Look, I understand being skeptical of the whole process; the discourse about this has been extremely tiring.

But at some point if “moving one of the biggest actively maintained and used codebases to it without anyone noticing” is dismissed as “it doesn’t mean all that much”, then we’ve lost the plot a little bit somewhere.

It's the equivalent of porting Unreal Engine 5 to another language and then using it exclusively to run a 2D Tetris clone. Let's wait for the next Bun release when more real-world code is hammering it before declaring victory.

(also, fwiw, a manual rewrite would be under the same scrunity and suffer from the same skepticism, at least when obviously rushed).

If you ported UE5 to, idfk, Malbolge and ran Tetris on it and someone would dismiss it as “not impressive”, I would think they lost the plot too!

LLMs are very impressive. Five years ago, the idea that we'd have software that you could ask - in English, mind you! - to rewrite an entire server side JS runtime and you'd get something which even kind of worked was squarely in the realm of science fiction. But the question isn't "is this impressive?", but rather "should the results of such a rewrite be relied upon?" (and specific to this thread, "is the fact that a use case which only touches a small subset of the features of said result appears to no be completely broken good evidence it should be?".

If you could successfully write Tetris in Malbolge, I would call that impressive indeed. Just writing Hello World was a major effort IIRC. The nature of the malbolge interpreter makes it more of a cryptography exercise than a coding one.

		I'm gonna jump in here with some self promo - back in college I TA'd a class that, for a few weeks, taught Malbolge, and the only assignment was for students to write a program that printed their name. After spending a lot of time thinking about the language, I came up with a relatively simple algorithm based on the language design - there are a few operators that mutate state, so basically just try combinations of those until your next memory cell contains the thing that you want, then lock those instructions in and advance. Basically RNG yourself to victory. The original code for that algorithm is here (python, + my own interpreter): https://github.com/wallstop/malbolge-toolkit/tree/dd942fb981... I've since llmified it as an exercise. BUT! The whole reason for this comment is to nerd say that printing stuff is relatively easy if you invest the time in learning the language's primitives and think of programming in it more as algorithms to operate on the op codes instead of literally writing code. Now, to do more interesting things other than printing - I'd have to spend even more time thinking about the language, which I don't want to

You just compared Rust to Malbolge :)

You have absolutely no way to know this though.

Is it though? What’s your source for that data?

This is akin to saying "we replaced the tires on the car and the average user didn't notice". If the entire car was replaced, then maybe we get a bit more excited.

However if "replacing small sections of code" is heralded as "the most amazing achievement in software development" then we've all lost the plot a little bit somewhere.

It makes sense both ways, no?

The reality is, of course, most people aren't going to notice. If the functionality and performance is 1:1 why would they? Is it impressive? A bit, but not how you're positioning it. People seem to forget LLMs are good at what they've learned from training data. And the LLM is good at compressing time. The only notable thing about these types of marketing spins is that a rewrite was accomplished in a small time frame that was hard to pull off before LLMs. The actual act of the move is less so.

Did the codebase improve? Is it more performant? I've seen nothing to really stake those claims with any objectiveness. Lastly: what was gained?

Why is porting a program from one language to another seen as some great achievement? We had f2c in the 1990s.
