Musk aside, I think there is huge value in knowing how to sustain human life indefinitely without the earth. In fact, I think its inevitable that humans will need to leave earth at some point in our future.

It may simply be as a result of population and overcrowding, it may be to flee war and persecution. I think there is a small chance we have already made changes to our atmosphere that make life here incompatible with humans.

Its possible that within just a few hundred years, humans need to live entirely within climate controlled environments. If I had Musk level money I would be working on this now.
