This kinda implies that Tesla and Space X actually are good for the world, which they are not.
He didn't invent Tesla. He was just the majority shareholder who bought out the company, kicked out the actual chief executive-- Martin Eberhard-- and paid some millions on the NDA. Tesla was doing fine without him. Now the company is embroiled in a bunch of work violations for treating it worker like shit under policies directly tied to his leadership. Tesla has not made a profit except for the years where it sells carbon credit; it produces overpriced electric cars that only dominates the market because of the number of fueling stations available; its stock is failing and is considered massively overvalued by most market analysis.
The only thing that he's been successful in is getting the electric cars into mainstream market under the guise of environmental sustainability, but Tesla sells carbon credit and the way it produces cars is actually terrible for the environment. If he really wants to support the environment, he would've invested in public transportation, encouraged better policies making (he has done the opposite), shut up about bitcoin, and supported indigenous communities.
Space X has done nothing that Nasa couldnt, except now it's privatized. They've taken billions in government contract while not doing shit for scientific research.
Whatever minuscule, if any, good him and his companies have done are incidentals to profit making.
The guy's just a rich kid who throws money at idiotic ideas and hope that they stick; 99% of them have not. You're talking about a guy who wants to build underground tunnels network for cars when train exists, thinks that COVID will completely end by 2022 when it has killed more people this year than in 2021 and 2020 in some countries, and says that he'll get people to colonize mars by 2023. You're talking about a guy who was fired as Xcom and Papal ceo for being bad at his job, a guy who says he's “a free speech absolutist” while firing employees for speaking out and supporting rhetorics that violently silence marginalized people. He's been sued multiple times for his illegal business practices. He literally could solve world hunger with his money but instead he bought twitter-- nothing can excuse how morally bankrupt that is.
