In an insightful and highly entertaining Business Insider profile of Elon Musk by Wait But Why writer Tim Urban, the technologist and journalist spend lunch discussing all manner of ideas: genetic engineering, superintelligence, consciousness, etc. Musk says he steers clear of genetic engineering because of its Nazi connection, and of course, he speaks of his desire to launch us into becoming a multi-planet species. An excerpt:

This guy has a lot on his mind across a lot of topics. In this one lunch alone, we covered electric cars, climate change, artificial intelligence, the Fermi Paradox, consciousness, reusable rockets, colonizing Mars, creating an atmosphere on Mars, voting on Mars, genetic programming, his kids, population decline, physics vs. engineering, Edison vs. Tesla, solar power, a carbon tax, the definition of a company, warping spacetime and how this isn’t actually something you can do, nanobots in your bloodstream and how this isn’t actually something you can do, Galileo, Shakespeare, the American forefathers, Henry Ford, Isaac Newton, satellites, and ice ages.

I’ll get into the specifics of what he had to say about many of these things in later posts, but some notes for now:

— He’s a pretty tall and burly dude. Doesn’t really come through on camera.

— He ordered a burger and ate it in either two or three bites over a span of about 15 seconds. I’ve never seen anything like it.

— He is very, very concerned about AI. I quoted him in my posts on AI saying that he fears that by working to bring about Superintelligent AI (ASI), we’re “summoning the demon,” but I didn’t know how much he thought about the topic. He cited AI safety as one of the three things he thinks about most—the other two being sustainable energy and becoming a multi-planet species, i.e. Tesla and SpaceX. Musk is a smart motherf—er, and he knows a ton about AI, and his sincere concern about this makes me scared.

— The Fermi Paradox also worries him. In my post on that, I divided Fermi thinkers into two camps—those who think there’s no other highly intelligent life out there at all because of some Great Filter, and those who believe there must be plenty of intelligent life and that we don’t see signs of any for some other reason. Musk wasn’t sure which camp seemed more likely, but he suspects that there may be an upsetting Great Filter situation going on. He thinks the paradox “just doesn’t make sense” and that it “gets more and more worrying” the more time that goes by. Considering the possibility that maybe we’re a rare civilization who made it past the Great Filter through a freak occurrence makes him feel even more conviction about SpaceX’s mission: “If we are very rare, we better get to the multi-planet situation fast, because if civilization is tenuous, then we must do whatever we can to ensure that our already-weak probability of surviving is improved dramatically.” Again, his fear here makes me feel not great.•
