Little boxes
In recent years there have been many predictions
about what our houses will be like in the future.
Some experts think we will all live in boxes;
others think we may actually live on the moon or
another planet! Two things are clear. We will use
power from the sun, wind or sea and computers
will control everything in our lives and especially
in our homes.
Every house will have devices to change energy
from natural sources into power, and we’ll
build houses that can use this power efficiently.
Computers will open and close doors to allow
people to come in and out and they will make
sure the house and the people in it are safe.
They will switch on the lights when we go into
different rooms or switch on gadgets when we
ask them to. They will know when the fridge is
empty and order food automatically. They will
even tell us who has visited the house while we
were out and at what times!
Rooms will be smaller than today but furniture
like beds, tables and chairs will come out of the
floors and walls when we want to use them.
Again, the computer will do this for us.
Some experts predict that computers will
control the entire world in the future, so
perhaps they might decide to shut us in our
little boxes for ever! There’s a thought.

1 We may live on the moon in the future. ___
