So do you just go around making up stuff so it fits your world view?
Elon is the chief designer and chief engineer at SpaceX. If you watch the video referenced in this article and are not convinced that Elon does engineering, then I don’t know what to tell you.
He hasn't designed or engineered anything. He doesn't have an engineering degree. Giving yourself a title of engineer at your own company doesn't make you an engineer automatically.
You're just completely wrong, and judging by your comment history, you have a huge bias against Elon Musk and Tesla so trying to have a real discussion with you on this subject is impossible.
