How is it unprofessional when it is simply someone giving their honest personal opinion on an issue that involves something that is valuable to them, on their personal blog nonetheless. Is everyone a walking and talking brand now so that they have to always filter their words, walk on eggshells, hide behind corpo-speak so as to seem 'professional'? More honest discourse is required in today's world, not less. It seem…

Nah, corpo-speak is the original slop. The result of too many comms/legal inputs to a conversation.

Professional communication is direct, clear, and ideally courteous (but only to a point).

The people who steal with AI and give no credit to the actual creative forces (that they are stamping out) are the fucking rude ones. I just return to them the kindness they show me when they say, "You made this?? I made this!!"

I understand your anger too. AI did steal open source knowledge, and I agree with that part. But separately from that, I think it's a bit unfair to talk about the people associated with it in such a dismissive way. In reality, humans aren't purely rational beings, and I can understand why the Zig philosophy and the Bun manager who joined the AI side might not have looked good from that perspective. But I think that's…

> AI did steal open source knowledge

It's really sad to see my fellow FOSS enthusiasts adopt this very strange vocabulary from the anti-pirate people. No, no one has stolen anything, the knowledge is still out there. No, you cannot even "shameless copy" from something that is asking the world to copy from it. Literally the point for me and others is that what we put out can be used by anyone for anything, that's why we use FOSS licenses in the first place.

I have learned so much reading Andrew’s code and as I said in the original post: Bun would never have happened without Zig.

> The post claims they were fuzzing their Zig code, while during our calls the whole Bun team told us that they were not fuzzing anything. This appears to be an outright fabrication.

Fuzzilli integration: https://github.com/oven-sh/bun/pull/24826

Merged PRs fixing issues Fuzzilli found in Bun’s Zig code:

Am I right in thinking the Bun rewrite hasn't actually been released yet? There was a big kerfuffle when it was merged to master and people seemed to be behaving like that meant it was all done and dusted (as does this article), but it looks like the last release is still 1.3.14 from April so presumably general users are still on the Zig version? Is there a timeline for release?

It's shipping soon https://bun.com/blog/bun-in-rust and has been shipping in Claude Code for the last three weeks https://bun.com/blog/bun-in-rust .

> It's insane to me that Andrew thinks this post will somehow exonerate Zig when it really just makes them look childish. Antirez made a post equivalent to: you'd be a fool not to use AI to increase test coverage. Zig on the other hand has embarrassingly low test coverage given its adoption and time in development. Their stance on AI is completely childish. They could benefit massively from it, yet refuse to even con…

I am fine with people having principles and doing things their way. Not everything has to be a race to be the best. There are still plenty of people that appreciate traditional crafts. Anyway, if Zig+AI can be the next, greatest thing, can't someone just fork it and make it happen?

People are doing the simpler thing: moving ecosystems more suppotive of their goal.

Disclaimer: I'm bullish on Rust. And I think LLMs are overhyped, and kind of overhated.

Honestly, I think it would have been better if he had done the smart thing and ignored the noise around Bun's Zig -> Rust, and focused on code.

If he was willing to ride the coattails of Zig being hyped by Bun, then he should have taken the hit when Zig and Bun parted ways.

Hell, if he is that happy that they are leaving, he shouldn't have written that he is happy. Just smile and wave...

So now Jarred wrote a very matter-of-fact post about migrating Bun to Rust, and Andrew Kelley wrote a ranty blog about Jarred sucking at Zig, and being glad he's gone.

Andrew's online social behavior is largely a streak of pettiness imo. This is not even close to the first time I've seen him write something I felt was overtly mean spirited, not just euphemistically "blunt". "Was silence not an option?"

i watched a youtube video where he called out people as garbage programmers... i felt that was petty, his streak continues i guess

Could you please link the YouTube video? I tried to search but couldn't find one with "garbage programmers".

Never heard of Bun or Jarred before today I enjoyed his blog post about the migration to rust, it is an impressive feat if real ! I didnt see anything bad about Zig in the post, on the contrary it shows respect and that big projects can be done in Zig

Next, I read Andrew's post, and the thing I see is: Jarred looks like an achiever, Andrew more like a butthurt childish whiner I also can see why Jarred made the migration, it is not only technical, and it was a great call IMHO

There are astute comments about the post's tone elsewhere in this thread[0] But this killed my hopes for Zig. The drama is fun, and Andrew is maybe even admirable in his earnest, but this just isn't the kind of professionalism needed for a serious project. I know that's boring and uninspired, but that's what I want my tech stack and it's management to be. Also, maybe Jarred was a net negative, but bun was also a real…

Yes, I think you are totally right. I'm sure Linux would never be so big as it is without a maintainer that talks so professional than Linus Torvalds.
