Men,though the ages, has undergone many changes from the time when he depicted a herd a mammoths on the walls of his cave to these days. When he can create beautiful picture and even make coffee by use of computer technology without leaving his favorite chair. The 20th century made huge step in developing computer technologies and reach many goal that make our life easier. What should we expect in the 21st century

First of all, I think that the pace of our life will speed up.we will move faster from one place to another place.From one continent to another continent by using high speed jet airplanes.
Second of all,I believe that we will be able to do many things that take much time now without leaving our house.Computer will be everywhere including out clothes.Many people will have chips and mini computer inserted in their heads to hold huge amount information and have a quick access to it.

But what will be the most amazing things in the 21st century,is the flight to the outer space and mars that will be available to all people.scientists says that mars has many things similar to the Earth's.Moreover, they say that with the help of modern technology people can artificially create conditions that will allow people to live there on the constant basis.
To sum up , i am sure that many amazing changes will be brought by the 21st century. Furthermore,I think that with the help of contemporary technologies people can do many things that were even difficult to imagine a century ago.So nowadays it is rather difficult and even impossible to imagine all changes that will happen in the next decades.
