Also one comment on the above video, which I just watched.

He focuses a lot on kids - which is fine. But in my experience, adults can have JUST as bad a time as kids, in terms of being locked to the screen, not being able to socialize, have a conversation.

So I think his solution - have parents band together to not give a phone to kids until a certain age - is fine, but too limited. There really has got to be better, easier ways to dramatically reduce the amount of time that people are glued to screens.
