This is a most excellent place for technology news and articles.
So where exactly are kids supposed to go? People will go on about "they should just go outside" but kids have literally had the cops called on them for the crime of walking around their own neighborhood "unsupervised". I've seen calls to ban kids from all sorts of places - planes, theme parks, restaurants, libraries. I've seen these "mosquito" things put up to drive kids away from public places. Kids are spending all their time on social media because they have nowhere else to go.
Even excluding everything other than computers, you can still play games, talk to friends, code etc.
