Are kids getting dumber thanks to TV and video games?

As someone who had hoped that Tivo and the internet were going to raise my child, I have to say that I am disappointed by this SF Gate article that says kids today are dumber than ever and may in fact be getting dumber as we go on.

As for the rest, well, the dystopian evidence seems overwhelming indeed, to the point where it might be no stretch at all to say the biggest threat facing America is perhaps not global warming, not perpetual warmongering, not garbage food or low-level radiation or way too much Lindsay Lohan, but a populace far too ignorant to know how to properly manage any of it, much less change it all for the better.

Now I feel even more pressure to make money so my kid isn't a moron. The thing that throws me is that when I grew video gamers weren't as obsessive as they are now and yet lots of kids I knew were completely stupid.
