Hours spent in front of a videogame console are hours not spent riding your bike. So we need to pay attention to that. Also, videogames speed up your reactions. And that's useful. But to some extent, hair-trigger reaction times only aggravate the problem of information overload.
Fast reactions are a good short-term adaptive response to media glut.
But what is missing in an accelerated culture is not the ability to react, but the capacity to reflect. We all react. We have to. But very few people can slow down, step back, and evaluate their situation in a deep, measured, deliberate way. And videogames don't teach you to do that.
