I think that's a little overblown. Certainly Musk has his talents but they are not infinite and as we've seen he also brings a lot of disadvantages to the table as well. Not just these outbursts but many other aspects of his management and working style (not just at Tesla but also at SpaceX and going back to PayPal) are incredibly problematic from the perspective of attempting to run a well functioning company. SpaceX succeeds mightily partly because there are many other forces there to counteract Musk's problems, which doesn't seem to be the case with Tesla. It's also worth noting that Tesla is on a lot shakier ground than many of its fans believe. Tesla's done a great deal to advance the technology of electric cars but the rest of the industry is catching up and Tesla has made some major mis-steps of late (such as with model 3 production). Yes, Tesla would be ill-served by replacing Musk with a typical empty-suit executive, but with a competent and pragmatic leader it would probably be just fine.
