Contra to Thiel and comments in this thread, something in my gut tells me Elon is still fairly serious about Mars. If humans don’t make it, then I’m pretty sure within 20 years he’ll be sending off teams of Optimus robots to walk all over it and set up a camp. Then who knows, even though Mars is inhospitable in the extreme. I think he’ll at least try and build the Mars base and then see. Also there’s no laws on Mars - Earth treaties are irrelevant at that distance so he really could set himself up as the overlord and Emperor of a whole planet. I think that’s actually his dream.
Also, anyone find it strange that he’s never been up in one of his own rockets? Unless he’s done it in secret without telling anybody (not impossible to believe even though he loves publicity) he seems pretty shy about taking trips himself. Or paranoid about dying in his own Promethean creation.
