What can we do with computers?

We can use computers to calculate.
They can calculate at a faster speed

draw things with them. In addition,
computers can do important jobs like
operating railways and flying planes
and spaceships.

Is a computer cleverer than me?

The answer is “No”. Your brain can produce new
ideas but computers cannot. However, one day
computers may be able to do a better job than
human beings. For example, they may be better
than doctors at doing their job.

What will happen to us if computers can do all our
jobs? Will we have nothing to do? Computers may change our lives, but will they make them better?
