Adult life begins in a child’s imagination,” said poet Dana Gioia, speaking before the graduating class of Stanford University in June 2007. “And we’ve relinquished that imagination to the marketplace.” By that, Gioia, chairman of the National Endowment for the Arts, meant that we’ve pawned off the task of imagination to commercial manufacturers of marketing and entertainment. They feed us an endless stream of stock imagery and flashy distractions—“content” that comes predigested and does little or nothing in the way of encouraging us to form our own mental images, ideas, or stories.

Gioia’s speech lamented a cultural impoverishment that he said was evident in a widespread lack of interest in the arts and artists, a situation that he blamed on the media’s preoccupation with entertainers and athletes. Indeed, some members of Stanford’s graduating class were rather unimpressed with the selection of Gioia as speaker: They didn’t think he was famous enough. Perhaps that’s because he doesn’t really show up on TV—or YouTube or MySpace or anywhere that might have given him some credibility or at least name recognition among the graduates. It’s hard for scientists, writers, painters, and thinkers to compete with the continual stream of spectacle produced by the likes of Britney Spears and David Beckham, in a market where young people spend 44.5 hours each week in front of computer, TV, and video-game screens.

Much has been discussed about whether all these hours of screen time have contributed to the explosion of ADD, aggression, autism, and obesity in children and teenagers. What I’d like to consider is what kids are not doing during those 44.5 hours of screen time (besides not reading Gioia’s poetry) and how it could haunt them in later life.
