  • Sam Altman on How to Start a Startup in the AI Era: Exponentials, Chaos, Compute Bottlenecks, and the Fight Against AI Authoritarianism

    More than a decade after his famous Stanford lectures on how to start a startup, Sam Altman sits down for a wide-ranging conversation about what has changed. His answer: almost everything. A ten-week-old startup today can ship what used to take a year, the ground is shifting faster than at any point in his career, and the defining fight of the moment is whether AI leads to broadly shared abundance or a new kind of authoritarianism. Along the way he covers the ChatGPT launch week, the decision to kill Sora to feed coding agents, his 28-country world tour, what Jony Ive taught him about design, and why he deleted TikTok.

    TLDW

    Altman argues that startups have their biggest edge when the ground is shifting, and it has never shifted faster, yet most founders are settling for “AI agents for enterprise vertical X” instead of building for the models of two years from now. He explains his core belief system (trust the exponential, in people, companies, and models), why operating in chaos is learnable but not teachable, and how a clear mission plus deep problem understanding tells you what to build. He walks through OpenAI’s bets: courting suppliers by showing them the research roadmap, the joint stock corporation as the industrial revolution’s real invention, why compute (transistors, then electrons) is the bottleneck, and why the world needs more focus on data centers that can build more data centers. He retells the ChatGPT million-user week, the Codex comeback against Claude Code, killing robotics for GPT-3 and Sora for coding agents, the coming third wave of persistent agents, real versus fake trends, Jony Ive’s problem-first design process, his TikTok addiction experiment, hiring fast movers and promoting executives internally, Masayoshi Son’s conviction, and why everyone will be busier, not idler, after superintelligence. The current fight, as he frames it: liberty versus a single machine god.

    Thoughts

    The most useful idea in this conversation is an arbitrage argument. Altman says the market has not priced in that scaling laws will continue, the same way it never fully priced in high-growth young founders. The practical move follows directly: start building the thing that is not economical this month but will be trivial in two years. Almost nobody does this. The gravitational pull toward “apply today’s agents to the easy wins” is exactly the kind of consensus behavior that produces competitive, low-upside companies. He is telling founders, fairly explicitly, that free money is sitting on the table for anyone willing to plan against the curve instead of the current model card.

    His line about algorithms versus data centers deserves more attention than it will get. Everyone in AI is obsessed with recursive self-improvement in software, algorithms that create better algorithms. Altman flips it into the physical world: data centers that can build more data centers, robot fleets powered by a data center’s own thinking, compounding infrastructure. Whether or not you buy the vision, it explains OpenAI’s capital allocation better than any press release. The company is behaving as if the constraint on intelligence is matter and energy, not ideas, and his blunt bottleneck ranking (transistors, then electrons) says the same thing in three words.

    The liberty versus safety framing is doing a lot of strategic work. Positioning the alternative to open access as “one single model as the machine god” makes decentralization sound like the only humane option, and it conveniently aligns with OpenAI’s commercial interest in putting its product in every hand on earth. That said, the underlying claim, that trading liberty for safety has been a long-term net loss every time humanity has tried it, is a serious argument, and he pairs it with a genuinely striking admission: one of the AI risks he worries about most is authoritarianism, a small number of people or companies deciding they need to control the world. Readers can decide how comfortably that sits alongside a trillion-dollar infrastructure buildout controlled by a small number of companies.

    There is also a quieter thread here about what can and cannot be transferred between people. Chaos tolerance is only learnable through reps. Strengths that come supernaturally cannot be explained, only observed, the way gamers study pros. Jony Ive’s leap from deep problem study to a fully formed idea is, by Altman’s own account, a step he does not understand. For a man whose company sells the automation of cognition, he keeps a surprisingly long list of things that resist being taught. That list is arguably a map of what stays valuable for humans, alongside his other candidate: betting with evolutionary biology, cooking, adventure, eating together.

    Finally, the TikTok confession is the most honest moment in the interview. The man building the next attention-capable device deliberately addicted himself to TikTok as product research, loved it, lost a Saturday afternoon to it, and deleted it because self-control was not enough. He then says, in nearly the same breath, that people will misuse the devices OpenAI ships with Jony Ive and that lives will get worse in ways we cannot imagine, and we will adapt. That is the entire ethical tension of consumer AI compressed into one anecdote, delivered by the person best positioned to do something about it.

