"The self financed genius"
Take Elon's schlong outta your mouth and come up for air....you're turning blue.
I'm a fan of both Tesla and SpaceX but this 'self financed' stuff is Musk PR and also nonsense. He's been happy to accept billions to help his companies along. His $260 billion net worth allows him to do quite a bit of self-financing Now. But he's been bailed out numerous times on his journey.
I'm happy to have a rich nerd doing really cool tech projects, though. Instead of just building bigger yachts.
And no, I don't think what you described in your post is any sort of 'war' between him and NASA. They really have 2 different objectives now. He seems to be a genuine space enthusiast and I think he will be thrilled to see the SLS launch.
