I think we have just worked out why though D.
On another thread, when asked to summarise an article that the thread was started supposedly to discuss, BeeS's answer was that the poster should ask AI to do it.
I suspect that some posters rely on AI to disseminate articles and papers and go with that, rather than spending the effort to gain greater understanding through reading it, evaluating it and checking the conclusions personally reached. It explains a great deal, doesn't it?
