You know what, I'm gonna say that in a roundabout way, us gamers have an advantage against this problem.
Let me try to explain. Some of the more immersing games are filled to the brim with references to real life culture, from science and history to religion. Right? I mean, personally, I've been compelled to look up something I saw in a video game on more than one occasion. Sometimes I'd learn that a seemingly made up name or term was already established in English vocabulary, sometimes I'd find a reference to a piece of already written literature, or even learn a scientific process I wasn't familiar with before. Hell, Psychochef's example regarding Khrushchev had me thinking of Snake Eater.
Maybe I'm going too far into the "games are art" mentality, but I think there's some merit to it. I'm not so foolish as to say that video games can replace education, obviously, but I think that the really good ones can encourage a youngster to learn a little bit more than he/she'd originally care about.
Anyway, I think the point Mister Bauerlein drove best was that these days, teenagers can hide in their teen "bubble" more easily than ever, thanks to their savvy gadgets and online communities. It just gets harder and harder to "grow up." And that's really the heart of the problem, isn't it?
