Congratulations to the entire Space X team, this is a real accomplishment and I'm sure not one that came easily. It's exciting to see relatively small companies fulfilling roles that people thought might require massive military contractors.
Elon is an interesting figure. He is, I think, a paradigmatic example of the imperfect creator. His undeniable success in difficult endeavors can create an aura of authority for acting within domains where signals about the appropriateness of his judgement are less clear. We've had technical experts lead us down paths that were not, in hindsight, in our best interests (I think of Teller and Von Neumann's advocacy for aggressive action against the USSR). I hope we can move away from the "elon sucks" v.s. "elon is a genius" dichotomy and into a culture of acknowledging accomplishment while insisting claims in other areas be fully justified.
