In his speculative WSJ essay, “What the World Will Speak in 2115,” the linguist John McWhorter forecasts the future of verbal communication on Earth. Unsurprisingly, he believes it will be a flatter and less diverse world, a village increasingly global. History will need a huge interruption for this contraction, which has its pluses and minuses, to not occur. An excerpt:

“Science fiction often presents us with whole planets that speak a single language, but that fantasy seems more menacing here in real life on this planet we call home—that is, in a world where some worry that English might eradicate every other language. That humans can express themselves in several thousand languages is a delight in countless ways; few would welcome the loss of this variety.

But the existence of so many languages can also create problems: It isn’t an accident that the Bible’s tale of the Tower of Babel presents multilingualism as a divine curse meant to hinder our understanding. One might even ask: If all humans had always spoken a single language, would anyone wish we were instead separated now by thousands of different ones?

Thankfully, fears that English will become the world’s only language are premature. Few are so pessimistic as to suppose that there will not continue to be a multiplicity of nations and cultures on our planet and, along with them, various languages besides English. It is difficult, after all, to interrupt something as intimate and spontaneous as what language people speak to their children. Who truly imagines a Japan with no Japanese or a Greece with no Greek? The spread of English just means that earthlings will tend to use a local language in their own orbit and English for communication beyond.

But the days when English shared the planet with thousands of other languages are numbered. A traveler to the future, a century from now, is likely to notice two things about the language landscape of Earth. One, there will be vastly fewer languages. Two, languages will often be less complicated than they are today—especially in how they are spoken as opposed to how they are written.”
