>sounds like your objections are over data governance?

Primarily, yes. Teachers don't need the kind of oversight they employ, and any reasons for that are purely financial, not "to make sure they aren't distracted".

>still have public school eating up 6-8 hours of your kid's time per day.

Yes. And many parents call that a feature. We structured school times around when parents are expected to work.

It's hard to cut those hours without cutting worker hours or otherwise structuring schools to have longer recess periods. I'm fine with either, but AI doesn't really come into play there.

>so you can spend the rest of the time on whatever your kid's interested in.

And who's watching them? Works fine with one stay at home parent. Or even a private tutor being there in person. Not so much with a remote education.

I'm not against more free time. But this addresses none of the bigger reasons this hasn't been experimented with seriously.
