Elon Musk: We're facing civilizational collapse.

Elon Musk: "The birth rate on Earth is so low that we're facing civilizational collapse unless the birth rate returns to a sustainable level...Population collapse is one of the biggest threats to the future of human civilization, and that is what is going on right now. Take Japan, for example. I think population is roughly 110 million, but last year if you take the number of children born times, the life expectancy, which is 85 years, is very impressive. Life expectancy, then Japan would have, I think, around 68 million people, roughly half of the current population. That does not tell the full story because you would have an upside down demographic pyramid. You already have an upside down demographic pyramid where you know, a lot of old people, very few young people and that upside down demographic pyramid is unstable."
