“Yesterday, Elon Musk presented his roadmap to Mars settlement and the scale of it is astounding. Mind boggling. I have been working on “outposts” for 8-12 people for over a decade because I believed that that was a reasonable size for another generation. This image hints at how comically insufficient my infrastructure would be to support hundreds of people arriving at a time. I literally have to multiply everything by hundreds. Expect entirely new cities from me in the coming months.”
