On a Mac, you can use option-shift-dash to insert an emdash, which is muscle memory for me.

If I had used an LLM, maybe I wouldn't have misspelled "losing" not once but twice and not noticed until after the edit window. <_<

Was it necessary to post this?

FYI many input methods (including my own) turn two hyphens into an em dash. The em-dash-means-LLM thing is bogus.

Ms word does this by default

You can't possibly think that using an em dash is exclusive to AI-generated output.
