> Students actually aren't as homogenous as you might think. And it's one of the big challenges teachers have with a classroom of 25+

True. It's well known that some % of students do well with individual tutoring. Move faster, understand things better, etc. And another part of students don't do well with that. They need other things. Maybe help from their peers in smaller groups (like 3..8 students), some after-school extra, a fix for problems back home, whatever.

But 5y olds? They need contact with peers, play, attention from humans, run around, build stuff from Lego blocks, touch grass, etc. Learning to read, "3x4=12" math etc isn't hard enough to warrant putting 5y old kids on AI tutors.
