to have a psychotic break. Yeah. What would you be looking for?
    0:33:31 We need mechanism. If the field as a whole could say, here is a particular area where the excitability
    0:33:37 is abnormal, an area of brain tissue that is abnormally excitable, or a particular receptor
    0:33:43 that is abnormally excitable, that gives us a good place to start. That gives us mechanism.
    0:33:48 And then perhaps we could study what do existing drugs do to that. What is missing with existing
    0:33:55 drugs? That’s fascinating. It almost sounds like you need like a wearable MRI, a very high resolution.
    0:34:04 Silicon Valley, go to it. What about things like CRISPR? If you do start defining some very specific
    0:34:09 narrow, very entirely genetic cause, is that a possibility as well?
    0:34:17 So we’ll give a possibility. Say if we knew that a baby galvan or their modern-day counterpart babies
    0:34:23 had a variant in a gene that we thought because of families like the galvanes that we had good
    0:34:28 reason to believe would make them develop schizophrenia. Can we get in there and change
    0:34:36 that one nucleotide to the wild type? It’s conceivable, but again the challenge here is
    0:34:43 the engineering challenge. We can do it in a dish, but trying to get just that one gene edited,
    0:34:50 trying to get it in just that one nucleotide changed in every cell in the brain and no changes in
    0:34:56 any other nucleotides in the brain and delivering something that will actually cross the blood
    0:35:02 brain barrier and then doing it on an infant. How would you even test this? Very, very difficult.
    0:35:08 Bob, you describe when Lynn Delisi first met the galvan family and you write this incredibly
    0:35:12 profound line that really stuck out for me. As she walked through the door of the house at
    0:35:17 Hidden Valley Road, she couldn’t help but recognize a perfect sample. This could be the most mentally
    0:35:23 ill family in America and you really dove into every element of what that meant for them into
    0:35:31 this family’s innermost suffering and struggles. It was just so intimate on some level and also
    0:35:36 such a big story on another level of not just schizophrenia, but the way we struggle with
    0:35:43 all mental illness, including trauma and depression. What was the kind of big takeaway for you for
    0:35:50 having lived inside this family’s mental illness for several generations, really?
    0:35:56 Well, I really think the day, hopefully not too long from now, that all this research yields real
    0:36:02 rewards will be the day that this family’s sacrifice will finally find its true meaning.
    0:36:08 But also, this is a story about experiencing unbelievable and mysterious tragedies one after
    0:36:13 the other and coming out the other side. There are members of this family who have found a way
    0:36:16 through this and found meaning in life when everything seemed to be going against them.
    0:36:22 It’s really about the value of family, in my opinion, this story and the hope for the future.
    0:36:26 Stefan, on the research side, what’s coming that we should be aware of that might be
    0:36:29 bringing hope to the next generation of Galvans?
    0:36:34 It’s tough. I could answer this for Parkinson’s. I could answer for Alzheimer’s. I could answer for
    0:36:39 any number of diseases. Schizophrenia is really, really tough. We need some help. We need something
    0:36:44 to break in the academic world and that break will come from studying people. There are ever better
    0:36:50 ways of studying what is really going on with human biology in people who are kind enough and
    0:36:55 selfless enough to volunteer themselves and their families for research. Not just their genome,
    0:36:59 we can measure the protein circulating in their blood. There are ways to do this massively in
    0:37:04 parallel. Stem cells, organoids, I think it’s too early to see if these are going to be helpful,
    0:37:09 but no question, these are a way to explore. People can do longitudinal studies for how people
    0:37:14 are changing over time. Imaging lets us look into the brain better than ever before and these
    0:37:20 technologies just keep accelerating and improving. We need somebody to set the goalposts. There’s
    0:37:26 a lot of advanced technology. Technology will drive biology. We are focused on human subjects.
    0:37:32 Something’s got to break. That’s amazing. Thank you so much for both of you joining us on the
    0:37:44 A16Z podcast and here’s hoping we get to that break soon.

    Descriptions of the mental illness we today call schizophrenia are as old as humankind itself. And more than likely, we are are all familiar with this disease in some way, as it touches 1% of us—millions of lives—and of course, their families. In this episode, we dive into the remarkable story of one such American family, the Galvins: Mimi, Don, and their 12 children, 6 of whom were afflicted with schizophrenia.

    In his new book, Hidden Valley Road: Inside the Mind of an American Family, Robert Kolker follows the family from the 1950s to today, through, he writes, “the eras of institutionalization and shock therapy, the debates between psycho-therapy versus medication, the needle-in-a-haystack search for genetic markers for the disease, and the profound disagreements about the cause and origin of the illness itself.” Because of that, this is really more than just a portrait of one family; it’s a portrait of how we have struggled over the last decades to understand this mysterious and devastating mental illness: the biology of it, the drivers, the behaviors and pathology, the genomics, and of course the search for treatments that might help, from lobotomies to ECT to thorazine.

    Also joining Robert Kolker and a16z’s Hanne Tidnam in this conversation is Stefan McDonough, Executive Director of Genetics at Pfizer World R&D, one of the genetic researchers who worked closely with the Galvins. The conversation follows the key moments where our understanding of this disease began to shift, especially with new technologies and the advent of the Human Genome Project—and finally where we are today, and where our next big break might come from.

  • Elizabeth Warren has a plan for this, too

    In January, Sen. Elizabeth Warren was the first presidential candidate to release a plan for combatting coronavirus. In March, she released a second plan. Days later, with the scale of economic damage increasing, she released a third. Warren’s proposals track the spread of the virus: from a problem happening elsewhere and demanding a surge in global health resources to a pandemic happening here, demanding not just a public health response, but an all-out effort to save the US economy.

    Warren’s penchant for planning stands in particular stark contrast to this administration, which still has not released a clear coronavirus plan. There is no document you can download, no web site you can visit, that details our national strategy to slow the disease and rebuild the economy. 

    So I asked Warren to return to the show to explain what the plan should be, given the cold reality we face. We discussed what, specifically, the federal government should do; the roots of the testing debacle; her idea for mobilizing the economy around building affordable housing; why she thinks that this is exactly the right time to cancel student loan debt; why America spends so much money preparing for war and so little defending itself against pandemics and climate change; whether she thinks the Democratic primary focused on the wrong issues; and how this crisis is making a grim mockery of Ronald Reagan’s old saw about “the scariest words in the English language.”

    0:00:27 Doss, and this episode is all about what the numbers, both financials and KPIs, do and
    0:00:32 don’t tell you about your business. Our guests for this episode are A16Z General Partner and
    0:00:37 Managing Partner Jeff Jordan, who previously ran several businesses and took a company
    0:00:42 public right after the 2008 financial crisis. David George, who runs our late-stage venture
    0:00:47 operation, and Caroline Moon, who leads our financial operations practice and helps companies
    0:00:54 with their own best practices. She’s also a former CFO. In our conversation, we cover
    0:00:58 the most common mistakes people make when it comes to understanding numbers. When investors
    0:01:03 think when they look at a company’s profit and loss statement and why, how investors
    0:01:07 use metrics to determine if a business is healthy, and how some founders may use them
    0:01:13 to navigate times of crisis. We begin, though, with the basics of the three core financial
    0:01:18 statements, the income or PNL statement, the balance sheet, and the cash flow statement.
