Then you've never watched any of Elon's interviews where he lays/discusses out designs of products and production lines of all of his companies in great detail?
I don't get how anybody can write "he's not an engineer". It makes 0 sense and kind of proves my point about anything to just rant on Elon another day.
Amazing that people sign up to be verified on Elon's tarpit and they funnily haven't heard anything about how Elon rewarded loyalty and perseverance there (hint: with a boot to the backside)
