I'm here to learn what other people think, so I'm in favor of not seeing AI comments here.
That said, I've also grown exceedingly tired of everyone saying, "I see an em dash, therefore that comment must have come from AI!"
I happen to like em dashes. They're easy to type on macOS, and they're useful in helping me express what I'm thinking—even if I might be using them incorrectly.
I have actually been using em dashes more mainly because of everyone whinging about them.
