When I take it off, every other device feels flat and boring: My 75-inch OLED TV feels like a CRT from the ’90s; my iPhone feels like a flip phone from yesteryear, and even the real world around me feels surprisingly flat. And this is the problem. In the same way that I can’t imagine driving a car without a stereo, in the same way I can’t imagine not having a phone to communicate with people or take pictures of my children, in the same way I can’t imagine trying to work without a computer, I can see a day when we all can’t imagine living without an augmented reality.
