California just got strict about this, too. I have found a dramatic increase in the amount of interpersonal talking that's happening in school as a result, which is great!

Australia banned phones in schools 1-2 years ago and it's been widely recognised as a huge success. I think banning social media like facebook/tiktok/etc for kids would be a huge benefit as well. Leaving just IM/group chats for kids to directly talk to each other without scrolling a feed of ragebait and ai slop.
