Well, for those that spends hours and hours playing games or on the computer or texting instead of actually spending face to face social time, they, in a way are stupid. There's a Macleans article that does a much better job talking about this and I think it's called Dumbed Down.
Anyway, the article talks about how kids that spend lots of time in technology and spend less time with people are not allowing their frontal (pretty sure it's that one) lobes in their brain to develope properly. This in turn makes it difficult for them to read body language or hold decent conversations. However, as it was mentioned previously, these people become very technologically smart and can multitask in different things and sometimes find it very difficult to only do one thing at a time.
Then again, you have to look at what it means to be smart in todays world. When you look back fifty or more years ago, "smart" was to see how much information could you stuff into your head. Were as, today, it is to see how and where you can find the information. For example. Way back then, there were things you just had to know by heart you multiplication tables. Where as today, a calculator works fine. The same idea applies to history. Then, you studied to see how many facts you can learn. Today, you study to learn the concepts, not necessarily the facts.
A friend of mine who has been on the Escapist for a few years now told me about a poll tha was done on introverts and extroverts. People that spend lots on time plugged into techonology are more likely to be introverts and want to spend less time with people then those who do not spend a crazy amount of time involved in technology. I'm an extrovert, but all of my friends are all gamers and they are all introverts. Hmmm.... wonder why that could be.....
There is a positive and a negative to these coming generations. It all depends on whether or not you agree with what those are. We have the power to alter it slightly so not so many people are socially inept, but most people don't want to pull away from technology and face the person on the other side.
