Do you think that a universal language will emerge within the next century? English is   51  the lingua franca in many parts of the world, and is the best language currently to know   52  business and science,   53  I don’t think English will   54  become a universal language. I think that if a language becomes the world language, it should be an artificial one.   55 , it might seem to many as an effort to   56  a certain cultural group. The   57  with a universal language is how to   58  it, and how to get the governments of the world to agree   59  its implementation.

If this were to happen, the international language would be the   60  second language of all countries, and legally it would still play second fiddle to the current language of that country. It could allow different tribes in Africa to communicate, or   61  communication between small villages in India that each speaks different languages. Not to   62  it would mean that one would only have to learn two languages no matter   63  in the world he travels.

What   64  specifics—what writing   65  should it use? Where should its words come from? Should the language be highly inflected or very analytical? And furthermore, how will the language be established?