    0:01:24 The first voice you’ll hear after Caroline’s and mine is Jeff’s, followed by David’s.
    0:01:28 Especially in the early days of a startup, they’re just going to do cash accounting,
    0:01:30 and that’s just literally how much cash you had in the beginning of the period and how
    0:01:35 much you had cash at the end of the month. That’s not the same thing as what a PNL really
    0:01:41 should show, because your PNL paints the picture of how your business did in a particular period
    0:01:46 of time and measurement, whether that’s quarterly or yearly, or the cash statement then reconciles
    0:01:49 that with what did you actually collect. Everything that happens on that cash flow
    0:01:52 statement then ends up on your balance sheet.
    0:01:57 The reason why it’s important to be able to present it in that fashion, it’s called generally
    0:02:03 accepted accounting principles, so GAP accounting, is because that’s how everyone understands
    0:02:08 that the comparisons are apples to apples when you look across companies.
    0:02:12 When you are trying to figure out how a business is doing, what are the financials that you
    0:02:13 look at?
    0:02:20 Typically, the early investing, you don’t emphasize financial metrics that much, because
    0:02:24 usually, there isn’t a mature go-to-market organization. I tend to focus much more on
    0:02:31 KPI-type metrics, users, daily to monthly users, engagement, and things on those lines,
    0:02:34 and then the financials tend to emerge over time.
    0:02:40 Yeah, I would say I care most about two very high-level topics at the later stage. The
    0:02:47 first is, can you demonstrate that you can have very persistent growth? Secondly, how
    0:02:53 profitable will you be when you reach scale? I spend less time for later-stage high-growth
    0:02:58 companies staring at their balance sheet than I do KPIs, income statements, and cash flow.
    0:03:02 The main thing I look for in the balance sheet is the comparison for how much traction they
    0:03:06 have on the income statement and the cash flow documents relative to the amount that’s
    0:03:10 been invested in the company. For me, the most important balance sheet metric early
    0:03:15 is how much capital is the company deployed to get to where they’re going.
    0:03:19 How do you guys know when a business is truly profitable?
    0:03:24 I do think you go to the unit economics and really understand them, but this is often
    0:03:29 a lot of art as well as a good amount of science. Some of the most frustrating interactions
    0:03:34 I’ve had with companies are where they’re presenting that their unit economics work,
    0:03:38 but the business isn’t working. And so I had one where, okay, we’re capital efficient,
    0:03:43 the unit economics are working, we acquire users, they’re profitable in three months,
    0:03:48 and the company was hemorrhaging cash. It turns out the unit economics actually weren’t working.
    0:03:53 The cash flow statement was the arbiter of truth and the analysis that the company had
    0:03:57 done on unit economics was wrong. Yeah, I agree. I think lifetime value is one
    0:04:01 of those traps that people fall into. They’re assuming, oh, our customers are going to stay
    0:04:05 with us for five years, three years, so we’ve got plenty of time to do the payback,
    0:04:09 but that’s a key driver to whether or not your unit economics work.
    0:04:14 There’s nothing that’s less consistent in the market than how lifetime value to
    0:04:20 cost of acquisition of the customer. LTV to CAC is defined. What I always counsel companies and I
    0:04:26 like to see is very transparent calculations of what goes into the LTV side and the CAC side.
    0:04:33 So the LTV to CAC metric that I like to look at is for the LTV, so the lifetime value side,
    0:04:38 I always use gross profit, not revenue. And then I like to use a shorter duration than
    0:04:43 founders typically like to use. So I like to use three years. Often founders present five years,
    0:04:47 and the point I make on that is that five years is too uncertain and long of a period of time,
    0:04:52 whereas three years is much more visible, and then use actual retention statistics that you’ve
    0:04:57 experienced in the past to project those three years. The thing that I really try to emphasize
    0:05:03 to founders when they talk about these kinds of metrics is, look, this is not about necessarily
    0:05:07 showing investors. This is how you have to run your business. What am I spending on sales and
    0:05:12 marketing? What am I spending on my R&D? And how much am I spending on G&A? And is that
    0:05:17 the right level of investment that I should be making in my company? So you need to be as honest
    0:05:21 with yourself as possible as to what all these things cost you and what you’re really generating
    0:05:25 in terms of revenue, because if you can’t be honest with yourself, you can’t run your business.
    0:05:30 What are some of the other really common mistakes or things that founders do in presenting numbers
    0:05:34 that you’d want to help them correct or you’d like to see them do differently?
    0:05:39 You know, one tell for me where business is probably struggling is when they come up with
    0:05:46 North Star metrics, you know, KPIs, and then when they come back to report on them a quarter later,
    0:05:50 they’ve changed. And then they come back a quarter later and they’ve changed again. And what I found
    0:05:55 a little bit of pattern recognition is when the KPIs change all the time, it’s largely because
    0:06:01 they’re not working. And the company’s trying to navigate through it. For me, you pick your metric,
    0:06:07 you report on it. And ideally, your understanding of the business improves over time as your metric
    0:06:12 and your models are either validated or unvalidated. That leads this interesting question, I think,
    0:06:18 of the psychology and how you look at your numbers. So how do you manage your own psychology
    0:06:21 so that the numbers are a tool, not this obsession where it’s like,
    0:06:26 my obsession is I want to reach my KPIs. So I’m going to keep adjusting my KPIs. So I do.
    0:06:30 You know, the reason they’ve so defined the three financial statements is it’s kind of truth-seeking
    0:06:36 and trying to fool your investors or lack of better word or your board. You know,
    0:06:42 I don’t want to let them know how bad things are. By not telling the truth to your key constituents,
    0:06:47 you often run the risk of not telling the truth to yourself. And so I’ve had a couple founders
    0:06:53 where sometimes they fall prey to it themselves, where they believe their own machination,
    0:06:57 and then the board and investors can’t help them based on the truth.
    0:07:03 What do the best founders do, especially in challenging moments, like when the finances
    0:07:07 and the numbers maybe aren’t going your way, or you know that you do have to tell a difficult truth?
    0:07:13 They typically acknowledge it. They take it as, okay, the truth isn’t what I wanted it to be.
    0:07:17 So now, what can I do to change the business to improve the truth?
