If I understand correctly you are proposing to cut the teaching staff in the typical schools in the US to 10%, this 10% are there to place the students in front of the ai that makes the kids smarter?
I was thinking not even that. I was thinking just a dedicated staff of proctors to ensure no cheating during exams. Along with that, we can introduce psychologists for social/psychological support. But yes, the K-12 teachers as we know them need to go as they are wildly inadequate given the current state of technology.
