There were a lot of engineers making noise about Elon being a complete fucking idiot a long time ago. People were dismissing it as jealousy, but it was one of those quiet industry secrets.
Lo and behold, Elon was never accepted into a doctorate program and there is a bunch of shady shit about him even having a B.S. in physics, looks more like he failed out of the program and got the degree after a large donation from his father.
Elon started believing his own bullshit and exploded himself for being a fucking loser rich kid who has done nothing but funded some projects smart people told him to fund.
