@clive I have -- basically since the start of my writing -- extensively used "--", probably more than I should, but it's a habit and narrative style punctuation I prefer. I never actually use em dashes myself, though some platforms will automatically convert "--" to an em dash by default. I mainly edit in ASCII editors, and of course em dash isn't even supported there. I also prefer "--" since I know for sure how it will be displayed to the reader, while there is still less assurance with em dashes. If em dashes are now considered a sign of AI-written text due to their use by ChatGPT, etc., that's fairly hilarious.
