You need to stop thinking of Musk in terms of a person who has "done amazing things" and letting that lead you to a belief that he has some kind of special ability in this space.
He's the money guy. He's occasionally managed to acquire talent that has done amazing things. This does not give him an innate "make amazing things happen" ability. He can throw money at bad ideas and ineffectual people. He can make something happen given the size of his wealth, but whether that actually achieves any of the stated goals is largely independent of his own actions.
