Its the only medium that can handle complexity. There is no medium in the history that can handle a level of complexity that we have reached today. So we can trust it to certain degree. But language is made of three basic components and they have three different functions all together. First of all it has a solid element which is grammar.
Vocabulary changes all the time.
It has a kind of artificial life of its own. The media takes language, gives it a substance or consistency reflected back on to the body and to the mind. Reshapes body and mind and establish their own system of order. And the media change the relationship between body and mind, but in a fairly reliable and observable way. So today because of media, because of the fluidity, flexibility and changing nature of media, but with some consistency, language relationship to object is reversing.
