Having an em dash is not "writing like AI." It's been around forever.

"The irony, of course, is that many of the people most convinced of the em dash’s inhumanity are least equipped to spot actual AI writing"

Having em dash is also does NOT show skill in the "Writing skills used to be a way to show you're paying attention to detail and making an effort."

Em dash was never attention to detail or effort. It is a way to construct sentence when you dont know how.
