Wilford, J.N. (2007). Languages die, but not their last words. New York Times. September 19, 2007. Available online: http://www.nytimes.com/2007/09/19/science/19language.html?hp.
While focusing on antiquarian relics, the article points to good news: globalization is reducing the number of widely spoken languages.
Languages are not unique creatures with rights of their own, but tools used by people to know the world, provide for their families, and live life. The power of languages — like the power of most platforms — is proportional to the number of people who speak it. When a language’s speakers abandon their traditional tongue and embrace a more popular method of communication — like the rise of German over Low German or Mandarin over Manchu — both peoples benefit.
