Linguistic Deiversity

Why has English got the status as the global medium language? Because of the same reason, Windows,Microsoft  subdued  OS system in the PC world.
 Almost people feel tough to learn foreign language, and if one take a minor language as a first foreign language, he might repent it, and be bewildered to say"The arduous lesson to master language which is used for few people, was only waste of effort"Of course, It was the reason for many people to select English as the first foreign language.
  local languages will disappear sooner or later, and several global languages will prosper. Spanish, Chinese will still remain global language except for English. This three languages can be told as a language imperialism.
  German might be difficult to survive. German was only dialect,and German nobles spoke French before Goethe's Era. German language has accompanied with Nationalism. German can master English much easier than other language speakers. But, on the other hand,English speaker feel always tough to learn German, and Many German use not German but English so often abroad.
 Moreover, Many German singers sing their songs in English as much as"Schlager(Hits)" sung in German. Many people might think "It is convenient to dispense with German language."
 Japanese will survive absolutely. Because Japanese can't master English so easy and English speaker can't do Japanese alike too. Not to be intelligible may be advantageous in survival of languages.
