Just look around you — at the people crouched over their phones as they walk the streets, or drive their cars, or walk their dogs, or play with their children. Observe yourself in line for coffee, or in a quick work break, or driving, or even just going to the bathroom. Visit an airport and see the sea of craned necks and dead eyes. We have gone from looking up and around to constantly looking down.
