I really hope he can get SpaceX back on track this year.  If they have another failure we&#x27;ll see an endless stream of stories about how Musk should have known better than to split his efforts over two companies, and how rockets that don&#x27;t cost a billion dollars can&#x27;t possibly be safe.<p>Tesla... well, we&#x27;ll see when the Model 3 comes out.  That will be the dividing line between the producer of overpriced toys for rich people (and Norwegians) and a maker of mass market cars.
