I think people are retconning a lot of things onto Show HN that aren't actually part of the ethos of Show HN. That's not new; in the past, people have tried the same thing to suggest Show HN is about, say, open source software only.

I don't dispute the quality decline on Show HN or the need for some kind of intervention, but this particular argument about how AI interacts with "Show HN" is in fact introducing a new and significant element of gatekeeping to it.

Show HN is not in fact a craftspersons forum! Craft can be one of the things it's about, but it's not the only thing.
