Two nights ago, I decided to give Claude Code an actual challenge. I dropped a decrypted copy of Bloodborne 1.09 for PS4 into a directory, started 5 agents and told it to decompile it an recompile as a wasm playable game in the browser. I woke up to this:

Imagine if tools did what their users wanted, rather than some of the wealthiest corporations in the history of human capitalism. PS Infosec works by making tools broadly available for the public to defend itself, not by a priesthood who gets to anoint things as safe.

GLM-5.3 and the spread of advanced cyber capabilities
GLM-5.3 can autonomously build end-to-end cyber exploits, but unlike other frontier models, it was released without meaningful safeguards to limit misuse.

Their advantage is their naïveté. While AI is relatively new to everyone, working without it for this long led us to form strong preconceptions about what AI can and can't do. Young people don't have such preconceptions (for better and for worse).

i think the closest analogy to 'what is going on at AI companies' is 'what was going on at JPL in the 1950s,' where communists, Satanists, swingers and adherents of a bizarre Russian Orthodox-adjacent techno-optimist microsect ended up doing a tremendous amount of important rocket science

This morning I stumbled into @jacob.gold's post on Hacker News (congrats!) and I thought it'd be the right chance to write down some thoughts on open weights and the future of AI:
maffe.is
An open letter to Dario: if you mean it, open the weights!
Any AI model a company offers to the public has to be released as open weights. This wouldn’t cover every model you train, just the ones you make available to the public. Internal and research models…

A common misconception about Bluesky is that it "has no algorithm". In fact it has many algorithms - custom feeds. You can choose which one to use. What does it look like? You can replace the built-in fyp called Discover with a custom For You that runs on my gaming pc in 23 seconds:

hailey is correct. your confidence needs to be in your workflows, not the models. if you can't run your workflows with something you think is dumber than your favorite model for the task, your workflow isn't good enough.