    Key Takeaways

    • The biggest shift since the original How to Start a Startup lectures is what a tiny team can now do and how fast. A two-week-old startup Altman met had rebuilt an entire office productivity suite designed for AI as a first-class user, work he estimates would recently have taken a year.
    • Startups have their biggest inherent edge when the ground is shifting the most and when costs and cycle times are collapsing, which is happening in many places at once right now.
    • Most founders are building “AI agents for enterprise vertical X.” It will often work, but Altman doubts those will be the defining companies of the era, and he is surprised more people are not attacking crazy ambitious problems with the completely new toolset.
    • The single most important thing he would tell founders today: truly internalize that scaling laws will continue, and start working now on things that require smarter or cheaper models than exist this month.
    • His unifying belief system is a great trust in exponentials, whether in people, companies, or models. The market has still not adapted to either the founder version or the model version, which means there is free money in betting on both.
    • Operating in chaos is only learnable through reps, not teachable. Young founders’ key weakness is that they have not yet reached emotional peace with things constantly going wrong, and they pay for that education in unforced errors.
    • At YC office hours he could always identify new founders by their emotional state when describing problems. Veterans have survived enough company-killing events to stay calm.
    • The opposite of a bad experience is not a good experience, it is no experience. Borrowing Naval Ravikant’s image, a fast-forward button for your life would just end it, so be grateful for the bad days too.
    • A clear mission plus a deep understanding of the problem does most of the work of deciding what to build. OpenAI’s mission is to make intelligence extremely abundant, cheap, and broadly distributed.
    • One of the AI risks Altman worries about most right now is AI authoritarianism: a small number of people or companies thinking they need to control the world.
    • He frames the fight of the current moment as liberty versus a single model as machine god. Every time humanity has traded liberty for safety it has been a long-term net loss, so OpenAI’s answer is to empower people, with guardrails, and let society decide how to use the technology.
    • The key inputs to abundant intelligence (energy, chips, robots, data centers) are also exactly what you want immediately after you have abundant intelligence, because ideas still have to become things in the physical world.
    • Asked for the biggest bottleneck to continued scaling, his answer is four words: transistors, and then electrons, in that order.
    • Keeping suppliers on OpenAI’s timeline means showing them the upcoming models and research so they believe in the mission, then aligning their incentives with yours as much as possible. Orders alone get deprioritized.
    • Altman argues the most important invention of the industrial revolution was the joint stock corporation itself: incentive alignment, liability protection, and pooled capital let strangers cooperate beyond what any family business could do, and the curve of human welfare bent visibly after it appeared.
    • The chart people should study more is the fall of extreme poverty over the last hundred years, which he attributes to the ridiculous overperformance of capitalism.
    • He plans forward from the present guided by a small number of strongly held convictions about the future, rather than planning backward from a rigid 20-year vision. People with too many beliefs about the future end up chasing trends, like space companies turning into AI companies.
    • For over a decade the critical path to abundant intelligence has been clear enough that he never questioned the goal. Feeling close to superintelligence is the first thing that has made him think about what comes next (eventually, the ranch).
    • Get on planes in marginal situations. He recently took a very inconvenient two-overnight trip he cannot talk about, with a new baby at home, and it worked out. People systematically overestimate the risk of taking action.
    • The 2023 world tour (28 countries in 35 days, on Brian Chesky’s advice) happened because world leaders were nervous enough after GPT-4 that he sensed things were about to go very badly if nobody showed up to talk.
    • Simply getting people to explain out loud why they think a decision is high risk or low risk usually breaks through their intellectual blocks, because people are usually wrong in one direction or the other.
