So the "Bun being a vibe coded rewrite from Zig to Rust" is a different story than I think it's being sold as, from everything I can see.

[blogdiva@mastodon.social]

@cwebber that Zig should stay the course and not let Bun nor Anthropic live rent-free in their minds nor repository ―because they will fail.

of course, they won't admit it, but given AIsloppers’ record of debugging, securing and documenting the shit they extrude with AI, someone will need what they originally wanted: Zig.

beside staying the course, they should lawyer up and have them review any licensing infringements.

[gbrlsnchs@hachyderm.io]

@cwebber Who would've guessed?! It's the same guy that wanted to hire developers to work extensive hours a day for the Bun project before LLMs were a thing. Of course that type of people will align with LLM replacing human labor.

@federicomena @cwebber It depends if it keeps the structure that you understand and just does the legwork of the reworking for language; properly guided it may well do that.

[zkat@fedi.zkat.tech]

@cwebber that I'm now paranoid that by "doing research on competing implementations" he means "copycatting Kat's work" and now I'm glad that I've stopped working on orogene in public.

@zkat @cwebber jesus

[zkat@fedi.zkat.tech]

@janl @cwebber I mean not just mine, but pnpm and Yarn’s. The latter is also porting to Rust

@cwebber

The thing I laugh about in all of this, the thing that is absolutely the funniest, is that while these AI generated or "rewritten" projects may be Open Source, it will never be free.

It was created using a sizable investment.
It can only be maintained by additional investment.
No one, external, will want or be able to contribute, meaning no prospect of continuance.

There will absolutely be licensing fees, because money has to come from somewhere, which absolutely undercuts whatever value they might think they're offering. That kind of renders these projects as instant abandon-ware, and any systems architect worth their salt is absolutely going to spot that red flag.

Truly, the learning opportunities are endless.

[zkat@fedi.zkat.tech]

@cthos @janl @cwebber to be clear: I easily share my code with folks. I don't mind the "spirit" of foss. I take issue with having my work thrown into a soulless machine devoid of any of the community I would otherwise be building. I think it's healthy for us to look at each others' implementations and compare notes and have done a lot of that, and a lot of sharing of my own.

but honestly, fuck Jarred in particular. He's always been kind of a dickbag.

[cthos@mastodon.cthos.dev]

@zkat @janl @cwebber yeah none of that was a reflection on you, just "holy shit what a shitshow" from bun / that guy.

[janl@narrativ.es]

@cthos @zkat @cwebber this

[slyecho@mdon.ee]

@cwebber hard for an LLM, but in 2026 these kinds of things are not done just by an LLM. Multiple parallel and subagents using different models, that can reference multiple files and go back and check on these instructions and correct mistakes, investigating changes from git history, running tests, creating new tests, and so on.

Of course, it is all running on LLMs in the end, and using thousands of dollars of tokens. Which he can get for free from his employer, of course.

[ggherdov@fosstodon.org]

@federicomena @cwebber There's also Andreas Kling/Ladybird making similar announcement ~3 months ago. https://ladybird.org/posts/adopting-rust/
You and I have diff views on the matter (I like genAI for code, within reason). I read Kling's move as: I have goals w/ ladybird, ie (1) making a new high quality browser and (2) having as much fun/enjoyment in the process as it's fair. C++ is kinda getting in the way of (1), but manual rewrite is polar opposite of (2), so let's see if genAI can help eat cake + have cake.

[ggherdov@fosstodon.org]

@federicomena @cwebber But Federico's point "I don't understand being the lead ..." applies 5x to Ladybird. For Bun, Christine points out these folks know 100% what they're doing (epic marketing stunt + savage diss at Zig with its no-AI policy). Kling and Ladybird is the "Got no horse in the race, and yet I think AI-assist is the way to go."

[64kb@icosahedron.website]

@cwebber build many to throw away is the slop coding way.

Like LLMs in general it can sometimes be useful, but used a lot of resources, even more if you are not careful.

Still: port from one language to another is something they are at least fairly good for.

[jcaron@mastodon.social]

@cwebber porting Bun from to rust is more than possible, Deno proved that rust is capable of building a JavaScript runtime. I agree with you, it looks like a "big headline" grab in the making.

[cwebber@social.coop]

Update: Merged into main already https://github.com/oven-sh/bun/pull/30412

[xan@xantronix.social]

@cwebber Jesus Christ.

[fogti@chaos.social]

@cwebber It'll get interesting if/when Rust also commits to a "no AI contributions to the compiler + core" policy...
