According to researchers, English as it is spoken today will have disappeared in 100 years and could be replaced by a global language called 'Panglish' (the article doesn't explain the name further).
"New words will form and meanings will change with the most dramatic changes being made by people learning English as a second language. The global form of English is already becoming a loose grouping of local dialects and English-based common languages used by non-native speakers to communicate. By 2020 there may be two billion people speaking English, of whom only 300 million will be native speakers. At that point English, Spanish, Hindi, Urdu and Arabic will have an equal number of native speakers."
