Obviously he is wildly optimist About timelines, but you can’t deny SpaceX have done incredible things that literally every expert said was impossible.
I still like his quote “SpaceX makes the impossible merely late”
Fully self driving cars and people on Mars will happen. And I feel pretty certain Tesla and SpaceX will be at least a bit responsible for pushing it to happen faster than if they didn’t exist.
Of course they are not perfect, but on the whole I think we’re better off because they exist.
