Purely out of curiousity, I see you are using an em dash. Did you use voice transcription or something? It looks hand-typed though. I'm confused.

I just typed two single hyphens from my iOS device. One: - two: —

Edit: when I edit this comment they have been merged in the form so I speculate this is an iOS keyboard feature.

On the presumption that this isn't a joke: em dashes appear in LLM outputs because LLMs were trained on human text which included them organically. It's not as unordinary as memes suggest.
