My kids get very limited screen time, and are expected to fill their life with art and activity that does not involve, at least not directly, cheap electrons. Expected, because its what we, their parents do by way of example.
And I'm damn proud of my kids now. They're the ones pointing out how their high-school is taken over by mobile-phone-zombies, utterly un-interesting and useless peers.
So, yeah. Its an epidemic. Kids don't need technology. It has been so for thousands of years, and I truly believe in an event horizon where there are limits to how involved in 'the next great thing' kids should be allowed be, and to engage.
I'm all for using computers productively. I'm not cool with 20 kids standing at the train station not talking to each other, not standing on the right side of the yellow line, not paying attention to the train that is about to push them off the platform, just so they can push a few pixels around. This is junkie dystopia, people.