    0:07:21 The only thing I would add to that that I’ve observed from some of the best founders of
    0:07:28 later stage companies is they’re very careful not to drown themselves in KPIs. So you can actually
    0:07:34 inundate yourself with KPIs, but the very best ones pick out a very few handful of metrics that
    0:07:39 they think are the most important drivers of their business. And if they see those divert from where
    0:07:44 they would like them to be, they dig in from there. So for example, Ali from Databricks always
    0:07:50 focuses on the productivity of a sales rep because he believes that indicates health
    0:07:55 of the business in many different ways. So how well is the sales organization actually functioning?
    0:07:58 What are the market dynamics? What’s competition? How is the product performing?
    0:08:03 And you do get a real force for the trees. I have companies that will present you 50 pages
    0:08:09 of metrics based on the last quarter and you just drown versus what in here is really important?
    0:08:13 What are the key ones? Are the one or two that matter the same for every company or does it
    0:08:18 depend on the nature of the company and the stage that they’re at? I think to some degree,
    0:08:22 some of them are the same. For instance, retention should matter to any business model.
    0:08:26 You spent money to acquire your customer base. How long are you hanging on to them?
    0:08:31 Yeah, I find they are consistent by type of business. So marketplace metrics typically
    0:08:36 have a lot in common with each other, but they’re very, very different than e-commerce metrics.
    0:08:40 The key e-commerce metrics typically center around the efficiency of customer acquisition
    0:08:46 and LTB to CAC. A lot of marketplaces I work with don’t spend a penny on customer acquisition.
    0:08:52 And so it’s got organic distribution or something like that. So comparing across models can be
    0:08:58 challenging. Comparing within models can be very helpful. So for B2B companies, for example,
    0:09:03 the efficiency with which you spend a sales dollar, whether it’s on a rep or marketing
    0:09:07 or bottoms-up sales, inside sales, outside sales, is always one of the most important things that
    0:09:12 you look to. Things change. Markets are unpredictable, which is something I think we’re seeing now
    0:09:18 more than ever. How do you use finances to make better, faster decisions, especially in uncertain
    0:09:24 times? You know, I started my career in finance. I ended up as CFO at the Disney Store. So it’s
    0:09:28 near and dear to my heart. The typical finance function is conceived of as kind of keeping score,
    0:09:34 the accounting control function, just reporting back. For me, that was necessary but not sufficient.
    0:09:39 The finance function has access to all of the key data. And so I look at them not only to keep
    0:09:45 score, but to score points to make the business better by leveraging their access to the information
    0:09:49 and to the trends and to the unit economics to improve the business.
    0:09:57 A good finance leader needs to work with the CEO to make sure that the company has
    0:10:04 enough money to not just survive but thrive. So that is becoming super intimately familiar
    0:10:08 with the business, not the financial statements, not the accounting that goes into developing
    0:10:11 these things, because those just represent what’s happening at the business level.
    0:10:17 They really need to understand how everything works and then where are the levers that you can
    0:10:22 change, that you can pull on, that you can push on to accomplish the things that you want to do
    0:10:27 as a business in the timeframe that you need it all backs up with the cash that you have on hand.
    0:10:32 When I was managing businesses, I always had a mental model of how the business should work.
    0:10:37 And that mental model typically, ideally, was consistent with the financial model.
    0:10:43 eBay, back when I managed it, was a perfect economy. And eBay as a platform attracted every
    0:10:48 leading finance professional who was into micro because it was one of the most pure examples
    0:10:54 of a perfect economy. If there was an increase in supply, prices fell. If you change the fee
    0:11:00 structure, behavior changed. And so it’s when businesses diverge from my mental model that
    0:11:05 you really needed to pay attention. It’s like, why is the conversion rate going down? My god,
    0:11:10 I’ve never seen it go down like that. That’s a big warning indicator for me. So I would
    0:11:15 typically be pretty comfortable running the business until anomalies emerge. And then I just
    0:11:19 would need to understand the driver of the anomaly. And I can’t emphasize enough how important it is
    0:11:24 for companies to understand their bottoms up for how revenue is generated. I see a lot of people do
    0:11:30 tops down forecasting. So the last quarter, we had whatever, a million dollars in revenue, 10
    0:11:35 million dollars revenue. And then you go, okay, and historically, we’ve grown 50% or 100%. And so
    0:11:41 we’re going to model something similar to that for the next year. And so that’s our number.
    0:11:45 And that’s got no intelligence built into it whatsoever. What you have to do is double click
    0:11:50 on that and go, okay, so we made whatever $10 million last year, how was it made? What was the
    0:11:55 makeup of that customer base? Who’s likely to still be here? Who’s going to spend more? Who’s
    0:12:00 not going to spend more? Who’s going to completely leave the platform? In marketplaces, you often
    0:12:05 get two shots at bottoms up because you typically can build a model based on the supply,
    0:12:09 or you can build a model based on the demand. Get an example at eBay. We would look at the
    0:12:15 behavior of sellers and we had this many sellers growing this fast, doing this kind of behavior,
    0:12:20 and then you just kind of roll them together and come up with a revenue estimate. Then we’d sanity
    0:12:26 check it with, we have this many buyers buying this frequently, spending this much and coming onto the
    0:12:31 platform at this rate. And then you’d run up that number. And ideally, the two would inform each
    0:12:37 other. So one of the best CEOs who I worked with, who I partnered with was George Kurtz from Crowdstrike.
    0:12:42 He had an exceptional business. One of the things when we were working together that we came to
    0:12:48 realize was his gross margins were a little lower than most other software companies that we were
    0:12:54 working with. He actually made the decision in one quarter based on that to try and experiment
    0:13:00 where he made gross margin actually be part of the calculus for sales compensation for the reps
    0:13:06 in that quarter. And his gross margins over the last three years have actually gone from 35% to 70%.
    0:13:12 So a very operational tactical decision that can have a massive impact on the value of the business.
    0:13:17 So I wanted to go back to a point, I think, Jeff, that you brought up of having this mental model
    0:13:22 of your business and hoping that that matches the financials and how then you have those red flag
    0:13:27 moments. And I think a lot of companies right now are having a red flag moment because of a
    0:13:32 lot of circumstances very beyond their control. I’d love to hear, what are you telling founders
    0:13:37 right now when it comes to how to think about their financials? This is one of the most significant
    0:13:41 disruptions I’ve experienced. I’ve had a long enough career that I’ve experienced a bunch of them,
    0:13:47 the bubble bursting in 99, 2000, the financial crisis of 2008, 2009, which by the way, we took
    0:13:54 OpenTable public in May 2009. So the future isn’t dictated. But a couple of things come to mind.
    0:13:59 One is cash is king. The income statement, throw it away. Just look at the cash flow statement.
    0:14:03 How much cash do you have? How’s the burn? How are you adding or using cash over time? So
    0:14:08 cash becomes completely king. Throw out your forecast because the forecast is now meaningless.
    0:14:13 It was based on a bunch of assumptions that no longer hold. So throw the financial print out
    0:14:17 and start looking really hard at things like year over year, which typically doesn’t lie.
