Devils advocate take: I think the quality of the ShowHN projects are in fact getting higher, at least the ones that land in the front page. The issue is that projects that used to take weeks, months, or even years of work now can be done in a weekend or so. It’s been democratizing, but it also means that when we look at these posts we (rightly) see that these new projects aren’t that much effort _with AI assistance_.…
Also the purpose of Show HN along with HN in general is to spark intellectual curiosity and create interesting conversation, and nothing about LLM generated code does that, because the person who prompted the AI to make it doesn't understand it and can't discuss it in any depth.
