That you are comparing Rickover's nuke program to Tesla and SpaceX kind of illustrates the cultural gap. Anyone at SpaceX ever get jailed for whatever reason his/her boss dreamed up off hand? Any analog to Skipjack at Tesla?

Think about that, today, Tesla and SpaceX are "tough" environments to people.

It's kind of a sign that a lot of people today have no idea how things worked back then. We will definitely have trouble bringing those environments back.