    • Corporate careers catastrophically suppress ambition. New founders arrive having always had a boss, punished since childhood for thinking too big; nearly every culture has a phrase like tall poppy syndrome for it. The cure is small repeated wins.
    • OpenAI’s superpower, in his telling, was principled conviction on something obvious that nobody else believed, plus assembling the pieces and talent around it. He was more worried they were drinking their own Kool-Aid than that everyone else was wrong.
    • By 2019 or 2020, Google should have run away with AI. OpenAI’s continued existence is, like AWS’s seven competition-free years, a business miracle that says something about how sclerotic big companies get.
    • On ChatGPT’s fifth day it crossed a million users. Researchers kept calling it a flash in the pan, but YC pattern recognition told him organic growth like that meant the quiet life was over: “we were being shot out of a cannon.”
    • There have been two giant AI form factors so far, chatbots and coding agents, and coding agents are going totally nuts. The third wave, coming soon: persistent agents that act as chiefs of staff, co-workers, and colleagues.
    • Codex was a deliberate kamikaze mission: OpenAI was way behind Claude Code, consensus said you never win against momentum, but coding mattered too much to recursive self-improvement to concede. The team pulled off what he calls a very rare thing in business history.
    • OpenAI repeatedly kills good things to make the best thing work better: robotics died for GPT-3, and Sora and the browser were shut down to pour compute and people into coding agents. Sora would have been super successful; it was still the right call.
    • Killing a project people love is never one meeting. It is a gradual realization that the compute, people, and product direction have a more important use, and people accept it because they understand the mission and the stakes.
    • There is too much focus on algorithms that create better algorithms and not enough on data centers that can create more data centers. With robots and an automated supply chain, a data center’s thinking power could drive the construction of its own copies.
    • The big idea is the easy part and carries none of the glory. Almost all of his time goes into execution: financing fabs, assembling chip design teams, getting the machinery of many companies to work together. Grinding.
    • Jony Ive taught him that really great design is way more about understanding the problem than the flash of insight. Ive studies a problem exhaustively (typefaces, engine sounds, materials, whole books of exploration) before letting himself think about solutions.
    • Altman calls the iPhone the greatest piece of technology humanity has yet made, but he no longer loves his relationship with it. He turned off nearly all notifications and deleted TikTok after an intentional research addiction got away from him.
    • Double down on strengths. The obsession with fixing weaknesses you will never be good at is a huge trap. And the meme that you can only hire for what you deeply understand is false: he cannot design, but thirty minutes with Jony Ive makes greatness obvious.
    • Organizational speed is about 90 percent determined by who you put in leadership roles. He evaluates everyone for whether they are a fast mover, and thinks executives should usually be promoted internally rather than hired from outside.
    • Real trends versus fake trends: a fake trend (VR for years) gets bought, half-loved, and shelved. A real trend (ChatGPT) becomes a persistent part of how people design their lives. The test is deep, enduring, daily use.
    • Technology keeps promising leisure and delivering ambition. Expectations rise, status is relative, and people want to be useful to each other, so everyone will be busier than expected after superintelligence, still complaining, secretly happy.
    • What stays valuable post-AI is what evolution built us for: cooking and eating together, adventure, quests, showing love through effort. Betting against evolutionary biology is usually a bad bet.
    • His last big failure of ambition: badly undershooting compute investment because he got psyched out by financial markets. He considers it a clear mistake he will not repeat.
    • The most painful thing in his last year had nothing to do with OpenAI: having kids while working this hard means missing pieces of a one-time thing, even as a present dad who does nothing but work and family.
    • A startup today still mostly looks like a startup of ten years ago because that is the received wisdom, and “using AI” usually just means using more Codex. Altman thinks it should look completely different, and only a few founders are trying.