    0:14:23 And then just do tons of sensitivities. And you got to do it decisively. I always like this thought
    0:14:31 exercise of how bad could this possibly get? Just let’s take the absolute worst. How bad could it
    0:14:37 get? Because I think people tend to do the opposite. They iterate down of like, okay, I’m going to,
    0:14:42 we’re down 5%. I’m going to plan down 10%. But if it’s going down 5% per day,
    0:14:47 plenty down 10% just met your plans out late in two days. And so I found it helpful both from a
    0:14:52 business, prudent cash management perspective, also from a mental perspective. Don’t let this
    0:14:57 just continue to erode. And I get more and more depressed every day. Get really depressed one
    0:15:02 day, look at reality and then try to change it. Yeah, I agree. So I was a CFO at a company
    0:15:07 called Adbride in 2008. And I think that at first we didn’t want to believe that it could get that
    0:15:12 bad. But we were an advertising network. And so unless you were Google and even they were impacted
    0:15:16 by this, your customers weren’t going to advertise anymore. The marketing departments were decimated.
    0:15:21 So there were situations where we were like, some of this is just going to become zero.
    0:15:26 Contracts that were signed are now just getting outright canceled. So we made the decision to
    0:15:31 cut really deep and as quickly as possible. Because we knew that even if we got it wrong,
    0:15:37 at least we could then rebuild the company and do it only once. And then your employees then
    0:15:41 are told, hey, we’ve made this big decision. Here’s what we based it on. Here’s our cash
    0:15:45 position. Here’s what we’ve sort of expecting in terms of worst case scenario. You bring them
    0:15:50 into that circle of trust of what’s happening at the company. But there’s asymmetric potential
    0:15:57 issues. If you underestimate how bad it’s going to get and don’t deal with the situation quickly,
    0:16:01 the outcome is very well be you lose your company. Yeah, death by a thousand cuts.
    0:16:05 Yeah. And if you overreact and it doesn’t end up being as bad as it would have been,
    0:16:11 you might have suboptimized your company for some period of time, but it’s alive.
    0:16:16 So for me, the mistake is to underestimate the potential versus overestimating.
    0:16:20 Yeah, I want to go back to something Jeff said, which was this notion of throwing your forecast
    0:16:26 out the window. Very much agree with that on the top line on your revenue. But you have this whole
    0:16:30 base of costs that are under your control, those are your operating expenses. And so
    0:16:36 we’ve spent a lot of time focused with our companies running sensitivities of, hey, this is
    0:16:41 your operating expense budget. And what’s an operating expenses are your salespeople, your
    0:16:47 marketing people, your CFO function, your HR function, your engineer’s product. Those are all
    0:16:54 people and costs that you have as a base. What happens to that cost base in order to preserve
    0:17:00 cash under various scenarios of revenue decline? And so I think that’s the way that you have to
    0:17:05 be managing your business on a very, very granular level. And especially since companies,
    0:17:10 especially startups, they staff in advance of growth. And so you have to really be honest with
    0:17:16 yourself. I want to just also chime in and just say, look, these are all very, very hard decisions.
    0:17:22 And I think Caroline and Jeff, especially because you’ve been in the seat of operators
    0:17:27 during really, really trying times, you’re probably pretty diagnostic about it. But suffice
    0:17:32 to say it’s hard decisions, you know, people’s jobs, decisions not to be taken lightly.
    0:17:37 And that’s why there are cases where it is a death by a thousand cuts because people are reluctant
    0:17:43 to do those layoffs, make those cuts. And believe me, you don’t sleep when you have to make these
    0:17:48 decisions. It’s so tough. So I don’t take that lightly at all. But when you’re running a company,
    0:17:53 number one is making sure the company can make it through to the other side. And so you have to
    0:17:58 make these really tough decisions. And believe me, I understand how difficult that can be.
    0:18:00 But you can’t kick the can down the road on some of these things.
    0:18:06 Everyone in the organization knows that the proverbial shit is at the fan. And so if the
    0:18:13 leader is unwilling to acknowledge that with the team, that for me creates a crisis of confidence.
    0:18:20 I always found it way better just to call it what it is, share it, try to enlist the team. And
    0:18:24 do you agree with this version of reality and try to get agreement? And then it’s like, okay,
    0:18:29 what do we do? But denial and trying to hide it from your team is a failing strategy completely.
    0:18:34 And I understand the human psychology around that because I think people don’t like to give
    0:18:39 bad news. And so I think the natural impulse is to hide those things. But these are the moments
    0:18:44 where you have to actually be the most transparent. Talk about why you’re doing what you’re doing,
    0:18:48 how much cash you’ve got left, how much you want to preserve. And what I find is when you do that,
    0:18:52 when you bring everybody into the fold, they all become part of the solution. So they understand
    0:18:58 that cash is king, and they’ll figure out ways to be even scrappier than they might have been
    0:19:03 otherwise. Jeff, you’ve lived through some crises already. Go back to a time when you were facing
    0:19:07 a crisis where things were rapidly changing. You were having to make some of these difficult
    0:19:13 decisions. What was a day in a life like then? And what were you doing, especially with regards to
    0:19:20 the financials? I got a good one for you. So OpenTable in mid-2008, the board decided it’s
    0:19:25 time. Let’s go public. The market wasn’t good. But for a variety of internal reasons for the
    0:19:29 company, we decided, okay, we have to, quote unquote, get the puck on the ice. And so we got
    0:19:36 ready for the IPO. And we did our bake-off in, I think it was August 2008 and did it like on a
    0:19:42 Thursday. And Friday, we informed the six banks whether they got on the offer or not.
    0:19:46 We told Lehman on Friday they didn’t get the offer. They went out of business on Saturday.
    0:19:51 We told Merrill Lynch, they did get the assignment to take OpenTable public,
    0:19:57 and they traded to Bank of America on Sunday. So over that weekend, the number of people dining
    0:20:03 in fine dining restaurants in America went down by 15% in one weekend. So we had the org meeting
    0:20:07 Monday morning. I walk in, sit down, all the bankers there, all the lawyers there, and this is not
    0:20:15 going well. Our business is in free fall. The bank just changed. The consumers terrified. And so
    0:20:20 it was pretty clear we could not proceed with the IPO at that point because we couldn’t predict it.
    0:20:25 But then we just said, okay, what can we predict? And so we put it on hold for three or four months.
    0:20:30 And it turned out that the consumer kept dining in restaurants at 85% of what they had the prior
    0:20:34 year. And all of a sudden, we got confident that the business was predictable at that point. And we
    0:20:38 restarted the process and went out. And it ended up being a successful offering.
