  • Elad Gil on the AI Frontier: Compute Constraints, the Personal IPO, and Why Most AI Founders Should Sell in the Next 12 to 18 Months

    Elad Gil sat down with Tim Ferriss for a wide ranging conversation that pairs almost perfectly with his recent Substack post Random thoughts while gazing at the misty AI Frontier. Together, the podcast and the post lay out the cleanest framework I have seen for what is actually happening in AI right now: a Korean memory bottleneck capping every lab, a class wide personal IPO across the research community, the fastest revenue ramps in capitalist history, and a brutal dot com style culling that most founders do not yet want to admit is coming. Below is a complete breakdown.

    TLDW (Too Long, Didn’t Watch)

    Elad Gil argues that AI is producing the fastest revenue ramps in capitalist history while setting up the same brutal power law that wiped out 99 percent of dot com companies. OpenAI and Anthropic each sit at roughly 0.1 percent of US GDP today, on a path to 1 percent of GDP run rate by end of 2026, which is insanely fast by any historical standard. The current ceiling on capabilities is not chips but Korean high bandwidth memory, and that constraint will likely hold all major labs roughly comparable in capability through 2028. Talent has just experienced a class wide personal IPO via Meta led bidding, with packages running tens to hundreds of millions per researcher. Most AI companies should consider exiting in the next 12 to 18 months while the tide is high. Right now consensus is correct. Save the contrarianism for later.

    Key Takeaways

    • OpenAI and Anthropic are each at roughly 0.1 percent of US GDP. With US GDP near 30 trillion dollars and each lab at a roughly 30 billion dollar revenue run rate, AI has gone from essentially zero to 0.25 to 0.5 percent of GDP in just a few years. If the labs hit 100 billion in run rate by year end 2026 (which many expect), AI hits 1 percent of GDP run rate inside a single year.
    • The AI personal IPO is real. 50 to a few hundred AI researchers across multiple companies just experienced a class wide IPO event due to Meta led bidding, with top packages reportedly tens to hundreds of millions per person. The closest historical analog is early crypto holders around 2017.
    • The bottleneck is Korean memory, not Nvidia chips. High bandwidth memory from Hynix, Samsung, Micron, and others is the binding constraint. Expected to hold roughly two years. After that, power and data center buildout become the next walls.
    • No lab can pull dramatically ahead before 2028. Because every lab is compute constrained on the same input, OpenAI, Anthropic, Google, xAI, and Meta should remain roughly comparable in capability through that window, absent an algorithmic breakthrough that stays inside one lab.
    • Compute is the new currency. Token budgets now define what an engineer can accomplish, what a company can spend, and what business models are viable. Some companies (neoclouds, Cursor) are effectively inference providers disguised as tools.
    • The dot com base rate is the AI base rate. Around 1,500 to 2,000 companies went public in the late 1990s internet cycle. A dozen or two survived. AI will likely look the same.
    • Most AI founders should consider selling in the next 12 to 18 months. If you are not in the durable handful, this is your value maximizing window. A handful of companies (OpenAI, Anthropic) should never sell.
    • Buyers are bigger than ever. One percent of a 3 trillion dollar market cap is 30 billion dollars. That math makes massive AI acquisitions trivial for hyperscalers, vertical incumbents, and adjacent giants.
    • Underrated exit path: merger of equals. Two private AI competitors destroying each other on price should consider just merging. PayPal and X.com did exactly this in the 1990s.
    • 91 percent of global AI private market cap sits in a 10 by 10 mile square. If you want to do AI, move to the Bay Area. Remote work for cluster industries is BS.
    • Want money? Ask for advice. Want advice? Ask for money. The inverse also works: offering useful advice frequently leads to inbound investment opportunities.
    • AI is selling units of labor, not software. The shift is from selling seats and tools to selling cognitive output. This is why Harvey can win in legal, where decades of legal SaaS failed.
    • AI eats closed loops first. Tasks that can be turned into testable closed loop systems (code, AI research) get automated fastest. Map jobs on a 2×2 of closed loop tightness vs economic value to see where AI hits soonest.
    • Headcount will flatten at later stage companies. Multiple late stage CEOs told Elad they will not do big AI layoffs but will simply stop growing headcount even as revenue grows 30 to 100 percent. Hidden layoffs are also hitting outsourcing firms in India and the Philippines first.
    • The Slop Age could be the golden era of AI plus humanity. AI produces useful slop at volume, humans desloppify it, leverage is high, and the work is fun. This window may close as AI gets superhuman.
    • Market first, team second (90 percent of the time). Great teams die in bad markets. The exception is when you meet someone truly exceptional at the very earliest stage.
    • The one belief framework. If your investment memo needs three core beliefs to be true, it is too complicated. Coinbase was an index on crypto. Stripe was an index on e-commerce. That was the entire memo.
    • The four year vest is a relic. It exists because in the 1970s companies actually went public in four years. Today the private window has stretched to 20 years and venture has eaten what used to be public market growth investing.
    • Boards are in-laws. You cannot fire investor board members. Take a worse price for a better board member, because as Naval Ravikant said, valuation is temporary, control is forever.
    • Right now, consensus is correct. Save the contrarianism. The smart move is to just buy more AI exposure rather than try to outsmart the obvious.
    • Distribution wins more than founders admit. Google paid hundreds of millions to push the toolbar. Facebook bought ads on people’s own names in Europe. TikTok spent billions on user acquisition. Allbirds (yes, the shoe company) just raised a convert to build a GPU farm.
    • Anti-AI sentiment will get worse before it gets better. Maine banned new data centers. There has been violence directed at AI leaders. Expect more political and activist backlash, especially as AI is blamed for harms it has not yet caused while its benefits are mismeasured.
    • Use AI as a cold reader. Elad uploads photos of founders to AI models with cold reading prompts and reports surprisingly accurate personality assessments based on micro features.

