The danger in AI-assisted coding is confident blindness. The best way to help students, users and developers who building with AI is to convert more of their "unknown unknowns" to "knowns unknowns". Only once you know there's a problem can begin solving it

Someone said “oh you’re arkangelofkaos” and now that is going to live rent free in my anxiety brain for the rest of my days.

Great metaphor for working with agents: your brain is a sponge that gets ringed out every hour or so. Soaking in context, working with it and then offloading context has a cost for organic neural networks!

Was really enjoying Stray... but then got hit by motion sickness :( www.youtube.com/watch?v=nb0q...

having used claude extensively for the past couple of months, i think there is still a lot of value to understanding your code and steering it intentionally. the amount of incidental complexity claude accumulates otherwise (which mostly results in bugs that it can't ever fix reliably) is staggering.

I hate the re-soloing of development. We were so close to learning social skills, creating community, encouraging creativity & purpose, & applying empathy. Easier to manage if each of us is so busy with our genieswarms that we don't have time to talk & reflect.

Thanks to everyone that joined us for @xtclondon.bsky.social on Tuesday! Loved all the discussion sessions on enjoying programming, effectiveness of AI, security and "best vibe engineering practices" 💪 Looking forward to future meetups: www.meetup.com/extreme-tues...

Short musings on "cognitive debt" - I'm seeing this in my own work, where excessive unreviewed AI-generated code leads me to lose a firm mental model of what I've built, which then makes it harder to confidently make future decisions simonwillison.net/2026/Feb/15/...

Join us tomorrow evening and chat with us on how you're using LLMs, including automating writing awesome documentation with @nearestnabors.com! We will be at the City Pride, sign up now: www.meetup.com/extreme-tues...

Excited to discuss all language models, large and small, with y’all! Happy to wax lyrical about Vercel’s AI SDK! Seeking counsel from other vibe engineers out there 👍

Late notice perhaps, but we're back in the loving embrace of the City Pride on Tuesday next week (20th January)! Come along to chat with your fellow humans about working with humans and machines. www.meetup.com/extreme-tues...

Getting 408 errors calling the OpenAI API on Microsoft Foundry using fetch in Node? Try using the official Node library from OpenAI instead, it’s configured such that it prevents the default 60 second timeout!

the hack to being productive with claude code is to start the project with great e2e tests that are declarative enough that they let you precisely specify behavior without saying too much it's really magic

On the Eighth Day of Christmas, I made 3 spelling mistakes and had to restart 3 times. Now I wonder how many older ones had spelling mistakes and I simply didn't notice.

Vibe coding is irresponsibly building software through dice rolls, not caring what code is produced What about when engineers at the top of their game use AI tools responsibly to accelerate their work? I propose "vibe engineering"! simonwillison.net/2025/Oct/7/v...
