To me, this whole effort of rewriting Bun from Zig to Rust looks like a big marketing move. The question is: if Anthropic AI is really that powerful, why not just fix the bugs and give it the more ambitious task of redesigning the existing Bun Zig codebase in a way that eliminates not only the current bugs but also prevents similar ones from happening in the future?

zig doesn't accept ai written code

How is Bun codebase connected to Zig codebase?

The sole reason for that rewrite was Zig creator announcing he won't be accepting AI contributions. It hurt Anthropic's feelings.

You can't do "redesigning the existing Zig code in a way that eliminates not only the current bugs but also prevents similar ones from happening in the future" without actually changing Zig itself.

Zig is getting that Elm, etc vibe. Genius/visionary BFDL who's also personally incapable of leading the project towards healthy long-term viability.

Say what you will about Matz or José Valim, I don't think they'd ever write a "and don't let the door hit you on the way out" screed full of personal attacks ("stinky manager", "writing slop", "a total shit show") against a person who led a very prominent project and financially supported the language.

well, for me personally, "the" Zig project is not Bun but Ghostty, and it always has been.

yeah, Mitchell is very pro-AI, but he is thoughtful, and he sometimes highlights the difference between Zig's and Ghostty's approaches to LLMs (outright ban vs taming)

> So, when the Anthropic aquisition finally happened, we at ZSF breathed a sigh of relief. When the donation silently stopped, our bank account was ready for it. When they neither canceled their monthly meeting with us, nor showed up, we were not surprised. The relationship was over.

Seen this time and time again, project/organization gets taken over, and everything "good" they did doesn't get exited with fanfare or anything, just silently dropped as your benefactor starts silently ignoring you.

I'm really happy they saw the writing on the all and were prepared for the inevitable, a really great lesson you shouldn't need to learn yourself the hard way, and FOSS project relying on one/two big donators should take heed, we'll see a lot more of this in the developer tooling ecosystem moving forward for sure.

Is the bun rewrite actually done? There's no tag for the release, and as it stands robobun has almost 1.3k open PRs on the repo: https://github.com/oven-sh/bun/pulls/robobun

It doesn't look done.

And it looks like work on the rewrite began in early may: https://github.com/oven-sh/bun/commit/46d3bc29f270fa881dd573...

So... its more like a 2 month rewrite that is definitely not done yet????

It feels like the first half of blog post is less of "thoughts on the Bun Rust Rewrite" and more "I don't like Jarred, he's a bad programmer and manager". Maybe I'm wrong, but it strongly feels this way. I'm not saying that Andrew is right or wrong, it's just that you could throw out most of the first half of the post and not lose anything actually on topic. > But having graduated from the Thiel Fellowship school of…

Andrew is right. I’m sure his emotions come through here, but his take on these things lines up with everything I’ve seen.

Same. After following the drama on HN and Twitter it's pretty clear Jarred has been intentionally doing something that's hurting Zig/Bun community. What I've seen check out with those statements in the post
