AI output right now is like a final exam essay response from an anxious student. Instead of being edited for focus and clarity, it's anti-edited to cram in as many details as possible. Instead of worrying that the reader might get bored or confused, it assumes that the reader has no choice but to read the whole thing, even if they get a headache. It doesn't care about picking the most useful perspective on a problem; it cares about covering every possible angle that a grader might use to dock points from it.

It's basically the work you get from a smart, diligent person who is oblivious to any shared goal and approaches every assignment with a CYA attitude.
