My honest suspicion is that Musk will focus more and more on AI (and less on space) because he sees it as a path towards his immortality. I expect AI models trained on him combined with millions or billions spent lobbying to allow an AI to own and direct a company. I know this sounds like poorly written sci-fi but I will be only disappointed - not surprised - if post death AI Elon is the richest entity on earth.
Maybe Peter Thiel and Elon Musk will meet again cryogenically preserved ;-) https://fortune.com/2023/05/04/peter-thiel-cryonics-cryogeni...
AI + Optimus + desire to explore the universe is such a cool concept. I think he'd love to send his consciousness out after all this bickering on earth.
Honestly, the more that we get humans away from squabbling over the same patch of desert the better off we'd probably be. Everyone seems to think they can spend money better than everyone else.
