..people who have been using AI to cheat through highschool/college will not suddenly study two years worth of material over the month..

Oddly enough, I know several younger people - men and women - who are no longer using AI to write up their work for school, because as they claim, the results are getting poorer. In one case the AI generated a set of conclusions that were entirely unrelated to the main point of the paper. The guy ended up backpedaling on the whole project, which he'd only started on and had to use several weekends to sort it.

Where I would use AI was to find the source materials and then verify those sources to make sure they were organic and not synthetic, then go forward on my own...

But I'm also an old fart, so what do I know of how higher-ed rolls today.
