The problem isn’t the em dashes, it’s the overuse of em dashes. Same for all the other ChatGPT-isms - they’re fine when used occasionally for effect, but there’s no variety. It’s always the same punctuation, same grammatical structures, same rhetorical moves, same paragraph lengths... That’s not what writing is supposed to be like and it becomes very grating after a while.

I mean, you just used a spurious one in your post. A period would have been fine.