    Detailed Summary

    The Numbers Are Insane and Mostly Underappreciated

    The most stunning data point in either source is the GDP math. US GDP is roughly 30 trillion dollars. OpenAI and Anthropic are each rumored to be at roughly 30 billion dollars in revenue run rate, putting each one at 0.1 percent of US GDP. Add cloud AI revenue and the picture gets stranger: AI has grown from essentially zero to between 0.25 and 0.5 percent of GDP in only a few years. If the labs hit 100 billion in run rate by year end 2026, AI will be at roughly 1 percent of GDP run rate inside a single year. There is no historical analog for that pace. Elad notes that productivity gains from AI may end up mismeasured the way internet productivity was undercounted in the 2000s, which would have downstream consequences for regulation: AI gets blamed for the bad (job losses) and credited for none of the good (new jobs, education gains, healthcare improvements). His half joking aside is that the real ASI test may be the ability to actually measure AI’s economic impact.

    The AI Personal IPO

    The most underdiscussed phenomenon in AI right now, according to Elad, is what he calls a class wide personal IPO. When a company IPOs, a subset of employees become wealthy, lose focus, and either start companies, get into politics, fund passion projects, or check out. Meta started aggressively bidding for AI talent. Other major labs had to match. The result was 50 to a few hundred researchers, scattered across multiple labs, suddenly receiving compensation in the tens to hundreds of millions of dollars range. The only historical analog Elad can think of is early crypto holders around 2017. Some chunk of these newly wealthy researchers will redirect attention to AI for science, side projects, or quiet quitting. The aggregate field stays mission aligned, but the distribution of attention has shifted.

    The Korean Memory Bottleneck

    Every major AI lab today is building giant Nvidia clusters paired with high bandwidth memory primarily from Korean fabs and a few other suppliers. They run massive amounts of data through these clusters for months, and the output is, almost absurdly, a single flat file containing what amounts to a compressed version of human knowledge plus reasoning. Right now, the binding constraint on this whole stack is HBM memory from Hynix, Samsung, Micron, and others. Korean memory fab capacity has been below the capacity of every other piece of the system. Elad estimates this constraint persists for roughly two years. After that, the next walls are likely data center construction and power. The strategic implication is enormous. While memory constrains everyone, no single lab can buy 10x the compute of its rivals, so capabilities should stay roughly comparable across the major labs. Once that constraint lifts, possibly around 2028, one player could theoretically pull dramatically ahead, especially if AI assisted AI research closes a self improvement loop inside one lab.

