They're just so handy! I do think LLMs tend to use them in a specific way, though.
So maybe tweaking your usage (ex. no spaces around them) or using a technically incorrect en-dash might offer the desired effect while subtly signaling that your message isn't AI-generated.
I still use them — mostly for pauses — but I'd like to think my voice sounds distinct enough from an AI that people can tell.
I for one am striving for clarity and couldn't care less about being confused with AI.
However I've only ever used regular dashes. How do you type an em-dash? Is it OS specific? I've taken to using Emacs insert-char with a list of frequently used ones in my scratch buffer. My memory for Unicode is unreliable.
I've only ever been using "regular" dash, a minus, for that. How do you even type yours? If I ever needed differently-sized dashes (and I don't know the difference between them) I always used wiki to copy them.
(disclaimer: I feel like this obsession with dashes is special to native English speakers, which I'm obviously not)
