TIL that apparently AI is well known for using the em dash, and that a lot of use of the em dash is a way to identify AI-generated work.
Uhh... I use the em dash. I was taught to do it in writing classes where the instructors said that anything within parentheses is skipped by a reader, so you put something inside the em dash instead.
It seems that spelling and grammar are in such sort supply in our society that people assume that anything well-written isn't being done by a human.
So now, my attention to spelling and grammar will increasingly make people think that my own human-written content comes from generative AI.
