I was thinking about the ubiquity of cell phones and the price of being reachable anytime, anywhere, for any reason, no matter how trivial. And then I remembered the words of William Ayrton — a professor, scientist, engineer, and Fellow of the Royal Society — about the future of telecommuniations. (Keep in mind he said this in 1897.)
There is no doubt that the day will come, maybe when you and I are forgotten, when copper wires, gutta-percha coverings, and iron sheathings will be relegated to the Museum of Antiquities. Then, when a person wants to telegraph to a friend, he knows not where, he will call an electromagnetic voice, which will be heard loud by him who has the electromagnetic ear, but will be silent to everyone else. He will call "Where are you?" and the reply will come, "I am at the bottom of the coal-mine" or "Crossing the Andes" or "In the middle of the Pacific"; or perhaps no reply will come at all, and he may then conclude that his friend is dead.
— Professor W. E. Ayrton, lecture at the Imperial Institute, 1897
I, fortunately, haven't had anyone conclude that I'm dead when I don't answer my cell. There are, of course, times when I won't answer it; I'm not, after all, Paris Hilton.
