English is becoming the main common language but will not take over completely. Other nationalities make an effort to maintain their own language and value it more dearly, particulalry those un the UK with Engish as a second languge. For them English is merely a tool enabling them to access financial security through education and work. For socialising/family/news media/TV/movies/current affairs, its all done in their mother tongue with a few English/ameericanisms thrown in. Second generation immigrants have something few 'English' people have - access to fluency in other languages enabling them to have the best of both worlds. By building a wider skills set, they use their bilingual abilities to create internet sites, make movies, do business in other select languages - those with only one language will certainly lose out in the future. No time to be smug, learn another language, quick!