    Compute Is the New Currency

    The blog post sharpens a framing that runs throughout the podcast: compute, denominated in tokens, is now a unit of economic value. Token budgets define what an engineer can accomplish, what a company can spend, and what business models work. Some companies are effectively inference providers wearing tool costumes. Neoclouds are the cleanest example. Cursor is another, subsidizing inference as a user acquisition strategy. The most absurd recent example: Allbirds, the shoe company, raised a convertible to build a GPU farm. Whether this becomes the AI version of Microstrategy’s Bitcoin trade or a cautionary tale, it tells you where the cost of capital believes the next decade is going.

    The Dot Com Survival Math

    Elad walks through the brutal arithmetic that AI founders should be internalizing. In the late 1990s and early 2000s, somewhere between 1,500 and 2,000 internet companies went public. Of those, roughly a dozen or two survived in any meaningful form. Every cycle has looked like this: automotive in the early 1900s, SaaS, mobile, crypto. There is no reason AI will be different. Most current AI companies, including those ramping revenue today, will see the market, competition, and adoption turn on them. The question every AI founder should be asking is whether they are in the durable handful or not.

    Most AI Companies Should Consider Exiting in the Next 12 to 18 Months

    This is the most actionable and most uncomfortable take in either source. While the tide is rising, every AI company looks unstoppable. Whether they actually are, in a 10 year frame, is a separate question. Founders running successful AI companies should take a cold honest look at whether the next 12 to 18 months is their value maximizing window. Companies typically have a 6 to 12 month peak before some headwind hits, often visible in the second derivative of growth. The best signal that you should sell is when growth rate is starting to plateau and you can see why. A handful of companies (OpenAI, Anthropic, the durable winners) should never exit. Many others should, while everything is still on the upswing.

    What Makes an AI Company Durable

    Elad lays out four lenses for evaluating durability at the application layer:

    1. Does your product get dramatically better when the underlying model gets better, in a way that keeps customers loyal?
    2. How deep and broad is the product? Are you building multiple integrated products embedded in actual workflows?
    3. Are you embedded in real change management at the customer? AI adoption is mostly a workflow change problem, not a tech problem. Workflow embedding is durable.
    4. Are you capturing and using proprietary data in a way that creates a system of record? Data moats are often overstated, but sometimes real.

    At the lab layer, Elad believes OpenAI, Anthropic, and Google are durable absent disaster. He predicted three years ago that the foundation model market would settle into an oligopoly aligned with cloud, and that prediction has roughly held.

    Selling Work, Not Software

    The deepest structural insight in the conversation is that generative AI is shifting what software companies sell. The old model was selling seats, tools, and SaaS subscriptions. The new model is selling units of cognitive labor. Zendesk sold seats to support reps. Decagon and Sierra sell agentic support output. Harvey can win in legal even though selling to law firms was historically considered terrible business, because Harvey is not selling tools, it is augmenting lawyer output. This shift opens markets that were previously closed and dramatically grows tech TAMs. It is also why founder limited theories of entrepreneurship currently understate how many opportunities exist.

    AI Eats Closed Loops First

    One of the cleanest mental models in the blog post is the closed loop framework. AI automates first what can be turned into a testable closed loop. Code is the canonical example: outputs can be tested, errors detected, models can iterate. AI research is similar. Both have tight feedback loops and high economic value, which puts them at the top of the AI impact ranking. Map jobs on a 2×2 of closed loop tightness vs economic value and you can see where AI hits soonest. The interesting forward question is which jobs become more closed loop next. Data collection and labeling will keep growing in every field as a result.

    The Harness Matters More Than People Think

    For coding tools and increasingly for enterprise applications, what Elad calls the harness, the wrapper of UX, prompting, workflow integration, and brand around the underlying model, is becoming sticky. It is not just which model you call. It is the environment built around it. Cursor and Windsurf demonstrate this in coding. The interesting open questions are what the harness looks like for sales AI, for AI architects, for analyst workflows. Those gaps leave room for startups even as model capabilities converge.

