Which language will take over our future?

I believe when you finished reading the title, the initial answer was “English”. And I agree with that, I personally don’t believe any other language is able to flip it over in this century. Since we already read relative articles and discussed about the dominance of English in class, I would like to dig a little deeper into it and take a closer look at the possibilities of whether one another major language will take it over. 

      

First of all, which language is the most possible one? One thing I’ve noticed is the list of languages in terms of using population on the Wikipedia and Baidu. Chinese, without doubt, has the most native speakers, Spanish second with English third. But as we learnt from the reading by David Crystal, the world language is not determined by how much native speaker a language has, but how many none-native people is learning and using it as a second, third or fourth language. And I totally agree with his opinion. So let’s take a look of why Chinese has the most native speakers: China has almost 1.5 billion population, about 45 times of the United States, which takes up almost 19% of the world population. So it’s not hard to figure out why Chinese is on top of the list instead of English. 
Then how about Chinese’s rank on the list of none-native speaker amount? Only No.4, and this time, English, the current world language took the first place with a remarkable advantage. With the development of China, it indeed plays a bigger part in the world with its own language, Chinese. I’ve heard some interesting comments in China that some people think Chinese may have a chance to be the world language in next a few decades or later this century. 
In fact, I would like to think the dominance of English is unprecedented consolidated. For example, as a aviation interests, my biggest childhood dream was become a civil aviation pilot, so I’ve worked a lot on it. The only language every airport should have in their broadcast and radio is English, for international airports, English is required in public channel, so that every airliner from every corner of the world can understand properly to avoid conflicts. That’s how “Air Speak” works. At least I don’t think Chinese do have a chance if there’s no major world power alternation, but your thoughts? Do you think Chinese, or an another major language like French have a chance to end up English and become truly worldwide in 21st century? But I can tell you this, Chinese is as hard as it looks like, you guys don’t want to learn it just because you have to.
