>SpaceX employees take the Musk fundraising and spend it well. They have systems in place to minimize his technical interference.
Sounds like nonsense used to wave away his success with SpaceX.
If you look at his interviews, it seems like he is most involved in SpaceX of all his ventures. He can explain deep technical details of the product whereas this is less true for Tesla and has been proven many times that he cannot do the same for Twitter.
