I'm really sad about this, because I'm a word (and punctuation) nerd and use em-dashes in my own writing, because they're correct, dagnabit. Now I'm reconsidering the practice.

This may cause some psychic damage, but I use en dashes instead for this reason... even though yes, it's only conventionally used for numeric ranges.

Keep using them. Don't let AI steal beautiful em-dashes away from you.

LLMs don't put spaces around their em-dashes.

I had to take a look for myself and damn... It's almost as if this was done intentionally to be ironic or something.
