Why is it that the more connected we get, the more disconnected we felt? Every advance in communications technology is a setback(挫折)to the intimacy of human interaction. With email and instant, messaging all over the Internet, we can now communicate without seeing or talking to one another. With voice mail, you can conduct entire conversations without ever reading anyone. If my mother has a question, I just leave the answer on her phone. As almost every contact between human beings gets automated(自动的), the more people feel they are strangers to each other. You can't even call a person to get the phone number of another person anywhere. Telephone assistance is almost always fully automated. Buying gasoline at the station? Why say good morning to the attendant when you can pay with your credit card 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 credit card into the automatic contact? Pretty soon you won't have the burden of making eye contact at the food store. Some chain stores are using a self-canner so you can check yourself out, avoiding those cold clerks who look at you and ask how you are doing.
