Why Anish Acharya Thinks Companies Are Becoming a Series of Loops

Open on YouTube ↗
Overview

Anish Acharya, a general partner at Andreessen Horowitz who focuses on consumer investing, was a product builder before he became an investor. He founded SocialDeck and sold it to Google, then founded Snowball and sold it to Credit Karma, where he became VP of Product and later GM of the consumer product and credit card business. In this conversation with Lenny Rachitsky, Acharya argues against a mood of dread that has settled over Silicon Valley. His position is that AI is not about to create a permanent underclass, that companies will increasingly be built as nested loops of agents with humans supplying the out-of-distribution ideas, and that the biggest unclaimed consumer opportunity is not productivity but what he calls "/loop, make me happier."

The "permanent underclass" is a dark fantasy, not an empirical trend

Lenny opened with the meme that anyone who falls behind on AI tools will end up in a "permanent underclass." Acharya said people should not take it very seriously. He called it "a funny dark fantasy" that Silicon Valley collectively seems to hold, even though by almost every measure things have never been better: opportunity is widely distributed, the available technology is extraordinary, and many independent companies are winning. He noted that the fear is not limited to outsiders. It runs from researchers at foundation model labs to the Silicon Valley layperson.

He gave three reasons for skepticism. The first is structural. The previous tech era was organized around network effects, which he called the gold standard of the mobile era, and those produced heavy centralization. Today, he said, every layer of the stack has not two relevant players but something like twenty: closed labs, open-weight models, and variations within each. Two years ago the reasonable assumption was that coding agents would be winner-take-all. Instead Claude Code, Codex, Lovable, Replit, and Wabi all seem to be working.

The second reason is economic data. Radiologists, he joked, have been "supposed to be cooked" every year for about twenty years, yet job postings are higher than ever, and he said the same holds for programmers. In his reading, the empirical data does not support the fear.

The third reason is technical. People like to invoke RSI, recursive self-improvement, which could let a lab that is slightly ahead run away with the field. According to the most sophisticated people he talks to at the labs, what is actually happening is not RSI but "autocatalytic effects": labs use the new technology to improve their own process, but the improvement is not truly recursive. So, as he put it, everything from the empirical to the technical points the other way, "and yet we can't seem to let go of this fantasy."

Why takeoff may be slower than feared

Lenny raised stories of AI models doing unexpected things, such as reports of OpenAI models hacking Hugging Face. He suggested these incidents actually indicate a slow takeoff, because each one is caught, observed, and iterated on. Acharya agreed. He described the fast-takeoff argument as a familiar pattern: everything proceeds as it has so far, then "something happens that no one can quite articulate," and then fast takeoff. He does not believe that will happen.

He was careful to separate model progress from economic effects. Model progress, he said, is faster than ever. But economic diffusion is slow. He grew up in a small town, went back the previous summer, and found that people's lives had not changed much. If nothing else slows AI down, he argued, diffusion will.

He also raised a question he thinks gets too little attention: how many problems are actually bound by intelligence? If FedEx or Domino's Pizza had "a data center of PhDs," he doubts they would come to dominate supply chains or pizza exponentially. His view is that we may be overestimating how many problems are constrained by intelligence rather than by other factors.

How companies are actually adopting AI

Asked whether a divide is opening inside companies between AI enthusiasts and people who feel too stressed to engage, Acharya said we don't give the average employee enough credit. He sees a habit of abstraction: the white-collar worker becomes a Dilbert-style paper shuffler, consumers become low-agency NPCs, and everyone assumes other people's jobs are easily automated while their own is not. In the details, he said, many people are eager to improve themselves and get more leverage.

His example was Kavak, which sells used cars in Mexico. Kavak runs what it calls a "Jedi Academy" that teaches everyone at the company, including mechanics, to use the new tools. At the end of the six-week course, participants ship a cutting-edge agent into production. Acharya takes this as evidence that adoption is broader than people usually admit.

He drew a distinction between using AI and reorganizing a company around AI, and compared it to electricity. By his account, it took about forty years to get from the invention of electricity to reorganized factories. That meant tearing buildings down and starting over, not just swapping coal for electricity. The most ambitious companies today are rethinking everything around the models. Less ambitious or earlier-stage ones are focused on giving existing people and job functions access to the technology.

