The new "Nofone" technology combined with the "Parenting" social network would solve most problems, except the one where governments want to spy on everyone.
I mean that's not a helpful talking point either.
Computers, smartphones and the Internet are generally good things for the world and I firmly believe everyone should want more people (including young people) to use those things. They are useful technologies for entertainment, community, education, all kinds of wonderful and positive things.
But of course young people should be taught how those things work before they are allowed to use them unsupervised. They should especially be taught that not everyone they might encounter there can be trusted, just as is the case in real life.
