Not only is living on Mars a very distant or even impossible prospect, it is based on the idea that Earth will become inhabitable. Ever noticed how Elon Musk seems to welcome the idea of an apocalypse — seen his introductory drive in his Cybertruck with Jay Leno? As if we are all to become doomsday preppers and to use his truck. Frightening frame of mind he has. It is of course multi-trillions time cheaper to keep Mothership Earth habitable (which is already let’s say for 95 percent perfect) than pursuing traveling to and living on Mars which can never come close to what Earth is providing.