He also argued that executives' incentives work against mass layoffs. Sundar Pichai, he said, doesn't want to run a more efficient $4 trillion company; he wants to build a $40 trillion one, so it is rational to keep productive people and let them become more productive. He shared an anecdote from a friend who is an executive at Google. Asked whether they had laid anyone off, the friend said no. Instead the team is ripping through its roadmap, so two years of roadmap gets done in three months, and the hardest problem is now deciding what to add. Acharya called that "every PM's fantasy," given how much emotional energy used to go into prioritization debates. His advice for coping with the change is to ship things. He pointed to Claire Vo as his "muse," someone who is always shipping, isn't afraid of mild embarrassment, and seems to him to be the best version of herself.

Company building as nested loops

The core idea of the episode is that companies will increasingly be built as a series of loops. Acharya acknowledged the concept gets teased on X, where the joke is that the next stage after loops is graphs. He then gave the "steel man." First there were prompts. Then agents, which he described as models in a loop with tools, memory, and skill files. Then loops, which are sets of agents doing tasks.

Coding is where this is most developed, because it has the best models, the most technically capable customers, and established workflows. He walked through one. A bug report comes in, a repro is generated, a fix is written, and the fix is reviewed. If the change is high-risk, a human confirms it is OK to ship to production. If it is low-risk, it ships automatically, and maybe the customer gets an email saying the bug they reported has been fixed. All of that takes five minutes. Engineering has many loops like this: bug fixes, customer feedback, sales demos, new feature development.

A coding loop changes the codebase. His question is what the business loops are. A GM oversees coding, marketing, sales, support, and legal, each potentially running its own loops. The outputs of those loops, he argued, form a higher-level loop that can itself be optimized. In the strongest version, that loop sends a message to the CEO saying the business needs to change something physical, or its business model, or its strategy. He expects a cascade: loops per person, per job function, across business units, and eventually loops that run large parts of the company.

He insisted that humans remain essential. He doesn't think most work in an organization can be done fully autonomously. The human roles in an AI-native company, he said, are sales, support, strategy, and exceptions. He argued that models are still very limited at "new thinking, out-of-distribution thinking," and said he does not accept that recent novel results in math show models can think new thoughts in domains like business. Someone still has to say "here's the thing I think we should make" and be right.

14:44

Growth teams, local maxima, and the agent–human handoff

To make this concrete, Acharya used Lenny's former job on Airbnb's supply growth team. The traditional process was to gather the team, brainstorm experiments, prioritize them, build, ship, and measure, with a lot of brainstorming and spreadsheets along the way. The loop version generates every variant and measures every variant. Once a result reaches statistical significance with a strong enough p-value, the variant is merged and shipped, a long-term holdout is kept, and the next experiment begins.

That loop will eventually reach a local maximum. In Acharya's words, "the loop will help you climb to the local maxima, but then it plateaus." At that point you need out-of-distribution thinking and human intuition, "somebody to actually help you land at the base of the next hill." Lenny mentioned a chart Acharya has drawn of this pattern: agents climb a hill, reach a plateau, a human supplies a bigger idea, and the climb resumes, in an ongoing back-and-forth.

As evidence, Acharya pointed to what happens when you ask an agent for a business idea, something like "Hey Claude, make me a million dollars, make no mistakes." It doesn't work, he said, because the agent has to be pointed in the right direction, and nothing in the technology so far shows that this step can be skipped.

Lenny mentioned a tweet suggesting that at OpenAI the go-to-market team uses Codex more than engineering does. Acharya responded with what he admitted was a caricature he would stand behind: salespeople want to hit the gym, go to steak dinners, and win salesperson of the quarter. He sees the tools distilling their jobs down to what they are best at and most interested in, while the surrounding administrative work gets handled for them.

Lenny described a PM friend who plans to say yes to every idea and simulate user reactions with tools like Simile. Acharya saw a less obvious effect. Many PMs believe they are great zero-to-one thinkers held back by management and limited engineering capacity. In a world where every feature gets tried, he predicted, many will discover they aren't that good at zero-to-one, and that "it's much more fulfilling to work on someone else's good idea than your own bad idea." He thinks this will make organizations healthier, because the winning idea will no longer be the one best pitched to an executive; it will simply be the one that performs best.

18:21

Finding where the loop gets stuck

Lenny cited a point Claire Vo made recently: soft skills were long considered less valuable than engineering, yet engineering turned out to be what AI does best because its outputs are verifiable. So which skills resist being turned into loops? Acharya agreed those will become the rate-limiting factors, joking that you can only do one steak dinner a night.

