One of the greatest advances in modern technology has been the invention of computers. They are already widely used in industry and in universities and the time may come when it will be possible
for ordinary people to use them as well. Computers are capable of doing extremely complicated work in all branches of learning. They can solve the most complex mathematical problems or put
thousands of unrelated facts in order. These machines can be put to varied uses. For instance, they can provide information on the best way to prevent traffic accidents, or they can count the number
of times the word ‘and’ has been used in the Bible. Because they work accurately and at high speeds, they save research workers years of hard work. This whole process by which machines can be used to work for us has been called automation. In the future, automation may enable human beings to enjoy far more leisure than they do today. The coming of automation is bound to have important social consequences.
Some time ago an expert, on automation, Sir Leon Bagrit, pointed out that it was a mistake to believe that these machines could ‘think’. There is no possibility that human beings will be ‘controlled by machines’. Though computers are capable of learning from their mistakes and improving on their performance they need detailed instructions from human beings in order to be able to operate. They can never, as it were, lead independent lives, or ‘rule the world’ by making decisions of their own.
Sir Leon said that in the future, computers would be developed which would be small enough to carry in the pocket. Ordinary people would then be able to use them to obtain valuable information. Computers could be plugged into a national network and be used like radios. For instance, people going on holiday could be informed about weather conditions; car drivers could be given alternative routes when there are traffic jams. It will also be possible to make tiny translating machines. This will enable people who do not share a common language to talk to each other without any difficulty or to read foreign publications. It is impossible to assess the importance of a machine of this sort, for many international misunderstandings are caused simply through our failure to understand each other. Computers will also be used in hospitals. By providing a machine with a patient’s symptoms, a doctor will be able to diagnose the nature of his illness. Similarly, machines could be used to keep a check on a patient’s health record and bring it up to date. Doctors will therefore have immediate access to a great many facts which will help them in their work. Book-keepers and accountants, too, could be relieved of dull clerical work, for
the tedious task of compiling and checking lists of figures could be done entirely by machines. Computers are the most efficient servants man has ever had and there is no limit to the way they can be used to improve our lives.
