I have a programming language project: lone lisp. It's on GitHub. I asked Claude to analyze the commit history before and after AI and the result was: with AI I'm committing around 8x faster than before. Lone experienced a literal explosion of features, improvements and fixes after I subscribed to Claude.

And this is the project I care most about. I review every single line of code the AI outputs. I push back on everything it does. I reword every commit message. I make every effort to understand how everything works before committing it to master. I cook branches for days and I don't merge until I think it's perfect.

Still gave me an ~8x improvement.

The latest development: shaped objects, like Self and V8. I asked Claude about it and it just implemented it in like 10 minutes. Boom, instant ~20% speed improvement. I read the code and it turned out to be almost obnoxiously simple. It basically converts hash tables into arrays internally, and deoptimizes back to a hash table if anyone deletes keys from it. I'm still reeling from the sheer absurdity of it.
