Totally understand why he might anger you, he does have an ego. But it's the enemy in all of us and it's 100x more difficult to contain when one of the most influential people on the planet.
He doesn't have to be your hero. I definitely don't like the way he's treated some people. But to knock him down completely is a backwards way to look at things.
He was the first to actually mainstream electric cars and they will be affordable one day, which let's be honest is basically impossible. Now, every single car company on the planet is making one. SpaceX was also the first to send a human to space from US soil in over a decade. NASA was sitting on their ass and it took Elon to make it happen! We once again believe in space exploration. Not only that but he cut the cost of launching a rocket by half! Now that really is impossible.
