Sorry, I should have clarified: the engineers at SpaceX are good, and don't think they are doing anything wrong. I'm not meaning to ignore or discredit their accomplishments.

My comment was directed towards Musk, specifically. He has a track record of overpromising and underdelivering, throwing out the baby with the bathwater, fighting regulations, and chaos testing in production—across almost all of his ventures. SpaceX succeeded despite him, and he shouldn't be followed as an example for a leader of any organization that intends to send flying metal full of fuel into the atmosphere.
