At first I was thinking of posting a joke about missed timelines, but then I remembered that nobody else is setting audacious public goals quite in the way that Musk does. So instead of a joke, I'll tip my hat to that and hope its true.
And that's without people. Now add humans to that equation. Not easy.
I mean, we could barely refrigerate food 100~150 years ago and now we are developing technology to build habitats on another planet? How cool is that?
