Lex Fridman: belief

…Yeah, a couple billion years to spare. There is a mystery there about why did it take so long with the Cambrian explosion, but that may be again, about these windows. That it couldn’t happen until the window, the planet and the life had evolved together enough that they together opened the window for the next step. Intelligent life and how long intelligent, technological civilizations, I think there’s a big question about how long those last. And I’m hopeful, but in terms of just, I think life is absolutely going to be common, pretty common in the universe. Yeah. I think, again, if I were to bet everything, even in advanced civilizations are common. So, to me then the only explanation is the L. Our galaxy is a graveyard of civilizations. Yeah. You think about it, we’ve only been around, truly when we think about in Drake’s definition, you had to have radio telescopes, that’s been 100 years. And if we got another 10,000, 100,000 years of history, for us, it’d be pretty amazing. But that still, that wouldn’t be long enough to really pop up the number of civilizations in the galaxy. So, you really need it to be hundreds of millions of years. And that raises a question, which I am very interested in, which is how do we even talk about, I call it the billion-year civilization. How do we even begin to hypothesize or think about in any kind of systematic way, what happens to a technological civilization across hundreds of millions to a billion years?…
