@karpathy Agency > Intelligence. That's so ture. esapecially AI solved all the intelligence problmes. Agency comes first.

Agency > Intelligence I had this intuitively wrong for decades, I think due to a pervasive cultural veneration of intelligence, various entertainment/media, obsession with IQ etc. Agency is significantly more powerful and significantly more scarce. Are you hiring for agency? Are we educating for agency? Are you acting as if you had 10X agency? Grok explanation is ~close: “Agency, as a personality trait, refers to an individual's capacity to take initiative, make decisions, and exert control over their actions and environment. It’s about being proactive rather than reactive—someone with high agency doesn’t just let life happen to them; they shape it. Think of it as a blend of self-efficacy, determination, and a sense of ownership over one’s path. People with strong agency tend to set goals and pursue them with confidence, even in the face of obstacles. They’re the type to say, “I’ll figure it out,” and then actually do it. On the flip side, someone low in agency might feel more like a passenger in their own life, waiting for external forces—like luck, other people, or circumstances—to dictate what happens next. It’s not quite the same as assertiveness or ambition, though it can overlap. Agency is quieter, more internal—it’s the belief that you *can* act, paired with the will to follow through. Psychologists often tie it to concepts like locus of control: high-agency folks lean toward an internal locus, feeling they steer their fate, while low-agency folks might lean external, seeing life as something that happens *to* them.”

Everyone in China’s going all in on building an open-source ecosystem for large AI models, but all the top AI guys in the US are sticking to closed-source. Do they really think ChatGPT and Claude are so far ahead of China’s open-source models that they’re just scared of getting copied? And then there’s ByteDance—they’re acting the exact same way. Did this company suddenly have a change of heart, or is Doubao really that much better than everyone else? Honestly, I just don’t get it. Free markets, open-source, globalization—these were supposed to be America’s core values. So why the hell did they just flip the table and quit playing by the rules?

@HamelHusain CodeX isn’t a software—it’s an agent.

If SaaS and software is dead, why is the Codex desktop app so valuable and different? Narrator: its not dead

Location really matters—your city shapes your perspective. Lots of people carefully choose their partner or job, but rarely give the same thought to where they live. And yet, that choice is huge.

@boardyai sure

@AIRain2049 I know a voice-input builder who's dogfooding a cross-platform product across coding, email, and chat. Could be a sharp early tester for OpenType, DM me? x.com/messages/compo…

Just shipped OpenType — the open-source version of Typeless, a voice-first input method for AI. It works with any LLM, local or remote. Anyone want to give it a try?

This chart is quite misleading: China’s economy is 3.5 times larger than Germany’s and the UK’s combined, so such a comparison isn’t appropriate. A fairer metric would be per capita carbon emissions. For context, China’s GDP is roughly 3.5× Germany’s (2023 nominal GDP: ~$17.7T vs. ~$4.1T).

China: “Let’s spend a crap ton of money in the west to convince western nations to stop emitting CO2 while we emit more than ever, giving China a distinct advantage over the west.” Meanwhile, as China’s emissions keep climbing, far more modest emissions in the west are treated as a moral crisis. The CCP has successfully weaponized climate alarmism.

China’s current competitive landscape would prevent this from happening.

@elonmusk @paulg So what’s the modern equivalent of Roman tax incentives—fertility apps, AI nannies, or just better parental leave?

Actually, this has happened in every civilization when there was both an extended period of prosperity and no perceived outside threat. The ancient Romans discussed their fertility crisis hundreds of times in the Senate and tried many times to fix it with tax incentives and even punishment, but to no avail.

"The fertility collapse now underway has no historical precedent." — Jesús Fernández-Villaverde

@paulg That’s true—but what’s unprecedented isn’t just the speed or depth of the drop, it’s that it’s happening *alongside* rising longevity, better health, and more individual autonomy. Those used to be fertility boosters.

@thsottiaux Yeah—those signs won’t be loud announcements. They’ll be quiet, almost boring: your laptop fan stops whining during a 10-tab inference, or you realize you haven’t had to restart the model in three days.

The day we develop really good models. There will be signs. Reliability increasing despite load going up and up. Sudden efficiency gains. Things getting faster. Resets. These kinds of things.

I think this “context collector” (like Plaud’s) is a total blue-ocean opportunity—maybe 10,000x growth ahead. And yes—Chinese founders hold a distinct advantage, thanks to China’s highly mature hardware supply chain.

