“Riding the crest of globalization and technology, English dominates the world as no other language ever has, and some linguists now say it may never be dethroned as the king of languages”.
It is true that English does rule, however I am not sure if I agree with the quote. Tendencies right now depicts a world where the count of people with English as their first language is drastically falling. However, the number of people speaking it as their second language is raising. This leads to the fact that more and more people becomes bi-, and even multi-, lingual. It does not really make sense that English will stay as the king of languages if there is another language which more people have in common.
As mentioned before, more and more people speak two or more languages. In countries like Denmark it is not unusual that people actually speak three languages; Danish, English and German. However if you descent from another country, like Arabia or Russia, it is not uncommon to also speak that as a mother tongue. As we learn more and more languages it might not even be necessary to have a common international language.
So in conclusion, judging by how the world looks now, English is already on it’s way to dethroning, as more people speak several languages. On the other hand, it is very difficult to guess the future, and English might as well stay on the throne, just for a little while longer.
