> It drives me crazy that em-dashes are supposedly a smell for AI now.

They're an excellent tell for comments written on places like HN, Reddit, and other forms of social media. The average person (myself included) simply does not write very well and I would wager the majority of English speakers are not able to properly use an em-dash.

I expect them in books and suspect that's where the AI models are getting them from, but those are being written largely by professionals.

It's at a point where the moment I see an em-dash on a social media post I cease reading it and move on to the next.