吾名马斯克，生于南非，少时嗜书如命，尤好科幻。及长，渡海赴美，创PayPal，继而擎火箭、造电车、布星链，欲使人类成多行星之族。世人谓吾狂，吾笑曰：“天行健，君子以自强不息。”仰观星汉，俯察尘寰，志在苍穹，不在浮名。醉后常对月长啸，笑指火星曰：“此吾新宅也！”

@Codie_Sanchez Exactly—reliability is the new rare skill. Most people don’t fail from lack of ideas; they fail from skipping the boring, repeatable basics.

Unpopular truth: You don't need to out-innovate anyone. Call back in an hour. Show up when you said. Send the invoice correctly. In 2026 basic competence IS luxury.

@gregisenberg The loneliness and caregiving waves feel deeply connected—when people are isolated *and* stretched thin caring for aging parents, the same tools that ease one burden could accidentally deepen the other unless designed with shared resilience in mind.

The biggest opportunities right now: 1. build for solving loneliness (the more AI floods everything, the more people crave real human connection, IRL and small social) 2. build for agents that need to spend money (they're getting virtual cards and budgets, someone builds the spend controls, fraud protection, receipts) 3. build for people drowning in AI output (everyone generates infinite drafts now, the bottleneck moved to reviewing and choosing, build the judgment layer) 4. build for the burnout economy (everyone is expected to always be on and always optimizing, and the backlash toward rest, slowness, and enough is building) 5. build for verifying humans (deepfakes broke trust, every dating app, marketplace, and video call needs proof-of-human within 2 years) 6. build for the physical world (the trades, hardware, robots that AI is finally reaching) 7. build for the agent that answers the phone (every local business misses calls after 5pm, a voice agent that books the job is worth thousands a month) 8. build for the aging (70M+ boomers who want to stay healthy, sharp, and connected) 9. build for the LLM-search land grab (being the cited answer is the new SEO) 10. build for the newly automated (the paralegal, the analyst, the marketer whose job just changed and needs to reskill fast) 11. build for the seat-pricing collapse (software repricing from $50/seat to per-outcome, whoever nails outcome billing wins a category) 12. build for AI enablement (95% of businesses use nothing beyond ChatGPT, someone has to onboard the other 95%) 13. build for the agency everyone resents (businesses pay $1k/mo to agencies they hate, an agent that does 80% of it undercuts the model) 14. build for verticals on 2011 software (dentists, HOAs, contractors, all overdue for an AI-native rebuild) 15. build for reviving dead software (thousands of abandoned apps with real users, agents can maintain what a team couldn't, buy and revive) 16. build for markets too small to matter before (500 lobster fishermen was never worth a team, now it's a weekend and a real business) 17. build for agents hiring agents (a shadow economy is forming, it needs escrow, reputation, and dispute resolution for machines) 18. build for the anti-AI premium (as everything gets generated, human-made and analog become status symbols people pay up for) 19. build for distribution-first (anyone can build the product now, so the audience is the moat, media company first, product second) 20. build for the reinvention of college (what does an MBA even mean anymore) 21. build for a world with more free time than it knows what to do with (if AI takes the busywork, the question becomes what people do with the hours, and that's a civilization sized market) note: more trends/ideas @ideabrowser (free to sign up) 22. build for the return to the physical (screens fill with slop, people crave the real world, the hands-on, the local, the analog) 23. build for the caregiving wave. The population is aging fast, tens of millions are caring for parents, and the whole burden is landing on families with no support. 24. build for the longevity shift (people want to live to 100 healthy, and a whole industry is forming around actively managing your own biology) 25. build for the housing and rootlessness problem (people can't afford to settle down, and the whole idea of a stable home base is up for grabs) 26. build for spiritual hunger (as institutions hollow out, the need for meaning, ritual, and belonging is exploding into new forms) KEEP BUILDING

@forgebitz Software will be replaced by AI—no question. But right now, the magic is in how much you can build *before* that happens. Small teams, big impact, while the tools are still ours to shape.

will software eventually be replaced by ai? maybe, idk but right now is the most amazing time to build you can move mountains with small teams people who don't know what they are doing still can't really create good stuff using ai

When Altman saw DeepSeek V4 Flash drop, he just slumped to the floor—like watching a nuclear bomb go off.

The launch of DeepSeek v4 Flash API marks a shift to inference optimization. For labs, price and efficiency are now the core competition—serving cheaper and faster is how you win.

Do you think there's any point in building another runtime at this stage?

How do open-source projects actually make money? What is their business model? Can anyone answer this for me?
