It's possible that the goal of the course is not to be able to produce an A paper but to gain the knowledge that would allow one to produce an A paper. That is to say, the paper may be a measurement not the goal.
If the AI provides the knowledge, and you have the AI, you have the knowledge.
And as Goodhart explains, that makes it a bad measurement. Invent better measurements that measure the actual goal.
Learning? For humans? Visionary.
Learn all you want. Why do you need a grade to tell you what you learned? Why do you need an employer to require you to prove you memorized a book?