    0:20:42 How were you looking at the financials during that time? How did those come into play as you went
    0:20:47 through that? We were watching the year-over-year change in reservations of people dining and
    0:20:52 reservations made daily, just like, okay, where’s this business going? Because if it kept falling,
    0:20:57 one of the scenarios we were concerned by is more and more people would stop eating as they got more
    0:21:03 and more nervous about the economy. And we’d go from revenue of X to revenue of like 0.3X. And the
    0:21:08 business would have been hugely stressed at revenue of 0.3X. So we were watching that the
    0:21:15 one key North Star metric of diners per night, year-over-year, maniacally. And that ended up
    0:21:19 giving us the confidence to restart the offering. How does a startup or a founder right now approach
    0:21:24 contingency planning around their finances, especially if you’re a high growth startup that’s
    0:21:29 been going through cash quickly and been pretty aggressive with your risk taking until now?
    0:21:36 For me, you don’t scenario plan constantly. But when a shock hits the system like this shock has
    0:21:44 hit this system, hit the world, is you want to plan quickly, even if it’s bluntly. If I was running a
    0:21:50 business in this environment, I would get the expected outcome. Maybe it won’t go there quickly,
    0:21:55 outcomes are slightly better, but also just what is the worst case? Where could this go? And then
    0:22:02 you build your response if each of those comes true. And for me, you put much more time into the
    0:22:08 plan, what if, than you do in the building the sensitivity scenarios. One of the less productive
    0:22:14 activities is making that sensitivity beautiful and accurate. And it takes two months to come out
    0:22:19 with and the company’s out of business. Yeah, just take the bluntest assessment. David and his team
    0:22:24 has done this for a few of our internal companies. Yeah, what we did is we basically took every
    0:22:30 company’s financials and started with revenue and said, okay, let’s start with your budget.
    0:22:36 And then let’s run sensitivity analyses for your revenue. Let’s assume you hit your budget,
    0:22:42 that you’re flat, that you don’t grow, that you declined by 25% or that you declined by 50%.
    0:22:48 And then we compared that with a company’s operating expense budget. And across all those
    0:22:54 different scenarios, if you run your current budget of operating expenses, if you assume you
    0:22:59 don’t grow your operating expenses, and then if you assume you decline your operating expenses by
    0:23:05 25% or 50%, what is your cash runway in each of those scenarios? And we plug that in for each of
    0:23:11 our companies and gave it to them. And I think it’s just a helpful way for them to put some parameters
    0:23:17 around, hey, if things get really bad, this is what our runway is. And often it helps them just to
    0:23:23 start thinking about, okay, how do I contingency plan in the event of flat revenue? I had never
    0:23:27 even thought about that before. If that happens, I only have this much runway. Maybe I should take
    0:23:32 action. And another thing that I would say to you, a lot of times companies are building things as the
    0:23:37 plane is in the air, and they solve their problems linearly by throwing bodies at it. This is an
    0:23:42 opportunity to be able to potentially refactor your code base, to shore up infrastructure,
    0:23:48 to build internal tools to make your teams more efficient, so that when you do come out on the
    0:23:53 other side, that you are primed and ready to just hit the ground running and run in a million miles
    0:23:57 an hour, because you have now built the foundation that you need to be able to really scale your
    0:24:02 business, a company called AdBright. We were an ad network. This was before Amazon Web Services was
    0:24:07 really a big thing. And so you had to have your own data centers, which means you had to buy
    0:24:13 equipment. So we were a very capital intensive business. And what we realized was that we weren’t
    0:24:17 going to be able to afford anymore to be constantly replacing our servers, because we just did not
    0:24:24 have the money to do it. And our CTO had been playing around with this thing called AWS and
    0:24:29 brought it to us and said, one, we can’t afford to upgrade our servers, even though we need to.
    0:24:34 And two, this is going to probably in some ways improve our gross margins, because now
    0:24:39 we can flex up and down when we need the capacity. So can we give it a try?
    0:24:46 This was cloud-based. Anything was still pretty new. This was 2008, I think, AWS launch in 2006.
    0:24:50 So we became a data customer of theirs. At the end of the day, when we came out of the crisis,
    0:24:56 we were pretty much a cloud-based ad serving company. We deprecated all of our data centers
    0:25:01 when we just moved everything to AWS. So what bottom line advice right now are you giving to
    0:25:07 founders? One anecdote about the 2008 credit crisis, when housing prices dropped like 30
    0:25:11 to 40%, if you were to interview people on the street who owned homes, you asked them, hey,
    0:25:15 what do you think the US residential market has done in terms of real estate values?
    0:25:20 They would across the board say, oh, it’s down 30 to 40%. And then they would be asked,
    0:25:25 all right, what do you think happened to the value of your own home? And they say, oh, nothing,
    0:25:28 nothing at all. It’s still fine. It’s not down at all. And it’s like, well, that’s not how averages
    0:25:33 actually work. And so no one believes that it’s going to happen to them. But believe me, it is
    0:25:39 happening to them. And that is the thing that I want founders to understand. You are not going to
    0:25:43 be impacted asymmetrically compared to everybody else. You’re not going to be that outlier more
    0:25:49 likely than not. So we’ve had a lot of advice in here on confront reality decisively, plan for
    0:25:56 the worst case, scenario plan the worst case. And psychologically, that is pretty darn challenging
    0:26:01 on the founder. I mean, I’ve lived it, I understand there. So that brings the point that it’s just
    0:26:06 incredibly important for the founder to manage their own psychology. And I think probably the
    0:26:10 best resource I’ve read on that is Ben’s book, The Hard Things About Hard Things. You flip from
    0:26:17 peacetime to wartime, people are looking for you to lead, and you’ve just got to take the horn.
    0:26:23 But I always was most uncomfortable with my personal psyche when things were going great.
    0:26:30 I mean, when OpenTable was trading for like 21 times forward revenues, which is an absurd valuation,
    0:26:36 I was jumping out of my skin. But once you confront the fact that, okay, we’re in one of those
    0:26:42 moments and I need to lead out of it, I actually found it after an absolutely miserable X hours.
    0:26:48 I found it motivating. We can get over this, let’s show them what we can do. For me, the CEO and
    0:26:54 founder needs to confront reality quickly and then they need to lead. And you can lead your company
    0:26:58 through these things and get to the other side, then things will get better again. But the biggest
    0:27:03 thing is manage your psychology actively. I just want to thank you, David. Thank you, Jeff. Thank
    0:27:07 you, Caroline, for joining us on the podcast today. Thank you. Thank you.

    For any business, there are three core financial statements – the income or P&L statement, the balance sheet, and the cash flow statement. While these statements can show investors and the board how the business is doing, they can do more than just keep score on your business – they are one of the best tools you have to run it.

    In this podcast, a16z General Partner and managing partner Jeff Jordan, who previously ran several businesses and took a company public right after the 2008 financial crisis; David George, who runs the a16z late-stage venture operation; and former CFO Caroline Moon, who leads the a16z financial operations team, break down what the numbers do (and don’t) tell you, both in financial statements and KPIs. They cover the most common mistakes people make when it comes to understanding their numbers; how investors look at a company’s P&L; what metrics they use to determine if a business is healthy; and how founders can use the numbers to navigate in times of crisis.

