【简答题】
For Conversation Press # 1 I’ve got a cell phone, e-mail and voice mail. But why am I so lonely? A funny thing happened on the way to the communications revolution: we stopped talking to one another. I was walking in the park with a friend recently, and his cell phone rang, interrupting our conversation. There they were, talking and talking on a beautifully sunny day and I became invisible, absent from the conversation. The park was filled with people talking on their cell phones. They were passing other people without looking at them, saying hello, noticing their babies or stopping to pet their puppies. Evidently, the cordless electronic voice is preferable to human contact. The telephone used to connect you to the absent. Now it makes people sitting next to you feel absent. Recently I was in a car with three friends. The driver hushed the rest of us because he could not hear the person on the other end of his cell phone. There we were, four friends zooming down the highway, unable to talk to one another because of a gadget designed to make communication easier. Why is it that the more connected we get, the more disconnected I feel? Every advance in communications technology is a setback to the intimacy of human interaction. With e-mail and instant messaging over the Internet, we can now communicate without seeing or talking to one another. With voice mail, you can conduct entire conversations without ever reaching anyone. If my mom has a question, I just leave the answer on her machine. As almost every conceivable contact between human beings gets automated, the alienation index goes up. You can’t even call a person to get the phone number of another person any more. Directory assistance is almost always fully automated. Pumping gas at the station? Why say good morning to the attendant when you can swipe your credit card at the pump and save yourself the bother of human contact? Making a deposit at the bank? Why talk to a clerk who might live in the neighborhood when you can just insert your card into the ATM? I am no Luddite. I own a cell phone, an ATM card, a voice mail system, an email account. Giving them up isn’t an option — they are great for what they are intended to do. It’s their unintended consequences that make me cringe.