    Hidden Layoffs and the Developing World

    Most announced AI driven layoffs are probably just COVID era overhiring corrections wrapped in a more flattering narrative. But real AI driven labor displacement is happening, and it is hitting outsourcing firms first. That means countries like India and the Philippines, where many outsourced services jobs sit, are likely to be the most impacted earliest. Several developing economies built their growth ladders on services exports. If AI takes those jobs first, the migration and economic patterns of the next decade may shift in ways nobody is yet planning for.

    The Flat Company

    Multiple late stage CEOs told Elad they will not announce big AI layoffs. Instead, they will simply stop growing headcount. If revenue grows 30 to 100 percent, headcount stays flat or shrinks via attrition. Existing employees become dramatically more productive. The very best people who can leverage AI will see compensation inflate. Sales and some growth engineering keep hiring. Almost everything else flatlines. This is mostly a later stage and public company phenomenon. True early stage startups should still scale aggressively after product market fit, just with more leverage per person.

    Exit Options for AI Founders

    Elad lays out four exit categories. First, the labs and hyperscalers themselves: Apple, Amazon, Google, Microsoft, Meta. Second, vertical incumbents like Thomson Reuters for legal or healthcare giants for clinical AI. Third, the underrated category of merger of equals between two private AI competitors who are currently destroying each other on price. PayPal and X.com did this in the 1990s. Uber and Lyft reportedly almost did. Fourth, large adjacent tech companies: Oracle, Samsung, Tesla, SpaceX, Snowflake, Databricks, Stripe, Coinbase. The market cap math has changed in a way that makes acquisition trivial. One percent of a three trillion dollar market cap is 30 billion dollars, which means a hyperscaler can do massive acquisitions almost casually.

    Geographic Concentration Is Extreme

    Elad’s team analyzed where private market cap aggregates. Historically half of global tech private market cap sat in the US, with half of that in the Bay Area. With AI, 91 percent of global AI private market cap is in a single 10 by 10 mile square in the Bay Area. New York is a distant second and then it falls off a cliff. For defense tech, the cluster is Southern California (SpaceX, Anduril, El Segundo, Irvine). Fintech and crypto skew toward New York. The remote everywhere advice is, Elad says, just BS for anyone trying to break into an industry cluster.

    How Elad Got Into His Best Deals

    Stripe started with Elad cold emailing Patrick Collison after selling an API company to Twitter. A couple of walks later, Patrick texted that he was raising and Elad was in. Airbnb came from helping the founders raise their Series A and being asked at the end if he wanted to invest. Anduril came from noticing that Google had shut down Project Maven and asking if anyone was building defense tech, then meeting Trey Stephens at a Founders Fund lunch. Perplexity came from Aravind Srinivas cold messaging him on LinkedIn while still at OpenAI. Across all of these, the pattern is the same: be in the cluster, be helpful, be talking publicly about technology nobody else is talking about, and be useful to founders before any money is on the table.

    The One Belief Framework

    Investors love complicated 50 page memos. Elad believes the actual decision usually collapses into a single core belief. Coinbase: this is an index on crypto, and crypto will keep growing. Stripe: this is an index on e-commerce, and e-commerce will keep growing. Anduril: AI plus drones plus a cost plus model will be important for defense. If your thesis needs three things to be true, it is probably not going to work. If it needs nothing, you have no thesis.

    Boards as In-Laws

    Elad emphasizes that founders should treat board composition like one of the most important hiring decisions of the company. You cannot fire an investor board member. They have contractual rights. So if you are going to be stuck with someone for a decade, take a worse valuation for a better human. Reid Hoffman’s framing is that the best board member is a co-founder you could not have otherwise hired. Naval Ravikant’s framing is that valuation is temporary but control is forever. Elad recommends writing a job spec for every board seat.

    The Slop Age as a Golden Era

    One of the warmest takes in the blog post is the framing of the current moment as the Slop Age, and the suggestion that this might actually be the golden era of AI plus humanity. Before the last few years, AI was inaccessible and narrow. Eventually AI may become superhuman at most tasks. Today, AI produces useful slop at volume, which means humans are still needed to desloppify the slop, but the leverage on time and ambition is real. That makes the work fun. If AI displaces people or starts doing more interesting work, this golden moment fades. Elad also notes the obvious counter, that the era of human generated internet slop preceded the AI slop era. AGI may end the slop age, or alternately may be the thing that finally cleans up all the prior waves of human slop.

