No phones, no internet at school. If you can't bring enough material into the building within books and teacher's brains to teach, you're terrible and pointless. Leave the screens to their software and programming classes.
I'd say it will be a blessing when this debacle is replaced with AI, except the AI will also come from the revolving income stream guys, and will also have children's well-being as an afterthought. It will be the same failure, but with 4x the margin going to 1/100 the previous number of vendors, just like every "tech advance" in the past decade.
