"There will be one thing you do today that would have been difficult or impossible twenty years ago, impossible or unimaginable forty years ago, and unimaginable or half-described in a cheap science fiction paperback sixty years ago. Look for it. When you find it, think about it for a minute. When did it arrive? Did you notice when it first surfaced into the world? In twenty years’ time, will it be present, broken, or such an irrelevance that you’ll think about it nostalgically?"
