That would have sadly be an improvement for the majority of teachers I've had in my life, even university classes because they were taught by a TA phd student I couldn't understand.

It sounds distopian, but AI has been a big boost to learning at least for me personally. Of course the problem is when it's wrong.

I never said that AI should replace all teachers. AI can help provide more teaching labor (more teaching capacity). Every child can have a personalized tutor in addition to human teachers.
