Sounds like so many complaints about the enterprise software landscape, and has certainly proved to be true in my own experience. Codified processes usually start with the guise of open communications and education, either because someone wasn't thinking or because of a pressing need to get a few people on the same page. They are soon adopted and enforced as dogma by natural-born bureaucrats who crawl out of the woodwork from seemingly nowhere. It must be an incredible challenge to fight in any large organization, looking at it from the top down.
So far, Musk appears to be doing an admirable job. These things tend to last only as long as a real visionary is at the helm. He is young so hopefully can keep at it for a while longer still, hopefully even long enough to get us to Mars. From this article, he didn't actually say to much about such plans. I wonder if it's just a judicious amount of prudence on his part or if even he fears it may not be feasible in his lifetime.
