Outdoor distractions are arguably more purposeful, teaching coordination, balance, navigation, all that stuff.
The two things that bother me about the half-generation or so below me (and probably lots of my peers who I just failed to notice, if I'm honest) are (i) the excessively social side to it, the constant need to be in touch, the complete inability to amuse oneself or develop a personal sense of security, and (ii) the completely artificial nature of most of the amusements, that teach absolutely nothing about the real world. And yes, I know I'm sitting here moaning on the internet, but at least it's on a site for people who are, by-and-large, interested in doing and achieving stuff ..
Let our kids be dreamers, but only after they've done the chores, completed their homework, had dinner, and it's not past 9:00PM.
It's probably possible to overdo this, but letting kids understand (and share in) the basic skills involved in running a household and surviving life as an adult are important. School and homework I'm less sure about - a strongly academic education is a pretty abstract experience (and a weak one is kind of pointless), difficult for kids to connect to real life unless their parents were engineers or particularly practically minded. Personally, I think we should probably teach kids to read, write and add-up, and then get them out into the workplace very young (14?), alongside their parents, and their parents' friends, and their friends' parents, and given them some real world experience, although it would have to be at a pretty menial level. Then when they're 18 or 20 and have some idea of what might interest them, they'd be much more motivated to study .. Of course, this would mean a rather drastic overhaul of pretty much the entire structure of our society - but I'm not sure that would be a bad thing.
