I don't have strong negative feelings about the era of LLM writing, but I resent that it has taken the em-dash from me. I have long used them as a strong disjunctive pause, stronger than a semicolon. I have gone back to semicolons after many instances of my comments or writing being dismissed as AI.

I will still sometimes use a pair of them for an abrupt appositive that stands out more than commas, as this seems to trigger people's AI radar less?
