"The other major trend is the collapse of cultural diversity that has come about as we have sort of drifted from a polychromatic world to a more monochromatic world, I would say, of monotony. And the great indicator of that, of course, is language loss. When you were born, there were six thousand languages spoken around the planet. And a language isn't just a body of vocabulary, it's the soul of the people. Every language is like an old growth forest to the mind. And of those six thousand languages fully half, as we sit here, are not being taught to school children. So that means effectively, unless something changes, they're dead. That means literally, by definition, half of humanities legacy is disappearing in a generation or two. Now that's an amazing thing. Every two weeks, on average, some elder goes to the grave and carries with them the last syllables of a language."
