Like many other LLM tropes they were heavily overused which attracted attention. Normal English writing doesn't average 1 em dash per 2-3 sentences like I would often see during Peak Em Dash.

They aren't a complete rarity by any means but still relatively uncommon compared to the typical punctuation one sees in routine usage.

I loved em dashes back in high school and my English teacher would have definitely returned an assignment with a lot of red marks if I used em dashes as frequently as an LLM (speaking from experience).