    Anti-AI Regulation and Violence Will Increase

    This is one of the more sobering threads in the blog post. Real world AI driven labor displacement has been small so far, but anti-AI sentiment is already strong and growing. Maine just banned new data centers. There has been actual violence directed at AI leaders, including a recent attack on Sam Altman. Elad’s view is that AI leaders should work harder on optimistic public framing, real political lobbying, and reining in the doom narrative coming from inside the field. Otherwise the regulatory and activist backlash will get much worse, and likely on the basis of mismeasured impacts.

    Right Now Consensus Is Correct

    The headline contrarian take from the episode is that contrarianism right now is wrong. There are moments in time when betting against the crowd pays. This is not one of them. The smart bet is just buying more AI exposure. Trying to find the clever angle, the underlooked hardware play, the secret macro thesis, is overthinking it. Save the contrarian moves for later in the cycle.

    Distribution Almost Always Matters

    Elad pushes back on the founder mythology that great products win on their own. Google paid hundreds of millions of dollars in the early 2000s to distribute its toolbar through every popular app installer on the internet. Facebook bought search ads against people’s own names in European markets to seed network liquidity. TikTok spent billions on user acquisition before its algorithm could lock people in. Snowflake spent enormous sums on enterprise sales and channel partnerships. Sometimes the best product wins. Often the company with the best distribution wins. Founders should plan for both.

    AI as a Cold Reader and a Research Partner

    Two of the more practical AI workflows Elad describes: First, uploading photos of founders to AI models with cold reading prompts that ask the model to identify micro features (crows feet from genuine smiling, brow patterns, posture cues) and infer personality traits, sense of humor, and likely social behavior. He reports the outputs are surprisingly specific. Second, running deep dives across multiple models in parallel (Claude, ChatGPT, Gemini), asking each for primary sources, summary tables, and cross checked data. He recently used this approach to investigate the rise in autism and ADHD diagnoses, concluding that diagnostic criteria shifts and school incentives drive most of it, and noting that maternal age has a stronger statistical association with autism than paternal age, despite paternal age getting all the public discourse.

    The First Ever 10 Year Plan

    For someone who has been compounding aggressively for two decades, Elad has somehow never written a 10 year plan until now. He knows it will not play out as written. The point is that the act of imagining a decade out shifts what you choose to do in the near term. He explicitly rejects the AGI in two years therefore plans are pointless framing as defeatist. There will be interesting things to do regardless of how the AGI timeline plays out.

    Thoughts

    This is one of the more useful AI investor conversations of 2026, mostly because Elad is willing to put numbers and timelines on things that are usually left vague. Pairing the podcast with the underlying Substack post is the right move because the post is where the GDP math, the closed loop framework, and the Slop Age framing actually live. The podcast is where Elad explains how he thinks rather than just what he thinks.

    The 12 to 18 month sell window framing is the most actionable single idea in either source, and probably the most uncomfortable for AI founders sitting on multi billion dollar paper valuations. The math is unforgiving. A dozen winners out of thousands. If you are honest with yourself about whether you are in the dozen, you know what to do.

    The Korean memory bottleneck framing explains a lot of current behavior. The talent wars make more sense once you accept that compute is not going to be the differentiator for two years, so people become the only remaining lever. The convergence of capabilities across OpenAI, Anthropic, Google, and xAI starts to look less like coincidence and more like the structural inevitability of a supply constrained input. The 2028 inflection date is the one to watch.

    Compute as currency is the cleanest reframing in the blog post. Once you start pricing companies in tokens rather than dollars, everything from Cursor’s economics to Allbirds raising a convert to build a GPU farm becomes legible. The interesting question is whether this is a permanent unit of denomination or a transitional one that fades when inference costs collapse.

    The software to labor argument is the structural framing that I think will hold up the longest. Once you internalize that we are not selling seats anymore but selling cognitive output, every vertical that was previously locked behind ugly procurement and IT inertia opens up. Harvey is the proof of concept. There will be 30 more Harveys across every white collar profession.

