For what it’s worth, gptzero.me rates it as entirely AI generated, with 100% confidence. It’s not perfect, but it’s a pretty strong signal.

Certain aspects of how it’s structured and written do also seem AI-generated—for instance, the simultaneously persuasive but explanatorily equivocal tone is pretty typical of current LLMs. Also, there are just some text formatting features that are pretty rare for humans to use—for instance, using the nice-looking Unicode 1/2 fraction glyph, which isn’t really in keeping with the otherwise unpolished maths formatting.

It’s a bit sad that AI writing is now so good as to seem almost authentic, if not for the giveaway of a few subtle stylistic quirks.
