Just listen to 15 minutes him answering questions in any but the most mainstream (thus: time-limited, chunked into 10-seconds slots) channel and you will see that he has most accurate technical information and numbers and tradeoffs and materials etc. in his head than most engineers with 10 year experience. Say what you want about the stock price, about whether you agree with his policies, about his personality, but if you say something so blatantly obviously wrong as "he is not an engineer", it just tells everyone that you haven't done even a 15 minutes of proper research about him.