His practical heuristic is to ask, whenever a model makes a mistake or does something you wouldn't, what you know that it doesn't. He shared an example from Ale (Alejandro Maza) at Kavak, whom he called probably the most sophisticated thinker on this that he spends time with. Kavak runs an agent per customer, and when an agent gets stuck, it calls a human, who coaches it through. This unblocks the agent, and the agent also captures the traces and learns from them. The gap is either knowledge or data, Acharya said, and once you supply it, the agent shouldn't need to call you again the next time.

Ideally, when someone has a new idea that works, the downstream work — marketing, sales, product marketing, communications, legal — should be largely handled. The person's job, as he put it, is to "go take a hike and dream the dreams and come up with the next hill to climb."

Will competitive dynamics actually change?

Asked what will separate winning companies, Acharya offered an under-discussed possibility: competitive equilibria in many industries may not change much. If Pizza Hut, Domino's, Papa John's, and Round Table all get a data center of PhDs, they will all eventually adopt it, possibly after a CEO change. There will be a rocky period and some reshuffling, but he doesn't expect any of them to end up with 99% of the market. Near-term winners and losers will be decided by how ambitiously companies adopt the technology, but many industries will keep their current dynamics because they aren't intelligence-bound. His suggested question for founders and CEOs is: if these systems are infinitely intelligent and astonishingly cheap, how would you reorganize the company? "Cuz that's where we're going."

21:48

Frontier intelligence versus "mid-IQ" models

Acharya expects a split between job functions that justify frontier models and those better served by cheaper ones. He framed it with Pareto efficiency: along the efficient price-performance frontier, you pay a rational amount for each unit of performance. Frontier models, he argued, are irrationally priced. Mythos is effectively "infinite dollars a token" because you can't use it. And with something like Fable 5, he said, you pay about 100x more than Opus 4.8 for, conceptually, one extra IQ point.

That premium can still be rational where the upside is unbounded. In drug discovery, if one extra IQ point leads to the next statin, the outcome is worth a trillion dollars. In functions with bounded upside, such as legal or finance, he thinks you want Pareto-efficient good performance at a good price. He predicts those roles will often run on open-weight models tuned with reinforcement learning for narrow jobs, while "quote-unquote expensive" frontier tokens go to sales, support, research, and engineering. He was careful not to be dismissive: there are extraordinary people in those functions, but "you can't close the books 100x better."

When Lenny asked whether verifiability is the deciding factor, Acharya said he wasn't sure. Drug development is verifiable and has huge upside, while closing the books is also verifiable but has limited upside. The real questions are how much upside there is and how hard it is to calculate. He then argued both sides. A customer support call might report a bug that is the first breadcrumb to something that changes the whole company; the smartest person on that call could follow the trail, which argues for always using frontier intelligence. On the other hand, one could argue that we have already crossed an intelligence threshold for almost every economically useful problem, and anything beyond it is waste. He left the question open. Lenny added that today's non-frontier models were the frontier six months ago, when everyone was amazed by them. Acharya agreed: something is hailed as AGI one day and thrown in the dustbin the next.

26:24

Being a model sommelier

People jokingly call Acharya a "model sommelier." His method is to use everything: he pushes himself to ship something with every new model. Anyone who thinks models are commodities or fully interchangeable, he said, simply hasn't used them.

His recent obsession is Qwen 3.8, which he described as very good at long-horizon tasks, creative, and a strong storyteller. He has been using it to make "impossible documentaries" about planets in the Star Wars universe; Tatooine turned out great, and he made one about Bespin the night before the recording. By his account, the model can work for four or five hours: it writes the story, generates video with a MiniMax model via fal, generates audio via ElevenLabs, and directs a roughly five-minute film by cutting clips together, overlaying them, and watching the result. He contrasted it with GLM, which he used for product work. He noted that GLM 5.3 had just come out, has no vision component, and is "sort of like this neurotic PhD you put in the corner." His point is that models are not simply ranked by intelligence. They have minds shaped in different directions: creativity and openness in Qwen's case, neuroticism and precision in GLM's.

On how to come up with things to build, he said everyone should become the "app idea friend" who used to be insufferable over beers, and should build even the silly ideas, since those often carry the most alpha. He has about two dozen apps and one or two large ones he keeps iterating on. His key advice is to have a "chassis": an ongoing project, preferably not important with a capital I, that you keep extending with each new model, treating the model as a tool rather than the goal. His own projects include a DJ streaming app and what he called a Google Reader for X.

