I like history very much and I just wondered about this question. History constantly repeats itself: powers rise and fall, then an other power does so. Look at the Greeks, e.g! What a sophisticated culture they had, how strong they were, and now there are only a few millions of them and nobody really cares about them in world politics. The same applies to the Roman Empire. Once both Latin and Greek used to be lingua francas, nowadays only very very few people speak it as a second language. Will the same happen to the English language as well in the course of time?
