I'm not going to bat for GPTZero, but I think it's clearly possible to identify some AI-written prose. Scroll through LinkedIn or Twitter replies and there are clear giveaways in tone, phrasing and repeated structures (it's not just X it's Y).

Not to say that you could ever feasibly detect all AI-generated text, but if it's possible for people to develop a sense for the tropes of LLM content then there's no reason you couldn't detect it algorithmically.
