Unseen Passage: Computers

Computers are capable of doing extremely complicated work in all branches of learning. They can solve the most complex mathematical problems or put thousand unrelated data in order. These machines can be put to varied uses. For instance, they can provide information on the best way to prevent traffic accidents.

They work accurately and at high speed. 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 future, automation may enable human beings to enjoy more leisure than they do today.

The coming of automation is bound to have important social consequences. Some years 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 performances, they need detailed instructions from human beings to be able to operate. They can never lead independent lives or rule the world by taking decisions of their own.

Sir Leon said that in future, computers would be developed which would be small enough to be carried in one’s pocket. Ordinary people would then be able to use them to obtain valuable information. Computers could be plugged into a wireless network and can be used like radios. For instance, people going on holiday, could be informed about weather conditions. Car drivers can be given an alternative route, when there is a traffic jam. 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 due to our failure to understand each other. Computers will also be used in ordinary public hospitals. By providing a machine with a patient’s system, 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 great many facts which will help them in their work. Bookkeepers and accountants too could be relieved of dull clerical work. For the tedious task of compiling, and checking lists or figures could be done entirely by machines. Computers are the most efficient servant man has ever had and there is no limit to the way they can be used to improve our lives.
