[EDIT] Several commenters rightly noted that heavy em-dash usage is normal for the New Yorker (and common thanks to OS auto-replacement), so my “LLM giveaway” quip was off-base. Leaving this up for context—thanks for the corrections.
I had to stop using em dashes in my own writing because it triggers people who never really thought about them prior to reading about their association with LLMs.
I’m convinced most folks noticing this now just weren’t aware of the punctuation before they heard about it in the AI paranoia context.
I’m also convinced a good chunk of Reddit comments are AI spam. But, I mean, we have to imagine anyone running an AI campaign knows to avoid the em-dashes by now.
So it’s just as likely that by spotting those features in a post you’ve found an Apple user as it is that the poster is an LLM.
