As a parent who gave my oldest child a (very used) smartphone just before she turned 14, I would be in favor of making smartphones illegal under age 15 (or some other number, higher or lower I don't care). I'm pretty sure they're worse than cigarettes for the future of humanity.
Agreed. Teachers are seeing the massive benefits from banning phones entirely during school hours. I think once we get data from bans for certain things like social media for kids, we'll all want to get on the wave.
Everybody wants to get on the wave about how children these days are so much worse because of the new thing.
And literally as long as we have recorded human writing we have adults complaining how the children are being ruined by the new culture or new item... and I mean we have these complaints from thousands of years ago.
So be careful, you don't have to be completely wrong to still be overreaching.
