He is more MBA than engineer at this point. Just because he doesn't have the letters doesn't mean he isn't deploying the knowledge and approach of an MBA. His companies have successfully deployed plenty of MBA-style strategies and their "creative" financing/PR indicates this. I'm not disagreeing with the premise of his argument (I actually agree to an extent) but using his public voice to downplay the expertise of a large group of people is... odd. Fundamentally, his businesses have plenty of weak spots and maybe criticizing the credentials of those who criticize his businesses is a valid strategy?
