It is a difficult question to say what will be after 50 years.As me, nobody can say what will be in our future but ,however, I will try to answer and tell you about my opposition about this qouestion.So, I think that modern means of various will be developing.And as me it will be able to reach to the most distance places for some minutes.I think that people will not be communicate with each other mainly because modern man becomes a 'robot'.But it is only my opinion and I wanna say again that no one can say what will be in future.
