HE is not DOING much anything except funding stuff with his money and spouting off racism and xenophobia.
Elon Musk is NOT a genius. He's just a rich kid who took daddy's money and made more with a couple of obvious investments. If you have money and even a whit of awareness, it's really easy to make more money. (Jeff Bezos' ex is the darling of the "philanthropist" crowd because she "gives away" billions each year. Ok, sure. Yet, even with all that "giving" each year, she ends the year with more billions than she started with. At least ol' Jeff is an honest ass-hat and keeps all that he made by leaving the log cabin, working hard, and pulling himself up by his own bootstraps.)
What part of large numbers and interest (economic rent) do you NOT understand. This is not even as hard as 5th grade physics.
DO STUFF. Or don't. But, please don't brag about the money you have because you already had some. And, please, please DON'T consider "your" [advised] investments as a sign that you've actually DONE anything or as a sign that you are a genius. Anyone who does that is just another entitled idiot who has come to believe his own press... and continues to rant about all those "entitled" folk out there.
