Every time I see the em-dash call out on here I get defensive because I’ve been writing like that forever! Where do people think that came from anyway? It’s obviously massively represented in the training data!
Where's the emdash key on your keyboard? There isn't one? Oh, maybe that's why people who didn't already know or care about emdashes are very alert to their presence. If you have to do something very exotic with keypresses or copypaste from a tool or build your own macro to get something like an emdash, or , it's going to stand out, even if it's an integral part of standard operating systems.

Mac, alt-minus. Did by accident once, causing confusion because Xcode uses monospace font where -, – and — look identical, and an m-dash where a minus should be gets a compiler error.
iOS, long-press on the "-" key.