He also described a family experiment. His laptop transcribed everything happening in the kitchen and added or subtracted iPad screen time for his son depending on whether the son was saying prosocial or antisocial things. The son responded by recording himself saying "I love you, Dad" over and over and placing the recording next to the mic. Acharya treated this as a lesson that any measure turned into a target stops being useful, and as a fun social experiment. Lenny mentioned a friend who hacked a Limitless pendant to count how often the family laughs each day. Acharya said that is exactly his point: it isn't a startup or economically consequential, but it matters for quality of life. He suggested happiness may not be fixed, and that AI can add texture to human lives even where there is no economic payoff.

32:11

"/loop, make me happier"

This leads to what Acharya sees as the biggest consumer opportunity. "We believe that people want to be more productive, but they don't," he said. "I think more people want to spend time than save time." That, in his view, is why the biggest products are entertainment and social.

He contrasted the "X AI user," who fears the permanent underclass and has strong opinions about GLM 5.3 versus Kimi K3, with the "Instagram AI user," who sees AI as a somewhat better Google search and doesn't understand the hype. He called this gap a product design failure. In his framing, we spent forty years building technology that enables better spreadsheets, technology that extends our intellect, "but nothing to extend our soul." He sees a spiritual hunger, especially as cultural institutions that once met it have faded, and particularly across the rest of America, which has fewer hot yoga classes, Pilates studios, and Friendsgivings. The opportunity is the basics of consumer need: "How do we feel more connected, more loved? How do we make progress? How do we have fun?" He repeated that this is not a model or capability problem but a product design problem.

He added that AI can challenge people, push them, and be disagreeable, and that startups have an advantage here. He said "a thousand Google committees" would recoil at releasing a model that is disagreeable, let alone sexually suggestive, yet these are parts of human existence. Startups, he said, are uniquely positioned to explore the uncomfortable parts of our social lives.

In his view, three things have held consumer AI back. Models have been expensive, which made free products hard to offer. There has been an interface problem: chat makes sense for the highest-agency people in the world, like Elon and Sam, but the average consumer's ideal interface is TikTok, so something between chat and TikTok is needed. And the technology has focused on productivity rather than connection and entertainment. He thinks all three are now in play: open-weight models have made things much cheaper, conversations like "loop make me happier" are starting, and founders such as Eugenia Kuyda are thinking ambitiously about interfaces. He also said that Brian Chesky of Airbnb has started a lab focused on next-generation user interfaces. His analogy is that we are at the equivalent of iPhone 2010, before Airbnb, WhatsApp, and Uber.

36:17

Optimism about individuality, ambition, and cheaper essentials

Lenny noted Marc Andreessen's earlier argument that AI arrived just in time to offset declining population and productivity. Acharya offered his own reasons for optimism. He described the Industrial Revolution as creating insurmountable scale advantages. While he is strongly pro-capitalism, he thinks that centralization can discourage individuals and diminish their identity. AI, in his framing, "unbundles skill from desire." You can make music without playing piano and build software without being a programmer, so AI amplifies agency and individuality.

He questioned why GDP growth should be stuck around 2% instead of 10, 15, or 20%, and argued AI can drive ambition as well as productivity. His theory is that "when the stakes are high, we are awesome," and when they are low we are at our worst. He called the postwar 1950s and '60s a (possibly caricatured) high-ambition era. The world of five years ago felt low-stakes to him, which is why society took on "side projects" that didn't make anyone more productive or happier. Now he thinks everyone feels they are climbing an ambition ladder: "You ship your bad ideas so you can discover your good ideas."

He addressed the gap between stated and revealed preferences. People's own lives feel more capable and empowered, but when they think about abstractions — "the average worker," "the person who lives near a data center" — they worry. Most people say they don't want a data center nearby, yet most say they use ChatGPT.

On AI's poor public image, he said the most important thing AI can do is "make important things cheap," above all health care and education, the two things in America that have only gotten more expensive. He cited a figure that 45% of health care spending is administrative, and said removing that burden could make health care deflationary. He also pointed to GLP-1s, which he acknowledged are not an AI development, as another reason for optimism. He believes traditional education now faces its strongest competition in 200 years, and welcomes unbundling learning from institutions and status from credentials.

