This is what schools enforce, second, even more important part is what parents do/allow/pay for at home.

Every single household I've seen benevolent use of phones/tablets/tv/computer/consoles (quite often all of it), kids were unruly, had shitty grades, living empty lives without good role models and very little passions or hobbies, and overall were more depressed than happy.

I do get why - its supremely easier to just throw tech at them and let them drown in endless cheap dopamine content, triple that for already-addicted parents. The whole principle of active screen itself is so overpowering and addictive compared to good old physical toys, drawing, paint, reading etc.

As a parent of young kids, its much harder to come up, continuously, with good motivating program out there, or even indoors, ie climbing. But - I didn't get kids to have easiest possible life, coursing through our short lives deep in comfort zone is a failure IMHO, thats not life well lived, that's life avoided. I am not kind to such parents - its the biggest achievement, or failure, in one's life, biggest challenges bring biggest rewards. Rather few people put in corresponding effort continuously, compared to careers, relaxing and other aspects of adult lives.

And then folks wonder why so many old people are sour, seeing in more life-successful others all the stuff one could/should have done if not so lazy is deeply depressing, usually amounts to biggest life regrets.
