More generally, the problem is almost always motivation and discipline, not the availability of instruction. If you have a motivated kid, you can simply buy them some books. The problem in public schooling is that most kids are not motivated and the emphasis is on getting everyone to the finish line.

And if you want to use AI in education, I guess the big question is whether it can help the kids who have parents who work two shifts, who get pulled into youth gangs, or play games all day and don't even show up to school. Helping talented kids from well-off homes is really not that much of a challenge.
