“No em dashes” is hard coded in my pre-prompts. I’m with you. It’s fine occasionally for a human to do it but it messes up screen readers and TTS because they don’t even pause. They treat it like a hyphenated word.

AI writing being easy to detect is a good thing IMO. I personally won't read anything from someone who thinks it improves their writing

Except, as is often the case, it’s not that AI itself is easy to detect, but that bad uses of AI are. You are almost certainly reading far more AI generated text than you realise it just doesn’t register as such.
