This is a good statement of what I suspect many of us have found when rejecting the rewriting advice of AIs. The "pointiness" of prose gets worn away, until it doesn't say much. Everything is softened. The distinctiveness of the human voice is converted into blandness. The AI even says its preferred rephrasing is "polished" - a term which specifically means the jaggedness has been removed. But it's the jagged edges,…
I think it is also fairly similar to the kind of discourse a manager in pretty much any domain will produce. He lacks (or lost thru disuse) technical expertise on the subject, so he uses more and more fuzzy words, leaky analogies, buzzwords. This maybe why AI generated content has so much success among leaders and politicians.
Be careful of this kind of thinking, it's very satisfying but doesn't help you understand the world.
