Deno was already implemented in Rust, and not done by vibe-coding. Would you trust a fully vibe-coded runtime? Not some features, not some fixes, but a full translation from one language to another.

We had Fortran converted to ADA semi automatically at a place I worked. We called it Adatran. That code was weird and very hard to maintain. That goodness it was just small functions.

This is my fear wrt Bun. That they have translated Zig into non-idiomatic Rust.

If it has tests and responsible management, sure why not. I generally feel more comfortable if something is 1) widely used & scrutinized 2) managed competently. But that's orthogonal to how (not if) people use AI. Having good tests, reviews, etc. is much more important. Do people trust random NPMs developed by random people on the internet? Apparently we do given all the recent issues with supply chain attacks. I hav…

The problem is that we are not talking about an application but a runtime. A bug in the Bum platform can have much more serious consequences than in a lone app. Unless there is a deep thoroughly review by the maintainers, I wouldn’t trust it.

Another great example of Averse Ai Behavioral Syndrome If y'all ever wondered how your dads got sucked into alt right talkshows and radio, just read ops comment in Tucker Carlson's voice.

One difference between programmer and engineer is that the programmer worries about what they do, while the engineer worries about not only about what they do, but about the platform their application run.

And you bringing the fringe entertainers of the illiterate Americans is totally unnecessary.

You're just speaking in truisms, and still have yet to assert anything at all. You sound more like a fringe entertainer and less like an engineer. You're, "just asking questions."

Are you an engineer? Make clear claims, and then back then up crisp and concrete arguments. Support your arguments with data. That's engineering.

What you're doing is wallowing in the outrage machine. Please start with your indepth understanding of the bun runtime that qualifies you to comment on the overall quality claims that you have not yet made but have insinuated.

Please clearly cite your concerns. Please present a cogent and articulate analysis of the overall shortcomings, gaps and potential threats of the bun rewrite.

Let's have an engineering discussion.

I do love how everything is always “vibe-coded” regardless of any amount of effort, collaboration, or oversight that may have gone into the use of any AI. It really captures the nuances of the conversation.

What has not been talked about here yet, and which isn't directly about AI, is this: "The benchmarks are neutral-to-faster, and the binary shrank by a few megabytes"

This says more about Zig versus Rust, and I was surprised by it, that a "direct translation" of this kind would give a somewhat faster and smaller binary.

They obviously haven't closely reviewed the code. That's the point

Why is that obvious? Wouldn't surprise me either, but I don't think it's obvious, unless I missed some "confession" or something.

It's 1 million LoC they merged in a week. And that's only the final state. It's going to be much, much more if you include changes in individual commits. 6,755 commits were pushed to the PR branch, including dozens that were made shortly before the branch was merged to main. There's not a chance that anyone has read the code in any significant portion, or even in the future, because people who review code don't merge to main before they do so.

If you ran that converter multiple times, did you get the same output? I think that's the crux with automated codebase conversion via LLMs, I'd really want to focus on making everything as reproducible as possible first, not use a general agent and just vibe it together.

We’d get the same every time. It wasn’t great but it did work.

Would you vibecode a house?

Yes, absolutely. In fact that's a big feature now in Autodesk. 99% of the design of a house is "detailing". Where does power line #8128 go? Does floor section 38 have the right slope? How big should water line #92 be and does it fit with sewage line #33 while it's sloping in the correct direction? We can't get electrical socket type 33, please modify everywhere in the design so we can use type 35 instead. And so on a…

> Also if vibecoding houses can lead to a large increase in housing supply, as it should: Hurray!

I love how well this captures the credibility of zealots and how some won't hesitate to exploit human suffering to push an agenda. The housing crisis is driven by regulation that lowers supply, shaped by greed and cruelty. Turning house designs into slop won't solve anything.

You want to see how AI actually contributes to the housing crisis? Then here's an actual example:
