LLMs are very good at convincing people they are learning, because they give answers quickly and fairly accurately. But that makes them bad teachers, not better teachers. The fact that LLMs are good problem solvers is to their detriment when it comes to teaching. We don't want to solve problems in this domain, we want to slowly trickle information and build practice so students can solve problems.

I think people conflate productivity for learning. LLMs can greatly help with productivity. But... so can hiring an employee. Well, what have you learned? Nothing, you outsourced 90% of it. You decidedly learned less than if you were less productive and did it yourself.