    The closed loop framework is the cleanest predictor of which jobs get hit hardest and soonest. If you want to know whether your role is exposed, the questions to ask are whether outputs can be machine evaluated, how tight the feedback loop is, and how high the economic value is. The intersection is where AI lands first.

    The geographic concentration data is genuinely shocking. 91 percent of global AI private market cap in a 10 by 10 mile area is the kind of statistic that should make everyone outside that square think very carefully about what game they are playing.

    The Slop Age framing is the most emotionally honest moment in the post. We are in a window where humans still meaningfully add value on top of AI output. That window is finite. Enjoy it.

    The anti-AI backlash thread is the one I think most people in the industry are still underweighting. Maine banning new data centers is a leading indicator, not a one off. The fact that the impacts are likely to be mismeasured by official statistics makes the political dynamics worse, not better. AI will get blamed for harms it did not cause and credited for none of the gains. If the field’s leaders do not start communicating better and lobbying smarter, the regulatory environment in 2028 will be much worse than in 2026.

    Finally, Elad’s first ever 10 year plan stands out as the most quietly important moment in the episode. The implicit message is that even people who have been compounding aggressively for two decades benefit from forcing a longer time horizon onto their thinking. Most plans fail. The act of planning still changes what you do today.

  • How AI is Revolutionizing Writing: Insights from Tyler Cowen and David Perell

    TLDW/TLDR

    Tyler Cowen, an economist and writer, shares practical ways AI transforms writing and research in a conversation with David Perell. He uses AI daily as a “secondary literature” tool to enhance reading and podcast prep, predicts fewer books due to AI’s rapid evolution, and emphasizes the enduring value of authentic, human-centric writing like memoirs and personal narratives.

    Detailed Summary of Video

    In a 68-minute YouTube conversation uploaded on March 5, 2025, economist Tyler Cowen joins writer David Perell to explore AI’s impact on writing and research. Cowen details his daily AI use—replacing stacks of books with large language models (LLMs) like o1 Pro, Claude, and DeepSeek for podcast prep and leisure reading, such as Shakespeare and Wuthering Heights. He highlights AI’s ability to provide context quickly, reducing hallucinations in top models by over tenfold in the past year (as of February 2025).

    The discussion shifts to writing: Cowen avoids AI for drafting to preserve his unique voice, though he uses it for legal background or critiquing drafts (e.g., spotting obnoxious tones). He predicts fewer books as AI outpaces long-form publishing cycles, favoring high-frequency formats like blogs or Substack. However, he believes “truly human” works—memoirs, biographies, and personal experience-based books—will persist, as readers crave authenticity over AI-generated content.

    Cowen also sees AI decentralizing into a “Republic of Science,” with models self-correcting and collaborating, though this remains speculative. For education, he integrates AI into his PhD classes, replacing textbooks with subscriptions to premium models. He warns academia lags in adapting, predicting AI will outstrip researchers in paper production within two years. Perell shares his use of AI for Bible study, praising its cross-referencing but noting experts still excel at pinpointing core insights.

    Practical tips emerge: use top-tier models (o1 Pro, Claude, DeepSeek), craft detailed prompts, and leverage AI for travel or data visualization. Cowen also plans an AI-written biography by “open-sourcing” his life via blog posts, showcasing AI’s potential to compile personal histories.

    How AI is Revolutionizing Writing: Insights from Tyler Cowen and David Perell

    Artificial Intelligence is no longer a distant sci-fi dream—it’s a tool reshaping how we write, research, and think. In a recent YouTube conversation, economist Tyler Cowen and writer David Perell unpack the practical implications of AI for writers, offering a roadmap for navigating this seismic shift. Recorded on March 5, 2025, their discussion blends hands-on advice with bold predictions, grounded in Cowen’s daily AI use and Perell’s curiosity about its creative potential.

    Cowen, a prolific author and podcaster, doesn’t just theorize about AI—he lives it. He’s swapped towering stacks of secondary literature for LLMs like o1 Pro, Claude, and DeepSeek. Preparing for a podcast on medieval kings Richard II and Henry V, he once ordered 20-30 books; now, he interrogates AI for context, cutting prep time and boosting quality. “It’s more fun,” he says, describing how he queries AI about Shakespearean puzzles or Wuthering Heights chapters, treating it as a conversational guide. Hallucinations? Not a dealbreaker—top models have slashed errors dramatically since 2024, and as an interviewer, he prioritizes context over perfect accuracy.

