We don't
know how different our future will be in the future. We can only try to imagine
it.
At
first we think about human relationship. In the year 2050, we will use
computers almost every day. We will be making new friends through the
Internet—even our husbands or wives will be met in this way. It will be much
faster and easier for us. On the other hand, our relationships with people won't
be as important as they are today—we will feel a little lonely.
Computers
will also help us in many other activities in 2050.For example, they will be
used by the children at school to make their learning easier. In addition, there
will be much more other machines which will play a similar role as computers, like
robots which will do the housework for us.
Spending
holidays will also be completely different. Traveling to other planets or to
the moon will be available for everyone. Means of transport will, of course, change,
too. We will be using solarpowered cars, which will be much more
environmentally friendly.
We
could expect that the faster technological progress would lead to a more
polluted environment. But it isn't true. We will pay more attention to
protecting the environment. And, scientists will probably find cures for many
dangerous diseases, like cancer or AIDS. Therefore, our surroundings as well as
health will be in better condition.
Although
we can't predict the exact changes which will be made in the world, we often
think about them. We worry about our and our children's future; we have
expectations, hopes as well as fears. But I think we should be rather
optimistic about our future. We should be happy and believe good things will
happen.
