I was the whole time trying to figure out if it was AI.

I was ambivalent about it. The way the arguments are presented don't read as much like AI.

Perhaps it was indeed just for proofreading. Although I know that MS Word turns single dashes into em-dash. Maybe they used Word when writing the thing?

It's one of the reasons I am sort of abandoning dashes when writing and using instead semicolons.
