Excellent article. I've known people who became obsessed with sport. I'm talking 40+ hours of drill and prep for Football, spending thousands on equipment the whole run. You never see articles freaking out about this behavior.
Video games are the new threat to traditional media. You and I have shared articles back and forth about the Book Panic of the 1850's, the Radio panic of the 1920's the Comic Book Panic, etc etc etc.

Having a kid with an obsession about something, whether it be space, heavy machinery, sports, science, etc can be a good thing if you have good parents that temper that obsession with healthy social and mental development. Then direct that energy at a career that the kid can excel at.