    Detailed Summary

    The startup landscape has reset

    Ten years after his Stanford course, the biggest change is what a small team can do and how fast they can do it. A ten-week-old startup today looks nothing like one from 2016, and a startup that still looks like 2016 is in bad shape. What counts as a “hard startup” is changing so quickly that Altman admits he no longer has a perfect mental model for which things will be hard and valuable over a company’s lifetime: everyone says the physical world is where the value is because software is going free, but robots will get good, and even rockets may stop being hard. His conclusion is that times like this are precisely when startups have the biggest edge, because incumbency matters least when the ground is moving. His frustration is that so few founders act on it, defaulting to safe agent-wrapper plays instead of attacking the crazy thing with the new tools and planning for the models of two and four years from now.

    Exponentials as a belief system

    Asked whether years of mentally plotting founders’ growth trajectories prepared him to believe in model scaling curves, Altman generalizes: the common thread is trust in exponentials, whether the subject is a person, a company, or a model. It is evidently hard for people to hold this belief, which is why there is still free money in backing high-growth young founders, and why the market still underprices continued model progress. If he were still advising founders, getting them to wrap their heads around this would be his top priority, because it licenses the most profitable behavior available: building today what only tomorrow’s models make economical.

    Chaos, resilience, and the founder’s education

    Operating amid chaos, trusting you will figure it out, and not treating each crisis as the thing that kills you is, in Altman’s view, learnable only through repetition, never teachable. This is the real weakness of young founders: no career has given them emotional peace with constant malfunction, so they buy it with pain and unforced errors. At YC office hours he could tell a first-batch founder from a two-year veteran purely by emotional register. His reframe for enduring the bad stretches comes from Naval Ravikant: the opposite of a bad experience is not a good experience but no experience, and a fast-forward button for your life would simply end it. Since something will always be going wrong, gratitude for the bad days is a load-bearing skill.

    Mission, liberty, and the machine god question

    OpenAI decides what to tackle by combining a clear mission (make AI abundant, cheap, powerful, and in everyone’s hands) with a deep understanding of what blocks it: chips, energy, data centers, robots. Altman explicitly does not want OpenAI building every vertical on top of its own platform; he says a decentralized economy matters and that one of the AI risks he worries about most is AI authoritarianism. He frames today’s fight bluntly. Alignment and jobs remain unsolved, but the live question is whether the very real safety and economic concerns get used to justify one single model as machine god, or whether the technology is put messily into everyone’s hands. His answer rests on a historical claim: every time humanity has traded liberty for safety, it has been a long-term net loss. He also notes the elegant, or perhaps merely obvious, fact that the inputs to abundant intelligence (energy and robots) are the same things you most want right after you have it, since intelligence still has to manipulate matter.

    Incentives, suppliers, and the joint stock corporation

    Keeping the rest of the world on OpenAI’s timeline means talking to suppliers constantly and showing them the upcoming models and research until they believe, then aligning incentives as tightly as possible; a purchase order alone gets shuffled behind other priorities. Riffing on Charlie Munger’s line about always underestimating the power of incentives, Altman offers a revisionist history of the industrial revolution: the important invention was not any machine but the joint stock corporation, which added incentive alignment, liability protection, and capital pooling to a world of trust-based family businesses, enabling speculative technology development and serious financial systems. Draw all of human history and mark where the company was invented, and the curve changes shape. The fall of extreme poverty over the last century is, to him, the chart people should look at most, and the ridiculous overperformance of capitalism explains it. He pushes back gently on the host’s sociopath-CEO theory: the best CEOs he knows are high-ego, not sociopathic, driven by seeing how good they can get at the most interesting strategic game.

    The world tour and getting on planes

    Three years ago, right after GPT-4, world leaders were asking whether they needed to take control and shut things down. Sensing storm clouds, and advised by Brian Chesky, who had done an eight-city version for Airbnb, Altman compressed what could have been endless one-off trips into 28 countries in 35 days, living on a plane. Because the hops were mostly an hour at a time, jet lag was mild but exhaustion was total; near the end he began half-dreaming that he was waking in his childhood bed, which he read as a deep it-is-time-to-go-home signal. The tour lowered global tensions and taught him to batch international travel into 7 to 10 day chunks once or twice a year. The broader lesson he draws: people wildly overestimate the risk of most actions. Buying call options on Robinhood is risky; getting on a plane in a marginal situation is usually not. His recent unspeakable example: an inconvenient two-overnight trip with a new baby at home, taken reluctantly, that worked out. Codex is the example he can talk about: asking a team to win a category Claude Code already owned looked like a fool’s errand, and it produced what he calls one of the rare comebacks in business history, now the tool most of the best coders he knows use.

    From research lab to product company in five days

    OpenAI began as roughly a dozen people in Greg Brockman’s apartment saying “so here we are, what are we going to do? We should get a whiteboard.” It took a couple of years to find its groove. Running the research lab was, in Altman’s description, the coolest, least stressful, most intellectually satisfying job imaginable: a front-row seat to the most important work of the last century. He knew a product moment would eventually come and successfully deluded himself into acting like it would not. Then ChatGPT launched. Each day traffic peaked higher while researchers dismissed it as a PR flash in the pan, but he had seen enough organic growth curves at YC to recognize the spectral signature. On day five it crossed a million users and he went home and told Ollie: you have no idea how bad this is, our nice quiet life is about to go through a cannon. Running the product company shares almost nothing with running the lab; what YC did prepare him for was recognizing the moment. The pattern is now repeating: chatbots were wave one, coding agents are wave two and going nuts, and persistent agents (chiefs of staff, co-workers, colleagues) are the imminent third wave.

