The author goes into delightful depth about the history of addiction, but then implies at the end ("things that take mor brain time win") that after all that we haven't evolved any defenses against it.

But there are checks and balances against addiction in our culture. Your friends start to get concerned. You lose your job and can't pay your WoW bill anymore.

And these events afford us a time for reflection. I specifically don't do World of Warcraft (or amphetamines) because I know they're good at capturing my "brain time". My fear is bad for WoW's growth.

I do agree Internet addiction is a public health crisis. But I don't think we're as powerless to take it on, both individually an collectively, as the author implies.
