For a while, I've been complaining about people who overuse the Internet. People who walk across intersections while staring at their phones. At first, only the young were afflicted. And that was fine with me. Now, however, the epidemic has spread.
My prediction is that many pubic places will begin to develop digital use policies--just as some restaurants are offering meal discounts if you agree to leave your phone in the car! In fact, that might not be a bad idea... to be in the social world without the intrusive digital distraction.
