Is there anything actually bad with that writing (other than implying that theirs is the first system to solve this)?

AI has been rlhf post-trained to generate text that people find to be clear to read. Are you now looking to reject clear writing just to spite AI labs?

Pieces of writing don’t really exist in isolation. Your opinion of a given chunk is formed not only by it, but by everything else you have read.

So in one part the negative reaction is to staleness. Everything sounds the same.

If it was all the same but dry, terse, and to the point (like technical writing), it wouldn’t be so bad.

But it’s repetitive with an annoying, breathless, get-ready-to-be-impressed voice that many of us find grating.
