“+1,000,000” changes in a single commit is insane.
And 6700 commits.

#22PR so thick, the page failed to load the first time I opened it, and the comments still continue to fail to load. Absolutely hilarious. Though that may be just GitHub having a normal one, hard to tell these days.

I haven't the slightest clue how anyone would even remotely hope to review this. I guess by just using even more AI? Or maybe by throwing some über hardcore lint pass onto it? It really seems like more an exercise in risk assessment than code review.

#23This will go down in history as the biggest mistake of software engineering of all time. Bun is the runtime of Claude Code, which is the core product of a trillion dollar company, which now sits on a vibe-coded app, where not a single person in the world has a proper mental model of.
I don't know, there's been some pretty bad software mistakes, possibly bigger than a PR to convert an app to Rust:

"We haven’t committed to rewriting. There’s a very high chance all this code gets thrown out completely."
People conflate “high chance of X” with “X will happen” all the time. See elections, for example.

I for one am REALLY GLAD to see it consumes itself.

Maybe this is the best marketing trick for Claude Code ever. Maybe there was pressure from Anthropic to do this and prove the value. Even partial success is enough to prove the value, justify the value and usage, and AI dependency even further.

Re: Rewrite Bun in Rust has been merged
#28I'm actually excited for somebody trying experimenting with automated translation, but I'm afraid this will be lots of backwards compatibility issues. I started looking at the commits, and it's basically solving the ,,tests not pass'' problem by changing the tests themselves. The real work of making it working on programs that are already deployed will be just starting now. The only silver lining I see is that the se…
I doubt it will end up as stable release very soon, but I'm happy to be proven wrong. I have some skepticism about this whole rewrite, Jarred Sumner has enormous internet following and it feels like an ad.

My initial reaction was that this is pure insanity but in fairness this is a fairly 1:1 port of existing code, so the developer's mental model of it should still match fairly well.
For instance look at this Zig function: https://github.com/oven-sh/bun/blob/ed1a70f81708d7d137de8de0...
Versus this Rust version: https://github.com/oven-sh/bun/blob/ed1a70f81708d7d137de8de0...
I did pick that at random but it does look like the best case. I skimmed through a lot of the Rust code and there's a surprisingly small amount of `unsafe`.
Still pretty insane to merge this in such a short time with so little testing, but I can easily think of bigger software engineering mistakes. Hell it's not like Bun even needs to be commercially successful any more.
