> I also don't understand how we think we'd do better on Mars than on Earth. We have near infinite resources and advantages here and we trashed it. We have none of those on Mars. Elon's goal isn't to do better on Mars. It's to have Mars as a backup of humans in case something happens to Earth (for example - big meteor). As we sit now if we lose Earth, humans are finished. If we had a colony on Mars, at least humans as a species would continue.
