notice something? Linear, PostHog, Attio - all shipped the same thing in the last few weeks. Homepage is a chat bar - not a dashboard. This is the SaaS industry quietly admitting that traditional UI doesn't work anymore. Every user is different. One homepage can't serve them all. The playbook is shifting: → expose your core APIs → connect an agentic layer → let users use software the way they want SaaS became chat. Chat will become Generative UI - the agent won't just reply in text, it will compose the interface itself. We're closer than people think.

Wow, this tweet went very viral! I wanted share a possibly slightly improved version of the tweet in an "idea file". The idea of the idea file is that in this era of LLM agents, there is less of a point/need of sharing the specific code/app, you just share the idea, then the other person's agent customizes & builds it for your specific needs. So here's the idea in a gist format: gist.github.com/karpathy/442a6… You can give this to your agent and it can build you your own LLM wiki and guide you on how to use it etc. It's intentionally kept a little bit abstract/vague because there are so many directions to take this in. And ofc, people can adjust the idea or contribute their own in the Discussion which is cool.






everything is programming




Unpopular take: You should learn more programming. Take more courses. Watch more videos. Practice by hand. Read books. Yes, freaking books. Even if, and especially if, you are using AI to do most of the work. Do it in between instead of scrolling f*ing TikTok. Do it at the gym on the bike. Do it at night. Do it whenever. Focus on things you can't do well manually yet. Study other languages like Zig and Rust. Get really good at React and Typescript and other things you use all the time in your projects (whatever they are, these are just examples). Study the various libraries and the choices those developers made. The more you understand, the more you can guide the AI. And you will make stronger architectural decisions and spot security issues and bad coding practices that you can overrule as you shepherd your AI sprites.

This is a great report on the state of software and AI by @Redpoint - thank you, @loganbartlett! Where I disagree is the build vs. buy slide: 1) I'm not sure if it takes ~12 engineers to build/maintain a Slack clone for 1 customer. As AI keeps getting better at not only code gen but all software engineering tasks I think you'll be able to do it with a smaller team. Doesn't mean you should spend engineering time on it because I expect... 2) ... there will be agencies who specialize in this kind of work (e.g. build a Slack clone and sell customized versions of it). 3) ... there will be lots of cheap, (more or less) good enough Slack clones 4) ... there will be AI-native startups that rethink the category. All of these factors, I think, will contribute to pricing pressure for Slack and other traditional SaaS companies ... which they will only be able to defend against if they get a share of the agentic revenue enabled by their products.
