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?

One way to use em-dash and look human is to write it incorrectly with two hyphens: --

I still use 'em. Fuck what everybody else thinks.

At this point I almost look forward to some idiot calling me AI because they don't like what I said. I should start keeping score.
