Turns out "its just an experiment, you all are overreacting" was just a lie to damp criticism. https://news.ycombinator.com/item?id=48019226

I'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 server side JS community for some reason is already used to breakages all the time.

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

The follow-up PR removing the zig source files being auto-tagged by bun's own CI as "ai slop" is so funny https://github.com/oven-sh/bun/pull/30680

This 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.

Why didn't they ask Claude to remove all of the `unsafe` at the same time??

If this goes wrong even in the slightest , the ridicule about a drug dealer getting high on their own supply will be neverending and grim.

PR 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. 1 009 257 lines added 4024 lines removed 6755 commits 2188 files touched 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.

vibe coders keep saying that now you can have 100x productivity, that you can write a million lines of code in a week and do what would take a team of 10 experienced developers a year. where are all these million lines vibe coded projects? I don't see them. its all hype

>No async rust. I wonder why does that deserve an explicit statement? Is there anything wrong with async rust?

I hope the Deno lot take the opportunity to capitalise on this

Rust, Zig and TS went into a bun... /s

How they gonna do refactoring, bugfix or other maintenance on generated code? Ask LLM?

$ grep --exclude-dir=.git -r 'unsafe {' | wc -l 10465 Nice.

Now translate it into zig!

So the geniuses in the datacenter prefer to rewrite the full codebase in another language instead of maintaining and improving its own fork or contributing to make the current language better. Impressive to rewrite 1MLOC in a week yes, but this is more of a job of a million monkey programmers crammed in a datacenter than a bunch geniuses. And I would know, since I'm a monkey programmer who is in danger now... Or maybe the Zig team is in a greater danger, since their brains hold the genius juice the clankers are missing and they should have it by 2027...

Deno's approach from the beginning seems to have proven out.
