I don't think OP is guilty of this, but a lot of people think that current AI-generated content is going to sound like something that doesn't know how to be human or what humour is. That's a fundamental misunderstanding, I believe, that thinks that the LLMs that are popular now have any kind of actual sentience, and simply lack experience or understanding.
Fundamentally, they'll instead sound like exactly the most average or boring (but informed) person, except maybe a bit more repetitive, because they're trained on data and not coming up with independent thoughts. Someone who writes in a unique way and has a unique sense of humour is far less likely to be an AI than the average (yet somehow more accepted) everypost.
