I genuinely don't know how the mental model of such a person works where they look at Elon who got multiple world changing bets right but they focus on the ones that were wrong.
Starlink + reusable rockets... alright, not bad, but not exactly a "world changing bet". Seems far more hyped than anything. So he gets credit for just combining the idea of reusable rockets to send satellites into space? okay fine.
He had a lot of money and threw a lot at the wall to see what stuck. If I were a betting man, I'd bet against his "next big idea". He'll over-promise and under-deliver.
Musk didn't originate Tesla's car concept. He did, however, promote into a large scale business. That's the real achievement.
Promotion isn't enough, though. I heard Shai Agassi of Better Place speak once. That was the Israeli guy with the car battery swap startup. He was really good looking, a great speaker, and his 10x growth per year business plan was utter bullshit. Better Place went bust. It wasn't a totally unworkable idea; there are successful battery swap operations in China. But he spent time and money schmoozing with heads of state and setting up demo centers in multiple countries, while not delivering much.
(More fundamental problem: battery swapping is a bet against fast charging and battery progress, which appears to be a losing bet.)
But the people who focus on his successes always seem to downplay, blame-shift and defend when it comes to his negative side. They'll never admit he was wrong about anything. It's the same worship / cult of personality that affects politics too.
