Elon Musk on merging SpaceX and xAI and why the moon is the next step in scaling civilization:  "The only way to access the energy of the sun is to extend beyond Earth." "You have to expand beyond the tiny dust mote that is Earth to make any significant dent in using the sun's energy." "In order to do that, you have to go to the moon." "Having factories on the moon, building AI satellites and having a mass driver, is the kind of thing you... read about in science fiction, but we're going to make it real." "I can’t imagine anything more epic than a mass driver on the moon and a self-sustaining city on the moon. And then going beyond the moon to Mars, going throughout our solar system, and ultimately being out there among the stars.” @elonmusk(a16z)
