Anyone who has read the biography of Elon Musk will understand, because you will find that this person is very complicated. Some people say he is a liar, some say he is a genius, some say he is a madman, and some say he is a pioneer.
But one thing is undeniable, he is very arrogant, so arrogant that he looks down on the earthlings, which is also the reason why many people are unhappy with him. But looking back at the things he has accomplished, if you take any one of them, I guess you will have to walk with your head held high. First of all, he built SpaceX. Although it is an improved technology based on Nasa, the cost has been reduced by 90%. This is like the car was invented by Mercedes-Benz, but the assembly line production method was invented by Ford.
