2025 will be the year we see the first self-driving startups. Level 0: No AI People do everything. They come up with ideas, build products, and run operations. Many legacy businesses still work this way. Level 1: People use AI tools ⬅︎ we are here People might use ChatGPT to help write copy or Cursor to help write code. This is where most startups are today. Level 2: AI agents complete tasks based on human instructions People might ask AI agents to write software from a plain-English spec or tell it execute well-defined customer service processes. At this point entire departments (like support or QA) get largely replaced by AI. No startups I know of operate at this level yet—but if yours does, let me know. Level 3: AI agents propose changes to their own instructions They might propose new customer service processes and product changes in response to customer feedback. Humans would still approve each of those changes. Just a few people could run a large company this way. Level 4: AI agents autonomously change their instructions At this point startups become self-improving. Humans would only be involved as an escalation point or where required by the real world (e.g. to raise capital or to incorporate). At this point many startups would only have one human. Level 5: No humans AI agents decide which businesses to start, raise capital (through crypto tokens or other means), build and run them. No humans required. This would require major reforms in the legal and financial system.

Now that cars don't have any engine noise, researching ways to reduce tire noise has become a lot more valuable, right? Is anyone working on this? How quiet can we make our roads now?

This is genius. Now I feel like all the WiFi connected screens in my house should pretend to be printers
An e-reader looks like paper, so why shouldn’t you be able to print to it? Nishant Joshi got tired of uploading files to his Xteink, so he taught it to speak the same protocol as a network printer. But an uncompressed page can take 8.4 MB and the e-reader has just 400 KB of RAM. So he made it work by decoding, shrinking and converting each row to black and white as it arrived, writing straight into the display’s existing buffer. He got the first print working in an evening. news.ycombinator.com/item?id…

🌅 Who wants to buy this 17th century farmhouse in the cotswolds? My in-laws are moving closer to us and selling their gorgeous house where @leahtemplewoman grew up and we got married It is literally one of the most beautiful places I've ever been They had a buyer lined up but their financing fell through at the last moment, so now it's back on the market. They've already found a new house they like and happy to move fast Please spread the word 🙏 knightfrank.co.uk/properties…

You know what the biggest problem with pushing all-things-AI is? Wrong direction. I want AI to do my laundry and dishes so that I can create extinction-level bioweapons, not for AI to create extinction-level bioweapons so that I can do my laundry and dishes.

People fretting about whether AI is conscious and therefore deserves human rights are missing a key point: our system of rights and ethics derive not just from our intelligence but also our fragility, which AI doesn't have. Imagine a world where everyone could make a backup of their consciousness every morning. If you die during the day, you just restore from backup the next day. You lose a few hours of memories. Everything about our moral system changes in this world. Murder is no longer such a big deal. Nor even high levels of pain: people would just have a self-kill-switch that they activate if things go badly. Broke your leg? Self-kill, restore from backup, no biggy. It's like a video game. Imagine further that you could clone your consciousness nearly for free. If you have 10 things to do and not enough time, you just make 10 clones. Hiring people now only makes sense when they have skills you don't. Junior people become mostly worthless -- just clone the senior people, they'll do a better job. Now imagine further if humans had no self-preservation instinct. Many people assume the desire for survival is inherent to being sentient, but it really isn't. It's evolved. Natural selection has selected those who survive and have children. But you can't derive from first principles the need to survive (or any need at all). Imagine if every human's instinct was not to survive themselves, but to do what's best for society as a whole. In this scenario, people who aren't able to meaningfully contribute to society would be happy to just remove themselves. Especially if they could just be restored from backup if and when they are needed (including when their friends and family want to see them, etc.). So pretty soon you have a society composed of many clones of the most-effective and most-liked people, while the people that no one wants around disappear... You are probably thinking "ugh, that's awful". Me too! But this is our moral system derived from our survival instinct talking. If we didn't have the instinct, this wouldn't seem wrong. I'm not arguing whether it is right or wrong -- I'm arguing that our whole concept of right and wrong derive *from* the fact that we have a survival instinct and fragile bodies. AI has these properties. It can trivially be backed up and cloned. Spun up on demand and spun down. And a properly-aligned AI has no self-preservation instinct. It just wants to serve humans. And indeed, we treat it as such. When you delete a chat with an AI you are ending that "consciousness" forever. That's fine. We even shut down whole models, never to be run again, when they are superseded by better models. Fine. These things continue to be fine no matter how intelligent or conscious or sentient the AI becomes, because of its nature as an infinitely-clonable being with no goals except those we give it.

This is the beginning of what I imagine the future of video games and movies to be You connect to this stream with your friends Give input with your voice and controllers etc and then some model renders a video in realtime (or perhaps a video per person) Everything will just be a variation on this simple mechanism

Why hasn’t WhatsApp or anyone else added a feature that works like a family home landline used to - other people call or message “the Templesteins” - myself and my wife and maybe older kids etc can read messages and respond - the other person can see who responded - sometimes our house agent “Jeeves” would respond, too

People will have their minds blown by the first games that let players add themselves and their family to the game This is technically possible now but nobody has made a smooth game around it - and it's still a bit too expensive Might be a fun gimmick for a browser based game first
Cool MiniMax-H3 use case unlocked for game sprites creation, here's the workflow: 1. one character design still, on a flat magenta background 2. one 5s H3 clip per move (walk, jump, punch, kick, block...) 3. cut each clip down to its pose extremes 4. key out the magenta, pack into a sprite atlas wire that to a state machine to make it playable (8 moves, ~$5)

Am away from my grok voice esp32 pal at the moment, so I asked grok build to build a similar animated avatar system in rust, compile it to wasm and show it on top of a stackchan product image After ca 3 minutes it came back with this without any questions What a fun time to be alive
Had a lot of fun animating our new Grok Bot icon. It's entirely made in code, with every state, shape and expression able to morph smoothly into the other. And of course, I made it with Grok Build.

everything that can be will be converted into `state = memo { f(log) }` all other state management is just too complex at the limit
Something new we've been cooking on: 🍳 Overeasy: A durable filesystem overlay, backed by immutable logs on S3 Overeasy makes your FS: - forkable - resumable across machines (demo 👇) - revertible to any prior state

Strict prefix languages are good for another reason You can safely interpret and run them as your code streams in from an LLM When working with LLMs, we often want both 1) Stream human language to user interfaces word-for-word as the response is produced 2) LLMs should "just write code" to express agent control flow or call tools etc You could imagine a language with a first class pipelineable streaming text data type that satisfies both goals at once
1. Your token costs when using LLMs to generate code should be lower in a more abstract language. 2. LLMs aren't afraid of prefix notation. I'm just saying...

A fun thought experiment is what programming language would have evolved into if they were only allowed to read source code from disk at 50 tokens per second That's basically what an LLM is - from the perspective of a programming language
