Einstein had it right. The way to teach people is to get them to want to learn.

We had this coming once a college education became a necessary credential in order to earn a living (and since then, not actually earn a living). Once it became a necessity for survival, people went to college not to learn but as an additional bureaucratic hoop.

AI cheating is only the most recent iteration in a long line of tried and true methods, including providing sexual favors for your professor, having your fraternity / sorority vouch for your character and heritage, or having wealthy parental units make a sizeable donation to your university's science department.

Once the university system survives the shock (which it might not, since civilization is mid-collapse), then academia can get back to teaching and developing knowledge for knowledge's sake, and not because it is a means to make people richer.
