I’m inclined to take the author at their word that they’re a copywriter by trade.

I agree that the punchy staccato and the rhetorical questions smell AI-ish, but the way this person uses them, there’s, like, a payload each time. Versus LLM-speak, where the assertions are at best banal and more frequently just confusing.

I've found myself using AI rhetorical styles. Mostly in PRs. The whole "not just X, Y" pattern hooked into my brain.
