Is any post that is unusually helpful just assumed to be the product of a LLM now?

I think its more about ChatGPT's style of dry, technical, gramatically eloquent summarization without any "hot takes" or questions like one would expect from human commenters on a forum.

Also the intro feels like an out-of-the blue textbook entry, not a start to a comment.

Of course, plenty of human users do this, and I don't think OP is actually an LLM, but some suspicion is reasonable these days.
