one weird thing i've noticed about coding with ai: it's so much harder to get and stay in flow state. vibe coding loses my vibe, coding. prompt... wait... review, prompt... wait... all the waiting inevitably ends up with checking slack/email/x/etc.

I still don’t understand what “winning AI” means for a country at this point. But, whatever it means, it’s better to keep China fat and happy than force them to figure out how to copy fast and effectively.

Spent the morning with some Normies. The topic of AI came up. Kinda shocking how much they knew about it, how much they use it, while at the same time, how much was misunderstood and feared. Reminds me of when we couldn’t put our real name online or use a CC in e-commerce.

We are at the point where if you use the right terms in fundraising (“LLM,” “evals,” etc), investors salivate. Reminds me of “web 2.0” and “xmlhttprequest.” Shocking tbh. It’ll revert to caring about creating value soon.

He infected me, too, but I ended up with macOS + AeroSpace + sketchybar. Just the coolest macOS setup I’ve ever had. None of the mess of Linux.