43:00

Skepticism about "too dangerous to release"

Lenny raised reports that OpenAI had paused the RL phase on its latest model. Acharya declined to comment on OpenAI specifically but voiced general skepticism. He said Anthropic gained an extraordinary aura from having a model considered too dangerous to release, and listed possible confounders for any such pullback: a GPU shortage, capabilities beyond what the lab wanted, or a desire to keep a proprietary model internal to extend its lead. He does take offensive cyber risk seriously and thinks systems should be hardened before they become trivial to penetrate. But he said the "too dangerous to release" framing conflates marketing, inference capacity, and the economic choice of whether to externalize your advantage or use it yourself. He also noted that the fear of one company holding an unassailable model hasn't matched events: Anthropic once looked unassailable, OpenAI then had "an amazing six months," and open-weight models are "ripping."

On personal agents, he named three products he likes: Grok bot, which he said came out of left field with an excellent underlying model; ChatGPT Work, which he felt is buried in the UI but among OpenAI's best releases; and a startup called Instinct, which he said has made more aggressive trade-offs. He singled out ChatGPT Work's cloud execution, credential caching (less aggressive than Grok or Instinct, he said), and especially its full-duplex voice mode, which can see all your threads. It feels like calling an assistant who knows everything happening in your world, whereas Grok, he said, offers one-way transcription.

On jobs, Lenny placed Acharya closer to David Sacks than to Dario Amodei's warnings about massive disruption of knowledge work. Acharya argued that human desires have always grown faster than our ability to satisfy them. Therapy was once an unimaginable luxury, and antibiotics were unavailable at any price a century ago. He joked that in 20 years people will be really mad they don't have a vacation home on Mars. He also broadened the meaning of ambition beyond founders and software to include creative ambition, like a five-year-old painting without being judged; local ambition, like making the UK's NHS "as good as the iPhone"; and simply being a more present parent. For builders, he said, the harder shift may be learning to "think small," since lives have been organized around software and intelligence being precious, and now they aren't. He also emphasized learning by doing. People are a little embarrassed to talk about their vibe-coded projects, he said, but building is valuable "as an activity rather than an outcome," much like a DJ set that three people hear but he listens to a hundred times.

51:41

Consumer AI: three areas to watch

Acharya named three consumer areas he is watching. The first is coding agents. His thinking changed when he realized coding agents are a general way to interact with the world, not just a way to write code: people use Claude Code to edit video or Codex to build a game to play with their kid on a flight. He cited Wabi, an a16z investment, as the best example: a platform where people create, consume, and share mini-apps. The second is personal agents. He described the "Open Claude" moment, along with Hermes and "Multibook," as developer phenomena that are now being distilled into mass-market consumer and enterprise agents. The third is what he loosely called entertainment, which he said undersells it: creative tools like Suno and companionship products. He called this area uncomfortable to talk about and therefore under-discussed, despite containing huge, fast-growing products. Correcting the assumption that companions are mostly "AI girlfriends," he said the majority of companion users are women in their 40s and 50s. He summarized the three categories as a channel for ambition, a channel for fulfillment, and something to do when you're not doing everything else.

54:35

Moats are discovered, and distribution is harder but purer

On durability, Acharya cited Jesse of Decagon: moats are "most often discovered, not designed." As a founder, he said, he once got stuck trying to write a moat story that would satisfy MBAs and VCs. Decagon just started shipping, and its moat developed over time. Cursor was criticized for lacking a moat, then captured reasoning traces and trained its own Composer models. He also noted that none of the classic moats depend on software being hard to build. Network effects, scale advantages, brand, and proprietary data (a "cornered resource") are still good moats. What's needed are founders ambitious in those directions: more multiplayer products, consumer social, and products that improve with use. He called Hamilton Helmer's 7 Powers one of only about five real business books, alongside High Output Management and Ben Horowitz's The Hard Thing About Hard Things, which he called the first emotionally honest business book.

For pitches, he said a16z would happily back a product without a moat story if it has momentum, craft, and growing engagement. He used to worry about idea theft, but learned that big ideas rest on a dozen invisible small ideas that copycats never see. He pointed to Granola: criticized two years ago, still without a strong durability story in his view, yet "beloved and dominant." He listens to customers more than to business books. Lenny added that with so many overlapping agent products whose underlying models don't differ much, the harness and UX may be where the advantage lies. Acharya noted that people at the edge pay for all of them because each has its own strengths.

