You clearly don't know shit about the whole topic, yet attack an open-source project's author who wasn't even the one posting his own project..

> Why would we want the tradeoff where the LLM has to write significantly more code and where the specification needs to be more complicated? If the author is aware of the state of the art then I think they made a poor choice, but that's not the point.

Because code is trivially cheap now. LLMs churn out a shitton of code at pennies, and as technology improves their per-line cost will continue to decrease. A proof has to be written once and it's never read again. It's only important property is that it is machine-verifiable - from then on only the signature matters. Meanwhile speed of compilation matters, so an obvious tradeoff was made by the author.

> my general point is about how people will vibe-code a solution without an understanding of the field, leading to worse results than if they spent a little while understanding the field and then vibe-coded their thing.

This is clearly not the case here, and even if it were, it's still a better thing than vibe-blogging clickbait shit with extra amount of Dunning–Kruger. Calling out an author who clearly works in the field for a decade or more for not knowing the topic...
