     As civilization proceeds in the direction of technology, it passes the point of supplying all the basic

essentials of life-food, shelter, clothes and warmth. Then we are faced with a choice between using

technology to provide and fulfill needs which have now been regarded as unnecessary or, on the other

hand, using technology to reduce the number of hours of work which a man must do in order to earn a

given standard of living. In other words, we either raise our standard of living above that necessary for

comfort and happiness or we leave it at this level and work shorter hours.

     I shall take it for granted that mankind has, by that time, chosen the latter alternative. Men will be

working shorter and shorter hours in their paid employment. It follows that the housewife will also expect

to be able to have more leisure in her life without lowering her standard of living. It also follows that

human domestic servants will have completely ceased to exist. Yet the great majority of the housewives

will wish to be relieved completely from the routine operations of the home such as scrubbing the floors

or the bath of the cooker, or washing the clothes or washing up, or dusting or sweeping, or making beds.

      By far the most logical step to relieve the housewife of routine is to provide a robot which can be

trained to the requirements of a particular home and can be programmed to carry out half a dozen or

more standard operations, when switched by the housewife.
