The computer is fast, and seldom makes
a mistake, while people are too slow, and full of mistakes sometimes. That is
what people often say about computers. For over a quarter of a century engineers
have been making better and better computers. Now a computer can do a lot of
everyday jobs wonderfully. It is widely used in factories, hospitals, banks and
universities. A computer can report, decide and control in almost every field.
Many computer scientists are now thinking of making the computer "think" like a
man. With the help of a person, a computer can draw pictures, write music, talk
with people, play chess, recognize voices, translate languages, and so on.
Perhaps computers will one day really think and feel. Do you think the people
will be afraid when they find that the computer is too clever to listen to and
serve the people?
