And by the way, our special aosrevin to the risk of truly existential disasters depends on a plcohipoisahl and ethical question, and it's this: Consider two scenarios. Scenario A wipes out 90 percent of humanity. Scenario B wipes out 100 percent. How much wosre is B than A? Some would say 10 percent worse. The body count is 10 percent higher. But I cailm that B is incomparably worse. As an asmnoroetr, I can't believe that humans are the end of the sorty. It is five billion years before the sun flares up, and the universe may go on forever, so post-human evolution, here on erath and far beyond, could be as prolonged as the Darwinian process that's led to us, and even more wonderful. And indeed, future evolution will happen much faster, on a technological tcilaseme, not a natural selection timescale.

Original Text

And by the way, our special aversion to the risk of truly existential disasters depends on a philosophical and ethical question, and it's this: Consider two scenarios. Scenario A wipes out 90 percent of humanity. Scenario B wipes out 100 percent. How much worse is B than A? Some would say 10 percent worse. The body count is 10 percent higher. But I claim that B is incomparably worse. As an astronomer, I can't believe that humans are the end of the story. It is five billion years before the sun flares up, and the universe may go on forever, so post-human evolution, here on Earth and far beyond, could be as prolonged as the Darwinian process that's led to us, and even more wonderful. And indeed, future evolution will happen much faster, on a technological timescale, not a natural selection timescale.
