I applaud your efforts and very much appreciate your candor. I would love to read your piece, if you have a link or .pdf files you can dropbox for MacRumors members to read.
However, I think you are making a few assumptions about first, my niece and second, about this generation. For a one and a half year old, my niece is learning to recognize images, sound recognition and other cognitive skills with a variety of tools. It's amazing how she is able to pick up on things so quickly. It not only builds her communication skills but also promotes learning within other areas. Now, if we were to just toss the iPad at her and say "have at it"--that would be a travesty. However, family members are constantly interacting with her while viewing these shows, pointing out words, shapes--you know, the basics. Either that, or she's listening to music in the car and gauging a sense of rhythm and time. Storybooks are constantly read to her on a nightly basis. Other days she's running around the yard, exploring nature, just like we did during the 90s (my generation) and what sounds to be like your generation as well. I do support variation and interaction during child rearing rather than plopping them in front of the television.
I think the "kids" you are talking about are tweens and teenagers who are too absorbed in their social media lives and textual lives to embrace the outside world. Same goes for adults too. It promotes a sense of security. If someone refuses to make eye contact, they can't draw the attention of a potential attacker or violator. It's a society of (fear, consumerism, capitalism) or whatever private school liberal arts argument you want to use.
Nintendo DS, PSPs, Blackberrys, iPhones, iPads, Xooms, whatever the device may be is part of escapist society. People can create their own little bubble by absorbing themselves in a world unlike their own. Usage of devices on public transportation does decrease social interaction, but people have a choice to put said device away. The fact that they don't, has deeper implications than "technology."
Technology has served the populous very well--and I'm sure you don't dispute that fact. The pathways it has opened up for individuals with disabilities is remarkable. I don't think you're trying to make the technology is the root of all evil argument--so please don't interpret it as that but perhaps that it makes us anti-social. Sure. But I think there are more paramount issues at stake than technology in the adult world for the anti-social/lack of eye contact. And of course that trend is going to trickle down to teenagers and tweens.
I apologize for continuing to make this thread off topic.
