It's not even about em-dashes. There is a certain flow in AI writing that is blatantly clear. It writes. Like this. Always short sentences. With a punch. Line.
People, don't let AI rewrite your stuff. I would rather read grammar mistakes... I know that I have problems with runaway sentences, long paragraphs, etc. But honestly, I feel like nowadays, that is not even an issue, but the only sign that shows I'm human.

I don't see this lasting. Industry will always autocorrect, and people want something better. The question is how long.
@Corty
em-dashes, I read it not as an indicator of A.I. anymore, just the author didn't read their own book. coz if they read it they'll go there is a self-inflicted breaking of flow every 5th line, and this is not a good experience.
