People love to give her all the credit, just to discredit Musk. She was doing sales for the first 8 years of the company. Surely an important job, and she is of course great, but to claim she is some overwhelming part of the success of SpaceX compared to Musk is to much.

Of course all the early people, Shotwell, Mueller, Königsmann, Bazza were all really important. Shotwell by now being the the most important.

But there really is no question that Musk deserves by far the most credit.