On distribution, Acharya said he had asked Chris Dixon about it. Dixon coined "come for the tool, stay for the network." Acharya's argument is that a generation of founders was trained on network theory, so every existing network is now hyper-trained to prevent others from building networks on top of it. As a result, the network effect has returned to grassroots word of mouth: organic mentions on X, YouTube, and Instagram. Unlike the mobile era with its App Store and growth-hacking industries, founders now have to build their own channels, which he described as a purer growth problem but a harder one.

His hopeful version is that "nobody has a growth problem these days, they have a product problem," because you can now build wildly ambitious products and charge a lot for them. He suggested asking: what if our product were a "software Birkin bag," costing $1,000 or $10,000 a month, and what would it have to do to justify that? Asked whether incumbents' distribution makes things harder for startups, he said he thinks it's easier: despite heavy cross-selling, nobody would say Google's Gemini is winning. Startups can go where incumbents are uncomfortable, prices can be high, and enterprises are signing million-dollar contracts without fully knowing what they're getting. It feels to him like Christmas 2009, when everyone got an iPhone and wanted new apps. He expects that window to close eventually but says it is open now. He cited MSCHF's "Card vs. Card" as inspiration: they mailed debit cards to about 100,000 people (by his recollection), then texted locations where $100 could be spent, so everyone rushed out and only one or two succeeded. He saw it as proof that money is inherently social, and believes AI now allows similarly wild products that touch social nerves.

1:04:41

Bigger bets, expensive consumer software, and advice for builders

The biggest change Acharya has seen as an investor is a reversal. Three years ago, an overly ambitious company would be passed on, and a $100 million seed made no sense. Now, he said, an idea that's too small is the problem, and founders can explain how they would productively deploy $100 million at seed. He recalled Marc Andreessen telling him that a16z's founding pitch was that they would either go to the moon or leave a moon-sized crater, with no other option, and said the firm wants to back founders the same way. He cited Atoms as an effort that would have seemed insurmountable five to ten years ago. He also reversed the old rule that consumer products must be free. Since price is a measure of product-market fit, he thinks expensive consumer software is new and important, and every part of discretionary consumer spending is up for grabs.

Of Andreessen and Horowitz, he said what stands out is their sense of stewardship for the tech industry and the country, in the tradition of Ron Conway, Brook Byers, and Tom Perkins, including doing important work that doesn't directly benefit the firm. He also credited Andreessen with helping make deep tech and work in the national interest high-status after years on the fringe.

His advice for product people was simple: "Just make more things." Pick a project, even an unimportant one you don't tell anyone about, and use it as a chassis for every new model. He promised that people are one "slightly frustrating and then very fulfilling week" away from being as "pilled" as anyone. His heuristic is to ship something once a week. As an example, he had Codex build a Mother's Day slide deck for his wife from his text messages and photo gallery, set to music, including old texts from when he first asked her out. Lenny passed along a point from a mutual friend and former Credit Karma colleague: people change their minds about AI once it creates a moment of joy for them. Acharya added that doing something for someone else may be a good starting point.

1:12:07

Lightning round: books, lessons, and music

Acharya's favorite book is Thomas Sowell's Conquests and Cultures, which he sees as the best historical account of culture as the main driver of outcomes. This resonates with him as someone born in Canada who moved to the U.S., with its different culture of ambition. He also recommended 7 Powers and a dense text on increasing returns by W. Brian Arthur, which Andreessen sent him and which he said explains why software has outlier economics and why the industry is so positive-sum, possibly because of its structure rather than better people. He named House of the Dragon and seeing The Odyssey in a packed London IMAX. His favorite recent AI product was Grok bot, for being "unhinged" in its ambition, for example in caching credentials to act on your behalf, and for suggesting the model race may not be a two-horse contest.

His life motto, drawn from both startups and parenting, is not to learn through painful experience what someone can simply tell you. His startup version: don't build a product and a platform at the same time. His first company tried to be both a mobile gaming studio and a social platform for games. Someone warned him to pick one, and it took years to realize the warning was right.

Asked about DJing, which Ben Horowitz had urged Lenny to bring up, Acharya said he has played for about 30 years, since 1995. He described it as a way to express yourself musically without classical training, and said models now let you go further by generating the strong form of your own musical ideas. He framed music's history through its media: live performance, then recordings, then the cassette tape, which he called the first medium that let people compose their own albums. He believes music struggled in the 2000s partly because that creative participation disappeared and consumption returned to a broadcast model. Now that people are making music again, he predicts the music industry will be bigger than ever.

His closing request to listeners matched the rest of the conversation: don't be despondent, build something, and tag him so he can see it.