    Killing good things, compute, and self-replicating data centers

    The easy discipline is killing what is not working once you run out of ideas. The hard one is killing things that work: when GPT-3 took off, OpenAI shut down beloved robotics work; when coding agents took off, it shut down Sora and the browser, not because Sora would have failed (Altman says it would have been super successful) but because the compute and people had a more important use. Those calls are gradual realizations, not single meetings, and people accept them because the mission and stakes are understood. On infrastructure, which may become the biggest project of all time, OpenAI will not vertically integrate everything: chip design and model design belong together, electron production is a commodity. But he sees a deep imbalance between the field’s obsession with recursive algorithmic improvement and the neglected idea of data centers that can build more data centers, where a data center’s own intelligence drives robot fleets that construct its copies. Nearly all his time goes into the gritty execution behind this: financing fabs, assembling teams, making supply chains function, work he describes as grinding with none of the glory of big thoughts. His confessed failure of ambition is undershooting compute because financial markets psyched him out.

    Design, Jony Ive, and the device problem

    Working with Jony Ive taught Altman that great design is mostly deep problem understanding, not a flash of insight. Ive studies everything (the history of motorsport, cabin typefaces, engine sounds across decades) and writes literal books of exploration before allowing himself to think about solutions; the middle step, where understanding becomes a fully formed novel idea all at once, remains a mystery even up close. Altman calls the iPhone humanity’s greatest piece of technology while admitting he no longer loves his relationship with it: notifications are off for almost everything, including messaging apps, which he calls a big life upgrade. While building the Sora app he deliberately addicted himself to TikTok as research, loved it, believed he could control it, lost an hour, then a three-hour Saturday afternoon, briefly regained control, and finally deleted it. He is sure the devices OpenAI makes will be beautiful and empowering, and equally sure people will misuse them in ways that make lives worse before we adapt. He does not claim design as his own skill; he claims knowing greatness when he talks to it for thirty minutes, and rejects the meme that you can only hire in domains you deeply understand.

    People, speed, trends, and what stays human

    Organizational pace is 90 percent the people in leadership roles; management systems are rounding error. He sorts leaders into fast movers and slow movers, prefers promoting executives internally, and when hiring externally leans on long conversations, heavy reference checks, and casual trial collaboration. Raising ambition in people broken by corporate life takes time, and the mechanism is small repeated wins, not inspirational speeches, which he does not do. His real-versus-fake trend test, absorbed from mountains of YC data: fake trends (VR for many years) get purchased and shelved; real trends get woven into daily life the way ChatGPT has. Skills that come supernaturally to someone cannot be taught by explanation, only absorbed by studying the person in action, the way CS:GO players study pros. On the future of work, he expects the leisure promise to break the way it always has: expectations rise, status is relative, the desire to be useful persists, so a post-superintelligence world is a busier one, still complaining, secretly happy. What endures is what evolution shaped: cooking for people, eating together, adventure, quests. Betting against evolutionary biology is usually a bad bet. His own next thing, once broadly shared prosperity from superintelligence is on the glide path: eventually, the ranch. And the most painful thing of his year was not corporate at all, but the arithmetic of new fatherhood against the singularity’s work hours.

  • Paul Graham and Jessica Livingston on Resilience at Y Combinator: Founder Mode, Cockroaches, Sticking to Your North Star, and Why AI and Climate Keep Them Up at Night

    For the very first episode of Disaster Proof, the conversation goes to a garage in Palo Alto to sit down with Paul Graham and Jessica Livingston, the founders of Y Combinator. They have backed thousands of companies, including many now working in the resilience space, and the discussion covers what makes startups durable, why adaptability beats expertise, how Brian Chesky stumbled into founder mode at Airbnb, why the best ideas grow out of a founder’s own life, and the two specific risks (AI and climate change) that Paul says are the only ones he treats as genuinely game over. You can watch the full conversation on YouTube here.

