LLMs have been better than many teachers I've had in my life. To no fault of the teachers, it's hard to compete with something that has understanding of every subject, is hooked up to the internet, and is given 1:1 time with the person learning at any time of the day, answering promptly.

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.

LLMs have enormous capacity for supporting a person who is motivated to learn and wants individualized support and instruction. That doesn’t describe all students and there’s no reason why seat time in the classroom should be used that way - students can still use an LLM to help them learn if they’re motivated to do that, but not during class.

Confidently pretends to have understanding of every subject but is frequently spectacularly wrong

Sure, classroom sizes can be a detriment to those that require more hands on instruction time. But that's not everyone and not every school suffers from overcrowding.

LLMs are also more flattering
