People can't think themselves, they think: If Elon Musk says that something is good, then it's good.
A man with results, is a man with a voice. It is a regular behaviour for people to listen to
the advice, tip, warning, and whatever a man with results ( a successful man) has to say. Elon so far is a symbol of success, he has driven innovations and is the one of the world's richest men. Alot see him as mentor and till he no longer has results, people will continue to follow his thinking. (After all it is a $182.9 Billion dollar thinking, lol).
