For that matter, there's probably a human tendency to oversimplify most things.

I agree with this, definitely.

Have you read Everything Bad Is Good For You by Steven Johnson? It's referenced in the article. He takes the premise that video games, television, and movies are maturing as artistic forms, getting more complex, and end up actually being good for our brains rather than rotting them. There is (surprise!) some over-simplication, but overall I think it holds up, and I recommend it.
