Whatever past estimates or surveys have found, as elusive as precision is with this, it should be obvious by now, 2016, that English is not just on its way to dominate as the language most rapidly growing in usage, and dominant in ALL usage in international forums.
Sure, French dominated for awhile in the expanding WESTERN cultural spheres, Latin before that, Greek before that. Now it is English in ALL cultural spheres, and the militantly anti-Christ pagans and atheists who now rule are trying to capture the definitions into their “Newspeak”.
I made friends with a group of air traffic controllers in Medellin Colombia at an international airport there. I’m sure that all of them around the world have to speak the technical “aviation English”, but these guys said they ALL have to learn non-hyphenated FLUENT English, so that in an emergency there is a fast common understanding. They said all international PILOTS too. For example, language fluency (lack thereof) was suggested in one recent year when there was a passenger jet that crashed in New York because it ran out of fuel.
Doctors study new medical developments in English.
The foremost ESL computer hackers –good guys and bad guys too I’m sure– are admonish by their ESL peers to learn English to become good programmers for a number of reasons.
I used to despise the idea of arrogant American tourists demanding the natives speak English to them. Nowadays my wife tells me there are Cuban patients in the assisted living home who demand the workers there speak Spanish to them. (Takes all kinds. I had a Cuban boss who rebuked a co-worker for speaking Spanish to me though I’m fluent).
NOTE that I am not KJBO because the language is English, but English just happens to be in the direction where one would look for God’s best characteristics for his perfect preserved word.
The most influential persons and groups in the world among their peers are English-speakers.
Not everyone need speak it for this to matter in the which-version topic. Just as in the times of Christ, when we all know why God used Greek through his servants to spread the WRITTEN gospel throughout the world and with most effect in diverse cultures.
Who are we to tell God he cannot do the same thing for the 20th and even more so, the 21st centuries?