    TLDW

    Paul Graham and Jessica Livingston explain why constant change favors young, flexible founders, and why Y Combinator picks people over ideas precisely so its judgment never goes obsolete. They unpack adaptability as the trait they hunt for in interviews, the “founder mode” story behind Brian Chesky steering Airbnb through COVID, and the 2008 strategy of funding tough, close-to-revenue “cockroaches.” Paul argues a company survives turbulence by sticking to a North Star instead of acting as a weather vane in shifting moral fashions, using the biosphere tree that collapses without wind as his metaphor for resilience. They turn to climate and energy as the next great market, the difficulty of selling into utilities, the Gridware success story, fusion no longer being thirty years away, and the trap of guilt-based business models versus the reliable assumption that users are selfish, greedy, and lazy. The personal-resilience half covers surviving Twitter mobs, Paul’s obsessive essay process, raising kids by indulging curiosity and picking your battles, prepping by living among reasonable people, political polarization, and why AI and climate are the two things that keep them up at night.

    Thoughts

    The most useful idea in this conversation is also the most counterintuitive: a world that feels like it is ending is structurally good for the people least invested in how it used to work. Paul’s point to terrified founders is that change is only a threat if you have sunk costs in the old order. A young founder has been doing the current plan for two weeks, so a step-function shift in the landscape costs them almost nothing to abandon. The incumbents with elaborate machinery and a decade of assumptions are the ones who should be afraid. That reframes resilience away from defense and toward optionality. The resilient party is not the one with the thickest walls, it is the one with the least to unlearn.

    The founder mode discussion is worth sitting with because it quietly overturns a generation of management orthodoxy. The old rule was that a good CEO hires executives and gets out of their way, and that getting into the details is micromanaging. Brian Chesky’s COVID experience at Airbnb broke that rule under maximum pressure. With bankruptcy on the table and a travel company facing a world that stopped traveling, he went line by line through the business and told people what good looked like, then gave them freedom to execute against that standard while still demanding visibility. The interesting nuance is the permission structure. A crisis granted Chesky the license to be involved that normal operating conditions would have framed as meddling. The lesson is not “always be in the weeds,” it is that the founder’s deep understanding and disproportionate caring are assets you are wasting if you reflexively delegate them away.

    Paul’s North Star argument is the part most likely to age well. His claim is that companies fail at resilience when they behave like weather vanes, swinging with each gust of public moral fashion. He pairs it with the biosphere tree that grows weak and topples because it was never exposed to wind. Both metaphors point at the same thing: resilience is built by surviving stress while holding your shape, not by avoiding stress and not by reshaping yourself to whatever the crowd currently rewards. The carbon-credit companies he mentions are the cautionary case. They built their entire premise on a fashion (customer guilt about carbon) and went out of business when the wind changed direction. Durable businesses convert a permanent human motive into value, which is why he prefers the brutally honest assumption that the user is selfish, greedy, and lazy, and that your job is to build something that produces good outcomes anyway.

    The climate and energy section reframes a worthy cause as a market-timing bet rather than a moral appeal, and that is the more powerful version. The comparison to fintech in 2008 is the tell. Banking technology was a sleepy, unglamorous sector that venture investors avoided until a crisis cracked it open and made it one of the best categories of the following decade. The argument is that energy and the physical world are sitting at a similar precipice, made newly viable because hardware is starting to behave more like software (order components, assemble, do not build everything from scratch) and because AI’s hunger for power has made energy the binding constraint on the whole industry. The Gridware story crystallizes the founder lesson underneath all of it. The best founder for a hard physical problem was a lineman who worked the electric lines and lived through the fires. The idea grew authentically out of his life, which is the same pattern Jessica keeps returning to and the same advice they give for raising kids.

    Finally, the personal-resilience material is more practical than it first appears. Paul’s method for surviving a Twitter mob is pattern recognition: once it has happened twenty times, you know it ends in two days and they move on to the next target, so you wait it out instead of capitulating. His essay process is the same conviction-building engine applied to ideas. He goes sentence by sentence until there is no false statement left to attack, which is why his challenge to angry readers (“point out the incorrect statement”) almost never gets answered. The throughline across the company advice, the parenting advice, and the personal advice is identical. You build durable conviction not by sitting in a room thinking, but by working the problem until it is right, then refusing to be blown off course by people who never actually engaged with the substance.