    0:00:20 Hi, and welcome to the A16Z podcast.
    0:00:22 I’m Lauren Murrow.
    0:00:26 Since social distancing measures were first put in place, time spent gaming has gone up
    0:00:28 75% during peak hours.
    0:00:34 In this hallway-style conversation, A16Z partner John Lai joins me to talk about how the stay-at-home
    0:00:39 movement is fueling gaming, what we’re playing, and why live streaming is having its moment.
    0:00:44 Playtime in general is up massively across every category of gaming.
    0:00:49 PC games erupt, steam, the world’s largest marketplace for digital PC games.
    0:00:54 Steam has been around for 20 years and it’s never seen this level of user activity.
    0:00:59 Average concurrent users online typically hover around 15 million.
    0:01:04 It hit an all-time record high this past Saturday, around 22 million concurrent users online.
    0:01:07 So that’s a spike of almost 50%.
    0:01:09 Console games are up massively as well.
    0:01:10 What is driving this spike?
    0:01:15 Obviously, we’re all at home more, but what other factors are coming into play?
    0:01:20 So I think what’s special about games versus other types of media is that gaming is a
    0:01:24 massive activity that a set of friends can engage in at the same time.
    0:01:30 There are moments of levity, competition, there are emotional highs and lows over the
    0:01:32 course of a typical gaming session.
    0:01:36 These are bonding moments for people and they create really deep social relationships.
    0:01:40 It seems like smart game studios are also putting measures into place to encourage more
    0:01:41 at-home play.
    0:01:46 I know Pokemon Go changed its mechanics a bit to make it easier for people to play
    0:01:47 from home.
    0:01:50 It changed its events to make it easier for people to play alone.
    0:01:51 Absolutely.
    0:01:54 Blizzard of World of Warcraft, which is one of the largest and longest-running MMOs of
    0:01:59 all time, launched a whole series of benefits during quarantine so that if you’re playing
    0:02:05 right now, you actually get double experience as a way of incentivizing people to continue
    0:02:06 playing the game.
    0:02:09 What kinds of games are popular amid this crisis?
    0:02:10 Are there particular titles?
    0:02:15 One game that I’ll highlight as an example is a fairly recent one, Call of Duty Warzone,
    0:02:19 which is a new battle royale game from Activision that just launched March 10th.
    0:02:24 It ended up being one of the most successful and fastest growing PC console game launches
    0:02:25 in history.
    0:02:30 Over the course of three days, it reached 15 million players, and I think it reached
    0:02:32 30 million players after two weeks.
    0:02:37 I saw Infinity Ward had 6 million players in its first 24 hours.
    0:02:41 I think a lot of games that are launching this month are seeing major spikes.
    0:02:48 So Xbox Live, which is the multiplayer service for Xbox consoles, has had several outages
    0:02:52 twice over the last week as more users logged on than the infrastructure can handle.
    0:02:56 And Microsoft has some of the world’s best cloud infrastructure, so if they’re having
    0:02:58 trouble with it, it’s got to be a lot of people logging on.
    0:03:03 I’ve read of developers experimenting with ways to include a higher player count and
    0:03:08 larger squads with all these new users, but that’s also potentially risky.
    0:03:12 As you mentioned, Nintendo, Xbox Live, and Discord have all experienced outages within
    0:03:13 the last month.
    0:03:17 How are game developers responding to this massive influx of players?
    0:03:19 Yeah, it’s a double-wed sword.
    0:03:24 On one hand, you have unprecedented numbers of users coming to your servers, and you want
    0:03:26 to be able to support them.
    0:03:31 Increasing the number of users currently in a session is one way to try to minimize the
    0:03:37 sheer number of servers or shards that you need to spin up for a game, but at the same
    0:03:39 time that comes with its own technical challenges.
    0:03:42 And so I think everyone’s just struggling to keep the lights on.
    0:03:47 Discord announced that they had increased server capacity by 20% to keep up with demand,
    0:03:52 and promptly, right after making that announcement, they had server outages themselves as well.
    0:03:55 This isn’t something that’s just specific to games.
    0:04:00 Netflix, for example, just cap bit rates over in Europe, so in an effort to sort of keep
    0:04:06 bandwidth down, they’re no longer streaming in 4K or HDTV, and it’s clearly an attempt
    0:04:10 to contain costs and continue maintaining the quality of the service in the face of
    0:04:11 a lot of demand.
    0:04:15 Is there anything surprising that you’ve noticed in the types of games you’re seeing played
    0:04:18 more amid the coronavirus quarantine?
    0:04:25 Online multiplayer games are the ones that are seen the most obvious and largest growth,
    0:04:29 which makes sense because they’re fundamentally social games that you play with other people.
    0:04:35 I actually think that VR, virtual reality, might be seen as surge in popularity.
    0:04:36 How so?
    0:04:41 Well, the whole notion of VR is predicated on enabling people to escape the real world
    0:04:44 to a virtual reality, right?
    0:04:48 And even prior to COVID, there were early indicators that in-home consumer VR may be
    0:04:53 turning the corner, so the Oculus Quest was estimated to have sold well over a million
    0:04:56 units before it went in backorder.
    0:05:01 The Valve Index, which is perhaps the most powerful headset to date, sold out in minutes
    0:05:03 upon initial release.
    0:05:07 So VR headsets seem to have finally reached a price point and a hardware quality that
    0:05:08 has mass market appeal.
    0:05:13 And at the same time, you have exclusive AAA games coming to VR for the first time, titles
    0:05:21 like Half-Life Alyx, and Half-Life is arguably Valve’s biggest and most exciting IP, a sci-fi
    0:05:24 franchise that put them on a map, initially.
    0:05:29 It’s famous for ending the franchise essentially on a cliffhanger, and the resolution for the
    0:05:35 story is this Half-Life Alyx game, and it’s a VR exclusive, so you can only find out what
    0:05:39 happens if you buy a VR headset and you play in VR.
    0:05:44 Educational games are actually seeing tremendous growth as well these days.
    0:05:47 Teachers in schools are also holding online classes through Discord.
    0:05:49 I think that’s an interesting use case.
    0:05:55 So rather than platforms like Zoom, some are turning to apps that were traditionally gaming
    0:05:57 platforms like Discord or Twitch.
    0:06:02 Yeah, I think they’re picking the platform that their audience is already on.
    0:06:07 So if you’re an instructor and you’re trying to get kids to come online in order to listen
    0:06:13 to AP buyer or whatever subject matter you’re teaching, it’s going to be easier to convince
    0:06:17 them to come online if you pick Discord, because chances are they already use Discord to play
    0:06:18 their favorite games.
    0:06:23 So Discord actually just made a number of moves specifically to help educators come on
    0:06:24 the platform.
