Computer instead of translator

The modern world is the world of technologies and science. They make their contribution into the development of all spheres of life. So, special computer programs were created to make the translation from one language into another. It seems to be the miracle, but at the same time interpreters understand that if computer technologies develop rapidly society won't need this profession at all in few years.
Nowadays interpreters have nothing to worry about, as mechanical translation has a lot of mistakes and confusions in the translated text. The lexical analysis of the texts showed that the majority of computer programmes translate only parts of speech properly, but it makes a lot of mistakes when it translates tokens, complicated sentences, and different forms of parts of speeches.
Another serious problem is the lack of accuracy during the translation of polysemantic words. This is the serious problem for interpreters not to mention computer programs. This problem together with translation of proverbs, pan, and jokes are often confused by people not to mention computer programs.
