I don’t think I’m judging shallowly- there is no em-dash on a standard keyboard. The one way it ends up in real writing is if you use a typesetting program like LaTeX, or Word changes an en-dash with auto formatting, or the user consciously interrupts their writing flow to insert the character with a special keystroke combination or by pasting it in. The proportion of people who do any of those things in writing for the web is quite small. The number of clearly AI written posts with em-dashes is quite large. So large, that I immediately suspect AI writing when I see an em-dash and I rarely see countering evidence that suggests the author is human but meticulous about how they write.

No, you are writing for people who see LLM-signals and read on anyway.

Not sure that that's a win for you.