    0:06:29 It’s the user limit on screen change from 10 to 50 users, so you can accommodate larger
    0:06:30 class sizes.
    0:06:35 And in this case, the actual friction is on teaching the instructors, the teachers themselves
    0:06:36 how to use Discord.
    0:06:42 One thing in these gaming platforms is that as we’ve seen with video conferencing, the
    0:06:45 natural rhythm of the conversation is off.
    0:06:49 It’s difficult to respond without interrupting, sometimes it’s difficult to interject.
    0:06:57 So when it comes to learning how to have a live interactive conversation online, ironically
    0:07:03 I think gamers have received way more training in that area than almost any other demographic.
    0:07:09 Because the very nature of playing a game and chatting with someone over Discord or
    0:07:14 interacting with a livestream, it’s basically a constant act of juggling foreground versus
    0:07:15 background activity.
    0:07:19 And so being able to contact switch from okay, I’m listening to the lecture, to now I have
    0:07:22 a question and we’re going to talk about this question.
    0:07:26 This is something that gamers and then livestreamers in particular have a lot of experience with.
    0:07:31 And I think it’s interesting to think about how this might become an increasingly more
    0:07:38 critical skill in society as more teams and general folks start working and learning remotely
    0:07:40 versus in person traditionally.
    0:07:46 So you’re saying gamers may actually be prepared for this future whereas perhaps most of us
    0:07:49 who are not gamers may have a steeper learning curve?
    0:07:50 That’s right.
    0:07:53 John, I want to talk about who is playing.
    0:07:57 I think a lot of people have the conception that because schools are canceled in many
    0:08:03 places, a lot of it is teens and kids playing more video games.
    0:08:09 The average age of a gamer on League of Legends, for example, actually skews fairly old.
    0:08:14 I think it’s something in the 20s or the 30s, over time it’s crept up.
    0:08:19 And so you have a mix of adults, you have a lot of kids that are definitely playing since
    0:08:20 they’re out of school.
    0:08:24 And I think one of the neat things is that you have families that are coming together
    0:08:28 and playing games potentially for the first time as a sort of quarantine.
    0:08:35 Dungeons and Dragons, which is a tabletop fantasy RPG, has actually seen massive growth
    0:08:37 as well over the course of quarantine.
    0:08:42 In these turbulent times you end up having a lot of folks that are playing D&D together
    0:08:44 over Zoom and House Party.
    0:08:49 Those broadcast in the live streaming site Twitch is up 34% just in the last week, if
    0:08:50 you’re not familiar.
    0:08:55 It’s a tabletop game where a group of people role play a story and that story is often
    0:08:58 created just by another player of the game.
    0:08:59 It’s a giant improv party, essentially.
    0:09:04 Yeah, I think it’s important to remember that there’s this whole new audience that is rediscovering
    0:09:06 gaming as adults.
    0:09:07 Absolutely.
    0:09:11 A lot of people are coming back to games as a result of being housebound and they’re
    0:09:16 discovering that even though they may not have a console or a gaming PC, they actually
    0:09:18 already have an awesome gaming device on them.
    0:09:23 PUBG Mobile, which is the mobile version of a player unknown battlegrounds reported increased
    0:09:28 revenue of over 50% just in the last week compared to the prior week.
    0:09:33 One of the largest mobile games in the world, Tencent’s Honor of Kings grew from an average
    0:09:39 baseline of 60 million daily active users to over 100 million plus in February at the
    0:09:44 height of quarantine in China, and that’s 60% plus growth, which is pretty amazing given
    0:09:46 how large that game was to begin with.
    0:09:50 Essentially, you have a lot of new gamers rediscovering that they have a gaming device
    0:09:52 and perform at their smartphone.
    0:09:55 And some of these newcomers may be traditional sports fans.
    0:09:59 As in real life games and sporting events have been canceled, some of these leagues and
    0:10:02 teams have been moving online to a digital format.
    0:10:07 So about a week ago, the NBA turned one of their canceled games, I think it was Phoenix
    0:10:09 versus the Dallas Mavericks.
    0:10:14 They took that game and they actually turned it into an NBA 2K game, which is the video
    0:10:20 game equivalent of the real NBA, and it was livestreamed on Twitch for everyone to watch.
    0:10:26 It’s very trippy for me when I see an NBA star play their virtual persona in a video
    0:10:27 game.
    0:10:32 Well, and as NBA players have been put in isolation, I think many of them have been
    0:10:33 turning to gaming.
    0:10:37 There was a Call of Duty tournament for Miami Heat players that was also broadcast on Twitch.
    0:10:44 And NASCAR just replaced the canceled races with the first ever eNASCAR series where you
    0:10:47 were essentially piloting virtual race cars.
    0:10:51 And they brought back a lot of recent legends like Dale Earnhardt Jr. to drive those race
    0:10:52 cars.
    0:10:57 So professional race car drivers are competing against each other in racing simulation software.
    0:10:58 That’s right.
    0:11:03 So could eSports be a gateway to turn non-gamers into gamers?
    0:11:09 It’s a bit of a hybrid between traditional video games and that live, crowd-driven competitive
    0:11:10 event.
    0:11:11 It remains to be seen.
    0:11:17 I think, yes, from the perspective that you’re having an audience that may have never actually
    0:11:24 watched NBA 2K or FIFA, for example, any of these sports video games that are now exposed
    0:11:27 to that and might actually think it’s pretty cool.
    0:11:32 And it’ll be interesting how many of these NBA players, one, how many of them can build
    0:11:38 large eSports followings and then, two, if their eSports followings actually end up being
    0:11:42 larger than their real-life following, I think that would be a real success story.
    0:11:44 It’s a brave new world.
    0:11:46 Let’s turn to live streaming.
    0:11:47 Absolutely.
    0:11:52 So the analytics site, Sully Nome, actually just released a couple of data insights.
    0:11:56 The high-level headline is that Twitch is essentially having the biggest month of its
    0:11:57 history.
    0:12:02 Livecast hours also grew by 35% over the last week compared to the average of the prior
    0:12:03 three weeks.
    0:12:10 And Sunday ended up being an all-time record breaker, where 47.7 million hours watched.
    0:12:13 Why this rise in live streaming?
    0:12:17 Part of that could be due to the fact that you have people that are checking out live
    0:12:19 streaming for the first time.
    0:12:26 Another interesting nugget was that downloads of the Twitch app increased by about 30% just
    0:12:32 in the US alone between the weeks of March 8th and March 15th, so you have a lot of
    0:12:34 people that are checking it out for the first time.
    0:12:40 I think a second thing is that live streaming is unique as a media format and that it combines
    0:12:45 the reach of a public broadcast with the intimacy of a small group community.
    0:12:51 And what I mean by that is essentially, as a live streamer, you can reach hundreds of
    0:12:53 millions of people with a single live stream.
    0:12:59 So it is a public broadcast media just like TV or the radio.
