For good or bad, computers are now part of our daily life. With the price of a small home computer now as low as $50, experts predict that before long all schools and businesses and most families in the richer parts of the world will own a computer of some kind. Among general public, computers arouse strong feelings. People either love them or hate them.
The computer-lovers talk about how useful computer can be in business, in education and in the home. Apart from all games, you can do on them, your accounts on them, learns languages from them, write letters on them and in some places even do your shopping with them. Computers, they say will also bring more leisure, as more and more unpleasant jobs are taken over by computerized robots
The latter, on the other hand, argue that computers bring not leisure but unemployment. They worry, too that people who spend all the time talking to computers will forget how to talk to each other. Their biggest fear is that computers may eventually take over from human being altogether
