The Almighty English. The rise or the fall?

Between the splendid reigns of Queen Elizabeth the first and the second, the number of English speakers escalated to innumerable figures. The mother tongue speakers however,contribute a mediocre percentage. People who speak English as second or foreign language are a lot according to fundamental statistics.Now, what accounts for the lamina of these increases. Social networks. Yep, that's right. Together with the modern desire to communicate at a world level over long distances. But what's fascinating is that these so called pull factors are actually reconstructing the English language, it's usage and it's governing rules.So the million dollar question is: What's going to happen to the beloved language in the future? Most likely today's teens won't care less about grammar, I mean these kids are already substituting words with numbers e.g C U L8er.And quite frankly, they don't seem to be bothered with achieve a certain level of fluency let alone enriching their vocabulary.Only handful of them are aware that the word dude has its ancestry in German, and that dude means idiot but still they toss the word around nonchalantly. Don't even get me started with improper use of words like "Like" "Hectic" "Hardcore" . What does the future hold for the main language of books, magazines and the internet? While it adapt and survive?Will it transmute into new languages?