    Key Takeaways

    • Experts are frequently wrong because they are experts in a previous version of the world, so Paul deliberately avoids permanent beliefs about the current state of technology.
    • Y Combinator picks startups by picking founders, not ideas, because the founders know more about the ideas than the investors do.
    • Living in England and visiting for each batch lets Paul arrive every quarter expecting the world to be different, which keeps his mind open instead of anchored.
    • A world of constant change feels bad but is actually good for a young, flexible founder who has only been on the current plan for two weeks and can switch easily.
    • Vibe coding went from kind-of-works to reliably works, and even experienced programmers now generate huge volumes of code with AI.
    • There is still a software business even with AI, because someone has to know what to tell the AI to write, and no company is going to write its own database from scratch.
    • The scenario Paul worries about is model companies spinning up agents to start all the startups themselves, removing the need for human founders.
    • The founder traits Jessica looks for are unchanged over the years: determined, flexible-minded, and willing to adapt.
    • In interviews you can spot rigid founders because they answer the question they prepared rather than the one they were asked, and the gears visibly grind when you redirect them.
    • A good adaptability signal is a founder who says “I haven’t thought about that, but here is how I would think about it” instead of freezing.
    • Founder mode, the term, came from Brian Chesky’s experience steering Airbnb through COVID, when bankruptcy was openly discussed in board meetings.
    • Ken Chenault, the former American Express CEO on Airbnb’s board, told Chesky the moment was ten times worse than 9/11 and could define the company.
    • Founder mode meant Chesky understood every line item, told people what good looked like, then gave them freedom to execute while still wanting to see it.
    • Founders see through the fog because they understand the company better than anyone and they care more than anyone, and combining understanding with caring lets them see more.

    Detailed Summary

    Staying an expert when the world keeps changing

    The conversation opens on Paul Graham’s essay “How to Be an Expert in a Changing World,” whose core point is that experts are often wrong because they are experts in a previous version of the world. Asked how he keeps his own beliefs from going obsolete when the landscape can shift in ninety days, Paul says he focuses on people. YC picks founders rather than ideas because the founders know the ideas better than any investor could. He deliberately holds no permanent beliefs about the current state of technology, and the rhythm of flying in from England for each batch helps: he arrives every quarter already expecting everything to be different. One quarter the story is everyone training open-source models, the next quarter it is Claude code and nobody bothers with open-source models because the frontier versions are better anyway. He comes in with a completely open mind. Jessica and Paul note that today’s founders are more frightened, asking what is even still true, but the message Paul gives them is that constant change favors the young and flexible. If you have only been executing a plan for two weeks, a disruption costs you nothing; you just switch.

    What adaptability looks like in a founder

    Jessica describes the founders she funds as determined, flexible-minded, and willing to adapt, and calls adaptability a key trait always, but especially in uncertain times. In interviews, the rigid applicants reveal themselves by answering the question they planned to answer rather than the one they were asked, and you can almost hear the gears grind when you redirect them. Paul does not let that slide; if they dodge, he just asks again. The positive signal is a founder who, faced with a question they have not considered, says “here is how I would think about it” and reasons live. Both point out that YC itself had to adapt, and that the company they funded the interviewer’s startup as in 2009 looked very different by the end. They funded him in May 2009, in the thick of the financial crisis, after he had quit his job in August 2008 and briefly felt he had made a terrible mistake.

    Founder mode and seeing through the fog

    Paul points to Brian Chesky as the defining example of weathering disaster, a story he explored on This Week in Startups. When COVID hit a travel company like Airbnb, the word bankruptcy was being used in board meetings, and Ken Chenault, the former American Express CEO on the board, warned it was ten times worse than 9/11. Chesky went into what would later be named founder mode, getting into every line item, understanding exactly what was needed, telling people what good looked like, and then giving them freedom to execute while still insisting on visibility. The crisis gave him permission to be the involved CEO he had always wanted to be, the kind of involvement that normal operating conditions would have labeled micromanaging. Paul argues founders see through fog that blinds everyone else for a simple, rational reason: they understand the company better than anyone because they have been there longest and thought of most of it, and they also care more than anyone. Combine deep understanding with deep caring and of course they see more.