    For writing, Cowen draws a line: AI informs, but doesn’t draft. His voice—cryptic, layered, parable-like—remains his own. “I don’t want the AI messing with that,” he insists, rejecting its smoothing tendencies. Yet he’s not above using it tactically—checking legal backgrounds for columns or flagging obnoxious tones in drafts (a tip from Agnes Callard). Perell nods, noting AI’s knack for softening managerial critiques, though Cowen prefers his weirdness intact.

    The future of writing, Cowen predicts, is bifurcated. Books, with their slow cycles, face obsolescence—why write a four-year predictive tome when AI evolves monthly? He’s shifted to “ultra high-frequency” outputs like blogs and Substack, tackling AI’s rapid pace. Yet “truly human” writing—memoirs, biographies, personal narratives—will endure. Readers, he bets, want authenticity over AI’s polished slop. His next book, Mentors, leans into this, drawing on lived experience AI can’t replicate.

    Perell, an up-and-coming writer, feels the tension. AI’s prowess deflates his hard-earned skills, yet he’s excited to master it. He uses it to study the Bible, marveling at its cross-referencing, though it lacks the human knack for distilling core truths. Both agree: AI’s edge lies in specifics—detailed prompts yield gold, vague ones yield “mid” mush. Cowen’s tip? Imagine prompting an alien, not a human—literal, clear, context-rich.

    Educationally, Cowen’s ahead of the curve. His PhD students ditch textbooks for AI subscriptions, weaving it into papers to maximize quality. He laments academia’s inertia—AI could outpace researchers in two years, yet few adapt. Perell’s takeaway? Use the best models. “You’re hopeless without o1 Pro,” Cowen warns, highlighting the gap between free and cutting-edge tools.

    Beyond writing, AI’s horizon dazzles. Cowen envisions a decentralized “Republic of Science,” where models self-correct and collaborate, mirroring human progress. Large context windows (Gemini’s 2 million tokens, soon 10-20 million) will decode regulatory codes and historical archives, birthing jobs in data conversion. Inside companies, he suspects AI firms lead secretly, turbocharging their own models.

    Practically, Cowen’s stack—o1 Pro for queries, Claude for thoughtful prose, DeepSeek for wild creativity, Perplexity for citations—offers a playbook. He even plans an AI-crafted biography, “open-sourcing” his life via blog posts about childhood in Fall River or his dog, Spinosa. It’s low-cost immortality, a nod to AI’s archival power.

    For writers, the message is clear: adapt or fade. AI won’t just change writing—it’ll redefine what it means to create. Human quirks, stories, and secrets will shine amid the deluge of AI content. As Cowen puts it, “The truly human books will stand out all the more.” The revolution’s here—time to wield it.

  • How to Build the Future: Aravind Srinivas on Revolutionizing Search with Perplexity


    TL;DR
    In an insightful interview with Y Combinator’s David Lieb on February 21, 2025, Aravind Srinivas, co-founder and CEO of Perplexity, shares his journey from AI researcher to building a $9 billion-valued company in under three years. He discusses his motivations, the evolution of Perplexity, and his vision to redefine search by prioritizing user experience over traditional ad-driven models, positioning it as a potential challenger to Google.

    Executive Summary
    Aravind Srinivas’s story is one of curiosity, persistence, and bold ambition. From his early days as a PhD student at Berkeley and internships at OpenAI and Google, he identified search as a domain ripe for disruption through AI. Founding Perplexity, Srinivas aimed to create a user-centric, intelligent alternative to conventional search engines. The interview reveals how Perplexity evolved from early Twitter-based demos to a scalable, general-purpose search tool, leveraging advancements in large language models (LLMs). Srinivas emphasizes a relentless focus on user needs, team culture, and a long-term vision to integrate end-to-end solutions—beyond just answers—into everyday life.

    Key Takeaways

    From AI Roots to Entrepreneurial Ambition
    Question Answered: What inspired Aravind to start Perplexity?
    Metaphor: A gardener tending to a seedling, Srinivas nurtured his curiosity in AI research until it blossomed into a vision for a company that could grow as tall as the mightiest oaks (Google), fueled by the sunlight of innovation.

