Musk has no engineering degrees, has never worked in any engineering capacity, has no patents under his belt, and has constantly run into engineering blunders directly attributed to his lack of understanding in SpaceX and all his other businesses. I think you are delusional if you think Musk has any more engineering knowledge than a highschooler with a B in science, nothing he has ever said or done has shown otherwise. On top of that I have seen numerous stories out of SpaceX itself that Elon has to be distracted away from anything important because he thinks he knows better than people with decades in aeronautical engineering.
