Yes. It doubles Chinese or Spanish. But again, we are in 2016. As a civilization we have a global communication system. But we can not understand each other.

We are 7 billion people. 200 million speak english as a secondary language and 300/400 million as main language. With this numbers, don't you think that it will be better to find a language that is fine for everybody? Or when someone wants get into the international arena he/she must to learn English which will take years?
