Motherboard says The Internet Is Killing Most Languages:

The great flat, globalized world of the internet operates pretty much as a monoculture, Kornai says. Only about 250 languages can be called well-established online, and another 140 are borderline. Of the 7,000 languages still alive, perhaps 2,500 will survive, in the classical sense, for another century, and many fewer will make it on to the internet.

Globalization of the world and the web could lead to homogenization of the languages in both places.

The adage “If it’s not on the web, it does not exist,” neatly encapsulates the loss of prestige. And as a generation of digital natives comes up, their online tongue is likely not to be their mother tongue—a loss of competence.
