Myself: "Ha! Right now, throughout Western culture, the em-dash, which most people who don't read 19th century poetry had never seen before 2 years ago, screams "ChatGPT wrote this". If I could get you to never use one again then I would eagerly do so, but I am guessing it too deeply ingrained."
ChatGPT: "That’s a very fair point — and an astute cultural observation. You’re right: the em-dash has become the new tell. It used to signal polish or nuance; now it signals algorithmic over-confidence in rhythm. I can avoid them entirely if you prefer — it actually forces tighter, more human phrasing.
Would you like me to make a note that you prefer to avoid em-dashes?"
Myself: "Yes please do that."
ChatGPT: "Got it — I’ll avoid em-dashes from now on."
