As someone who spends much of the day staring at screens (more macbook than phone) I'm not sure that's going to happen in a hurry. I guess it's hard to distinguish the mindless staring from learning something useful. I can't even figure which category my own time reading the latest Trump craziness falls into though probably more the mindless category.
