We already live in a multiverse

In a sense, we already live in a sort of visible multi-universe. I'm talking here about the cell phones, video games, iPods, iPhones, iPads, iWhatevers that are being used by half of the people in a room or on a bus. This generation is a small-screen generation—half the time they are looking at a small screen of some sort. Their presence is fragmented—instead of everyone in one place being in that one place, each person is only half-there; the other half of them is somewhere else—in a conversation with someone tens or hundreds of miles away, or in the information-space of the web, or in the artificially created world of a game.

And I'm not sure that being fragmented for most of your life is a good thing.
