And i would like to add. Compare SLS from Boeing and NASA. Has the world ever seen rocket development using an agile itererative methodology. His engineers must love him! If you were 25 and working on Starship that would have to be a dream job. Think about the standups, retrospectives and sprint planning they must be organising (why did it fail, what can we try next, how can we improve...), very very exciting if you were lucky enough to work there.
And, I am trying to say it's not all about Elon, it's about the people who work for him. If it succeeds it will be his vision (guidance and money) and their hard work.
It's his project and he is allowed to set his own goals!
But, I am a bit disapointed that his stainless steel Starship has visible welding lines and bumps in it...
, but then I am happy with my ute and that has plenty of bumps and scratches.
