Elon believes that only problem humanity is facing is how to establish colonies on Mars. He also believes that no one else is going to fund it, so had to acquire tons of money to do it.

I think it’s BS, but those are pretty much his believes.

Somewhat closer to Earth and immediately necessary for civilization's future.
