The emdash is a dead giveaway, but its mostly the high school level writing style.

It is astonishingly uncreative and simplistic with sentence structure, it just directly regurgitates the points from its prompt it was specifically directed to address, there's no clever or compelling phrasing or larger metaphor, there's no personality or expressiveness, willingness to say something maybe a bit edgy or controversial, very neutered and bland writing style... and there's no consecutive introduction of, then expanding on or synthesis of concepts, which are continually used after being explained and synthesized, progressively... instead, all the references are just mentioned, explained, addressed, discarded, onto the next one, like so many bullet points that need to be fluffed up to hit a word count.

Finally... did you intentionally prompt it to emulate the 'in this essay i will...' 'self contained, non referential body paragraphs' 'in conclusion, here's a few sentences that could have been the entire essay' ... did you intetionally tell it to mimic this extremely basic writing style?

Or did it just... do all of that on its own, like the mean average of five million highschool sophomore book reports?