    Cockroaches, the North Star, and the biosphere tree

    Returning to 2008, when YC was self-funded and unsure whether anyone would invest by March, they decided to keep going on the principle that it is always a good time to start a startup, but to fund people close to making money and very tough founders they called cockroaches, after the creatures that survive nuclear war. Airbnb was the ultimate cockroach. Paul frames YC’s longevity around two axioms (startups matter, founders are the most important ingredient) and around resilience built through stress. He tells the story of trees grown inside a biosphere that fell over because they were never exposed to wind, since being blown about is a necessary part of a tree becoming strong enough to support its own weight. YC has been blown around and is still standing, which is exactly what gave it practice. The companion idea is the North Star: you cannot move with fashion or act as a weather vane swinging with other people’s moral fashions, you have to hold your founding principles, which Paul eventually wrote down rather than let a 23-year-old new hire do it.

    Climate, energy, and selling into hard markets

    The interviewer’s own path (a curiosity about wildfire that grew from living in California, watching PG&E go bankrupt, a fire on his Mendocino property, volunteering as a firefighter) becomes the case for ideas that grow authentically out of a founder’s life. Climate is framed broadly as energy, the built environment, and transportation, essentially the physical world, and those are hard markets where the buyers are utilities, governments, real estate, and insurance. The advice is to find early adopters who decide quickly, which usually means not starting with a utility but with something like a single corporate campus that will say yes faster. Utilities, though, are under so much stress from wildfire liability, renewables, EV charging, and AI demand that they are increasingly willing to try new things. Gridware, founded by a former lineman who lived through major fires, is the proof point: backed by Sequoia, with PG&E as a major customer. Paul notes the second-biggest chunk of YC startups after AI is hard tech, not because software died but because building physical things is getting more possible, more like ordering and assembling components. Energy is the binding constraint on AI, fusion no longer feels thirty years away, and the bet is that energy and physical markets are where fintech was in 2008, about to be cracked open.

    Guilt versus greed as a business model

    On the question of whether climate companies should sell on guilt (recycle, pay more because it is sustainable), Paul is blunt that guilt is fragile because fashions change what you are supposed to feel guilty about. The carbon-credit companies thrived until buying carbon credits stopped being cool, then went out of business. A founder’s own concern for the world can drive great companies, but depending on a customer’s guilt is shallow. The durable move is to assume the user is selfish, greedy, and lazy, someone who just wants to eat pizza and watch Netflix, and to build something that produces good outcomes despite that. Clean power is the perfect example: nobody watching Netflix is upset that fusion powers their television, and if it is cheaper and more reliable, that is simply more Netflix and more money for pizza.

    Personal resilience, Twitter mobs, and the essay process

    On surviving public criticism, Paul’s method is pattern recognition: after twenty mobs you stop counting and know it will be over in two days when they move to the next topic, so you wait it out even though it genuinely feels miserable. Half of them are bots or people you would never talk to in real life, but the deeper point is that companies and people stay resilient by not succumbing to mobs and not becoming weather vanes for moral fashions. Conviction is built by working on an idea, not sitting in a room thinking about it, unless it is pure thought like math. His essays are the engine: he writes a version one, notices everything wrong, and fixes it sentence by sentence until there is no false statement left. He will read an entire book for a single sentence because he would be mortified to publish something false and, having no deadlines, has no excuse. That is why his standing challenge to angry readers, to point out one incorrect statement, almost never gets answered.

    Raising kids, prepping, and the things that keep them up at night

    Their parenting philosophy is to give kids confidence and a stable base, indulge curiosity, and encourage projects nobody assigned, like the living room overrun by one son’s Lego. They pick their battles: they put their foot down on cruelty but admit total defeat on food, devices, and screen time. Paul’s favorite question for anyone with an unusual experience is not “what was it like” but “how was it different than you expected,” which surfaces the genuinely novel detail, and the meta-version of that became the show’s recurring question to all guests. On prepping, they joke that living in the English countryside is itself a form of preparation, and that in turbulent times you should bet on an island full of reasonable people. The episode closes on what keeps them up at night: AI and climate change, the two things Paul treats as uniquely game over, illustrated by the prospect of the Gulf Stream reversing and leaving Europe, which sits as far north as Alaska, a frozen wasteland. Jessica notes her YC superhero name was Panic, and the conversation ends, after a detour through political polarization and a child who insisted for six months on being called SR-71 forecast 80 leaping leopard, on the admission that they manage screen time by being utterly defeated.
