Question

The economy in human time is the next advantage of machines

Answer 1

Machinery has harnessed the forces of nature in the service of man. Man can fly in the air; he can send messages thousands of miles away; he generates electricity from waterfalls. All this he has done with the aid of machinery. For such jobs, the use of machinery is indispensable.

Heavy and Delicate Work:

Tasks which are too heavy or too delicate for human muscles to do can be done easily by a machine. A crane can lift loads which man never can. No man can produce silk as fine and delicate as a spider’s web, but a machine can. Without the aid of machinery such jobs would not have been done.
