alt Hacker NewsIt’s made absolutely no negative difference, as we’ve seen in the real world in the last 60 days since the merge.
I feel weird having to defend reality; reality being that it was merged nearly 2 months ago and tons of people have had their pitchforks out without a shred of actual evidence that this made bun worse in any measurable way. But they still insist it was a mistake.
I’ve never met Jared or the bun team but I don’t understand all the personal attacks, I just feel the need to correct the facts. Literally who cares what language a JS toolset is written in?
It’s not like they ported JavaScriptCore (the actual JS runtime) to rust even. All that stuff is largely untouched.

Anthropic, apparently, not the least because they blanket-closed all issues submitted before the rewrite. If the language were irrelevant, it shouldn’t matter for the existing unfixed issues.

This is even more interesting given that prewar Bun was not a well respected code base. This matters if the code was bad, were the tests bad / not comprehensive as well? If so, the translation to rust whose sole / primary target was test-passing will have a fair amount of undocumented bugs in it.

The crux is:
> What is the governance structure for Bun by the way? Couldn't find any documents/explanations about how it's supposed to work. I'm guessing it's essentially just "Anthropic decides what gets done and accepted" today?
And this is a valid question. You are not "defending reality" by refusing to listen to it.
In summary and based solely on my understanding:
- Jared misled people about the intentions of the migration. It's not the worst thing in the world, but it's certainly worthy of criticism.
- Jared has commented before about locking out human contributors from open source projects. Whether he was making a larger point is irrelevant as his comment stands on its own.
- Other Bun contributors, past and future, outside of those employed by Anthropic, did not and likely will not have equal access to the model Jared used for the rewrite.
Jared, working in the public Bun repository, used tooling not available to his community to experiment with a signficant migration. He dismissed all concerns and told people it's just a bit of fun, and that it shouldn't be taken seriously. Most of the controversy would have been avoided were the experiment done in private.
None of this is a big scandal but questions about the project are entirely justified.
> that this made bun worse in any measurable way
Issues on GitHub was mass closed claiming zig is no longer relevant without fixing the real issues.
this whole AI era has put the topic of "do we believe actual reality, or what we hoped/assumed/continue to insist would be reality" front and center. Every discussion is like this these days.
>It’s made absolutely no negative difference, as we’ve seen in the real world in the last 60 days since the merge.
The rust code is not yet in a stable release, and CC only switched to it in the latest version, so there's not been 60 days of widespread battle testing yet, so i don't see how we could possibly say it will have no negative difference. It hasn't, because nobody is using it yet. It still might.
>Literally who cares what language a JS toolset is written in?
I don't care what language it's in, but i do care how it is written and maintained. I'm not going to trust my projects to a runtime that was written by an LLM in two weeks with practically no human review
The outrage was more how the rewrite was communicated and defended, which was objectively poor.
Except that it hasn’t yet hit the real world, the live release is still 1.13.4, the last Zig version. Anthropic does not operate in the real world.

Maybe you're being coy by asking a rhetorical question you already know the answer to but I'll answer as if you asked sincerely...
There are 2 different groups interacting with software products:
(1) end-users : this is where the "Who cares what language it's written in?!?" is usually applicable. E.g. The finance guys using MS Excel don't care whether it's written in assembly, BASIC, or C Language.
(2) code contributors and/or programming language enthusiasts who see other projects as "validation" of the whatever language they've invested in: these people definitely care.
For all the decades that computer languages have been debated, Group (2) will always discuss projects language choices. E.g. reddit.com switching from Lisp to Python, the Linux kernel fiercely debating future Rust contributions , the Typescript compiler switching from Javascript to Go, Bun switching from Zig to Rust, etc.
People try to lecture others in Group 2 about "don't make a programming language your identity" ... but people are human and they can't look at all the above language choices as totally detached observers. They like to talk about it!
If one is a Zig coder that contributed to the previous Bun Zig codebase, we can't expect them to be neutral observers.
