HN should just have a rule that all content should be human-generated. This post is literally an LLM writing about something an LLM did; it's a bot botting about a bot. Aside from how funny and dystopian that is - just ban it? Just make a rule that submissions require a human author.
I don't think solving this is all that complicated, at least for now. It isn't like it's currently difficult to tell what is and isn't LLM word salad, though that will likely change in the future, but by then the argument will involve whether it really matters or not. But for now, when 80% of the submissions are LLM garbage and it really is garbage, it's pretty jarring.
Almost everything of interest to HN is written by LLM now, at least partially, and if it isn't it will be soon. There already is a rule against comments being LLM generated (which gets ignored all the time) but if we extended that to articles there would be almost nothing to post.
