lol every word processor since the nineties has automatically expanded em dashes, and some of us typography nerds ­manually type em dashes with the compose key, because it's the correct character, and two hyphens does not an em dash make

The em dashes are there because they're used extensively by professional writers.

You will be foiled by a regex

Can you explain?

sed 's/—/ /g'

How so

I thought I was making a fairly obvious jokey riposte?

"If you're claiming that em dashes are your method for detecting if text is AI generated then anyone who bothers to do a search/replace on the output will get past you."

And a semicolon, AI really likes semicolons.

The em dash isn't just the present state of AI slop— it's the future!
