What's sad to me is that so many languages were just fine 100 years ago. World Wars, state action (in both totalitarian and democratic states), mass media, and globalization are eradicating most of the world's linguistic diversity. As a kid, I assumed languages, ethnicities, and states were almost synonymous. States would certainly want you think that! In the present, I can see how much damage the concept of the ethnostate has done to minority languages in any given territory. At this point, we've already suffered irreversible loss, and a lot more is already baked in.
