The question points in the future and so I see the problem of having evidence but an educated guess or quotations of linguists would do, I guess.
It is no secret any longer, though some nationalist Turks I know, passionate advocates of the Sun Language Theory, see it differently, languages have changed through time. Not quiet randomly, but by rules which historical linguists have discovered.
However, times are different know : We ve have Jackie Chan, Star Wars, oppressive governments, prescriptive language advocates, the Kings James Bible, constitutions, TV series and all the things which urges us to speak their way either for entertainment to understand what Yoda said in plain English, for our constitutional rights to know how to read the laws and thus to know how to sit on a leather chair sponsored by welfare money instead the electrical one and all other modern reasons which keep our language in a specific shape like dinosaurs eyewitnessing mosquitoes in amber.
So, what is the opinion on this the scientists came up with?
