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?")
