I just learnt the difference, an em-dash is as long as an m and used for other things than the shorter en-dash (as long as an n).

Em-dashes are more common in literature, which a lot of AI is trained on, rather than online speak where it’s annoying and difficult to notice the difference between - and — (and not to be confused with –).

And yet, plenty of memes to be had, shared, created, evolved and enjoyed.

Seems a skill issue?

Same for unregulated systems, only without transparency, limits or recourse
