I am not sure what is the author trying to convey with the article. I mean... isn't it a feature of languages that they evolve and change with society? I think pretty much every language today is not exactly the same that it was a couple of generations ago so why would we expect it to be what it is now in the future? Or is the complaint just that are the Americas bringing the most changes?