    Srinivas’s journey began in India, where his passion for deep learning led him to a PhD at Berkeley. An internship at OpenAI under Ilya Sutskever introduced him to unsupervised learning, planting the seed for a product-driven AI venture. At Google, reading In the Plex sparked his dream of building a company blending research and usability—enter Perplexity. His realization? Search and self-driving cars are rare domains where AI and product development create a flywheel, improving with every user interaction.

    The Birth and Evolution of Perplexity
    Question Answered: How did Perplexity find its potential?
    Metaphor: Like a sailor charting uncharted waters, Srinivas navigated through early demos (Twitter search) with a small crew, only to discover a trade wind—follow-up questions doubling engagement—that propelled Perplexity toward a new horizon.

    Perplexity’s early days were experimental. Srinivas and co-founder Dennis prototyped a Twitter search tool using OpenAI’s Codex, organizing data into tables for SQL queries. User engagement soared when follow-up questions doubled session times, signaling potential beyond niche applications. Pivoting to a general-purpose search engine, Perplexity embraced LLMs for unstructured data, betting on smarter models to outpace Google’s rigid indexing. This shift, sparked by a weekend prototype inspired by OpenAI’s Web GPT, marked its ascent.

    A User-Centric Approach to Search
    Question Answered: How does Perplexity differ from Google?
    Metaphor: Google is a bustling marketplace, hawking wares (ads) amid a sea of stalls (links), while Perplexity is a wise librarian, quietly fetching the exact book you need without pushing a sales pitch.

    Drawing from Larry Page’s mantra, “the user is never wrong,” Srinivas designed Perplexity to anticipate needs, not blame users for vague prompts. Unlike Google’s ad-cluttered results, Perplexity offers a clean, answer-focused experience—think healthy meal versus fast food. This philosophy drives its edge: obsession with user satisfaction and product finesse. Srinivas tracks queries per day, ensuring retention reflects genuine value, not forced interactions.

    Managing a Growing Team
    Question Answered: What’s the secret to managing a growing team?
    Metaphor: Srinivas conducts his orchestra with a steady baton, keeping the rhythm of queries per day in focus, ensuring every musician plays in harmony, not drowned out by the cacophony of bureaucracy.

    As Perplexity grows, Srinivas maintains a flat, data-driven culture. Weekly All Hands meetings spotlight queries per day, fostering transparency without constant scoreboard-watching. He engages directly with engineers on bugs, prioritizing product quality over hierarchy. Hiring focuses on passion for good work, mirroring his detail-obsessed DNA, though he acknowledges the challenge of scaling without slowing down.

    Competing with Google and Beyond
    Google’s ad-driven model and Microsoft’s consumer struggles leave room for Perplexity. Srinivas sees its advantage in agility and taste, unencumbered by legacy systems. While Google’s $200 billion search revenue looms large, Srinivas argues its stock-driven focus hinders bold pivots, giving Perplexity a shot at redefining monetization. He shrugs off early threats like Bing Chat, trusting in Perplexity’s user-first ethos to carve a niche.

    The Future of Search: Perplexity’s Vision
    Question Answered: What’s the future of search according to Srinivas?
    Metaphor: Imagine a trusty guide who not only points you to the mountain peak but hands you the gear to climb it—Perplexity aims to be that companion, merging answers with actions in a seamless journey.

    Srinivas envisions Perplexity as more than a search engine—an end-to-end solution. Whether recommending a sweater or booking a flight, it aims to deliver answers and actions. This requires orchestrating small models, knowledge graphs, and widgets—a daunting task, but one Srinivas believes can rival Google with a decade of perseverance. Unlike subscription-only models, he seeks sustainable monetization, balancing user trust with mass-market utility.

    Why Perplexity Could Win
    Unlike AI-centric firms like OpenAI, Perplexity blends model expertise with user obsession. Its DNA prioritizes product over benchmarks, positioning it to solve real-world problems—shopping, travel, quick facts—without drowning in ad revenue pressures. Srinivas bets on taste and persistence, not just tech, to outmaneuver competitors over the next decade.
