Earlier quoted context omitted.
I used to be an em-dash user, but now my opinion is that I’d rather be perceived as someone who does not want to be confused with an LLM. So I’ve changed my writing style.
My feeling is that my writing doesn't sound anything like an LLM, so if someone thinks I'm an LLM because I used an em-dash, that's on them. That, or I royally screwed up and need to do a better job as a writer. At least with today's LLMs.
I'll go a step further: I think I'd rather actively filter out people whose AI detection is that naïve.
