We are becoming increasingly dependent on computers. They are used in
businesses, hospitals, crime detection and even to fly planes.
What things will they be used for in the future? Is this dependence on
computers a good thing or should we he more auspicious of their benefits?
Model Answer:
Computers are a relatively new invention. The first computers were built
fifty years ago and it is only in the last thirty or so years that their
influence has affected our everyday life. Personal computers were introduced as
recently as the early eighties. In this short time they have made a tremendous
impact on our lives. We are now so dependent on computers that it is hard to
imagine what things would be like today without them. You have only got to go
into a bank when their main computer is broken to appreciate the chaos that
would occur if computers were suddenly removed world-wide.
In the future computers will be used to create bigger and even more
sophisticated computers. The prospects for this are quite alarming. They will be
so complex that no individual could hope to understand how they work. They will
bring a lot of benefits but they will also increase the potential for
unimaginable chaos. They will, for example, be able to fly planes and they will
be able to co ordinate the movements of several planes in the vicinity of an
airport. Providing all the computers are working correctly nothing can go wrong.
If one small program fails disaster.
There is a certain inevitability that technology will progress and become
increasingly complex. We should, however, ensure that we are still in a position
where we are able to control technology. It will be all too easy to suddenly
discover that technology is controlling us. By then it might be too late I
believe that it is very important to be suspicious of the benefits that
computers will bring and to make sure that we never become totally dependent on
a completely technological world.