    0:13:03 But because of the fact that it’s interactive, your viewers can type at you and you can have
    0:13:07 a conversation with them and you can adapt what you’re doing in real time to what your
    0:13:09 viewers demand.
    0:13:11 It feels like a smaller group conversation.
    0:13:14 And you can monetize in real time, right?
    0:13:15 That’s right.
    0:13:18 People tip in real time if you’re doing something that’s very popular, that if you’ve answered
    0:13:24 a request, people can subscribe to your channel and the subscriptions cost money anywhere from
    0:13:26 a couple of dollars that way more.
    0:13:31 So it’s interesting as both an engagement and a monetization model for influencers these
    0:13:32 days.
    0:13:39 So it’s kind of a hybrid of YouTube and TikTok in that you can amass this online following,
    0:13:42 you can be streaming live, but you can also be monetizing instantly.
    0:13:43 That’s right.
    0:13:48 On YouTube and TikTok, for example, you produce content and then you upload it in any
    0:13:51 way that you have to wait and see what happens and you’re not actually getting that much
    0:13:53 in terms of real time feedback.
    0:13:59 TikTok is slightly more real time than YouTube, simply because the videos are shorter and
    0:14:03 people can like and comment very quickly after you upload something.
    0:14:07 But live streaming platforms are unique in the sense that you are literally performing
    0:14:12 in real time for a live audience and you’re getting the feedback just as if you’re a stage
    0:14:17 performer in real life in real time, given either clapping or throwing tomatoes at you,
    0:14:19 or digital tomatoes.
    0:14:20 That’s right.
    0:14:24 And I think that’s one of the things that makes live streaming work so well right now
    0:14:26 in COVID times.
    0:14:31 It’s because people are actually able to get a sense of community online through live
    0:14:35 streaming that may otherwise be hard to find in the real world because we can’t get together
    0:14:37 in large groups anymore, right?
    0:14:41 Like you can’t go to church, you can’t go to school, you’re not at work.
    0:14:45 So a lot of the communities that people are ordinarily members of I think have sort of
    0:14:50 fallen by the wayside and Twitch has been able to provide that sense of community for
    0:14:51 a lot of its viewers.
    0:14:58 As opposed to passively binging Netflix, people want this more interactive way of being social
    0:15:00 with their friends and family.
    0:15:04 I mean, speaking of relationships, it’s a bit of a personal story, but video games actually
    0:15:08 saved my marriage and totally not getting here.
    0:15:10 How so?
    0:15:15 So when my wife Jen and I first started dating, we were actually long distance for the first
    0:15:16 year of our relationship.
    0:15:21 I was in San Francisco, she was in New York, so we actually met at a New York City to get
    0:15:27 together and then I had to fly out literally two days from afterwards and it was really
    0:15:28 tough.
    0:15:31 We didn’t know each other that well, but we started playing an online game called League
    0:15:35 of Legends together and that completely saved the relationship.
    0:15:39 When we didn’t feel like talking about serious things, we could just play the game and there
    0:15:45 were enough sort of highs and lows and moments of tension and drama that we also got to know
    0:15:47 each other better as we played together.
    0:15:48 I love that story.
    0:15:51 Yeah, so who says you can’t find love in video games, right?
    0:15:53 So you’ve been married 10 years now.
    0:15:56 Are you still playing League of Legends together?
    0:15:57 We still are.
    0:16:02 It’s one of the mainstays of our relationship actually, so a light-hearted way to spend time
    0:16:06 and I imagine that’s what a lot of people these days are doing in quarantine as well.
    0:16:11 You know, if you’re in a small apartment or a house with members of a larger extended
    0:16:16 family, there’s only some sort of conversation you can have before fights start breaking
    0:16:22 out, so maybe you break out the Xbox, play some mobile games, play some party games and
    0:16:26 it helps generally improve the quality of life in the house.
    0:16:29 I think there’s definitely a social dynamic at play.
    0:16:35 A lot of people aren’t necessarily comfortable FaceTiming or video chatting and seeing their
    0:16:38 own face reflected as they talk to family members.
    0:16:41 So I think gaming provides this distraction.
    0:16:45 You’re doing something else while you’re connecting with your family or friends.
    0:16:50 Yeah, I think one of the best ways I’ve heard it described by a live streamer is actually
    0:16:57 that games can switch back and forth between foreground and background activity, so you’re
    0:17:01 not really thinking too hard about the game, but you’re actively conversing and you might
    0:17:06 actually be talking about something that’s like very serious, but then you can just switch
    0:17:09 the game back into the foreground and you both concentrate on the activity.
    0:17:15 And so it provides activity to fill in the gaps that are very natural in conversations
    0:17:19 and it doesn’t feel like just long periods of silence if you don’t have anything to say
    0:17:20 to each other.
    0:17:23 Yeah, I think that’s something we’re all familiar with.
    0:17:28 The point is social distancing, quarantine, it’s lonely and I think a lot of people are
    0:17:31 rediscovering gaming as a way to connect with others.
    0:17:36 So after we weather this crisis, what will this mean for the games industry?
    0:17:37 What is the bigger picture?
    0:17:43 The bigger picture here is that gaming is unique as a media type and that it’s real
    0:17:45 time and it’s fundamentally social.
    0:17:50 When you’re playing a game, you’re partaking in an immersive activity with someone else.
    0:17:54 And so I think that’s one of the reasons why gaming has seen such explosive growth since
    0:17:56 the start of coronavirus.
    0:18:01 And so I think games and live streaming are offering a lot of the social connections that
    0:18:05 people are missing as they’re staying at home these days and I think that will only
    0:18:06 continue over time.
    0:18:12 So once this crisis is over, do you expect these new gamers to stick around?
    0:18:13 I hope so.
    0:18:17 It’s easier than ever to get into games today with just so many different platforms that
    0:18:18 you can play on.
    0:18:22 If you have a console or a gaming PC, that’s great but you don’t need one.
    0:18:27 You can also play phenomenal, triple-way quality games in your mobile phones these days.
    0:18:32 And so the barrier is the entry for people coming back in the game to discovering games
    0:18:34 for the first time is lower than ever.
    0:18:35 Great.
    0:18:37 Well, John, thank you so much for joining us on the A16Z podcast.
    0:18:38 It’s been a pleasure.
    0:18:39 Thanks for taking the time.

    Since social distancing measures were first put in place, time spent gaming has gone up—way up. According to a recent report by Verizon, video game usage in the U.S. has risen 75 percent during peak hours. The “stay at home” movement has given way to an upswell of new and returning gamers—as well as new challenges, as online platforms struggle to keep up with the surge.

    In this episode, a16z partner Jon Lai joins host Lauren Murrow to talk about how game developers are grappling with skyrocketing numbers, why this may be an inflection point for VR, the surprising transition of professional sports into esports, and why live-streaming is having its moment.
