Yeeeep. The biggest adjustment I/my peers have had to make to address the ubiquity of students cheating using LLMs is to make them do stuff, by hand, in class. I'd be lying if I said I didn't get a guilty sort of pleasure from the expressions on certain students when I tell them to put away their laptops before the first thirty-percent-of-your-grade in-class quiz. And honestly, nearly all of them shape up after that first quiz. It's why so many profs are adopting the "you can drop your lowest-scoring quiz" policy.

Yes, it's true that once they get to a career they will be free to use LLMs as much as they want - but much like with TI-86, you can't understand any of the concepts your calculator can't solve if you don't have an understanding of the concepts it can.
