What good has Elon Musk ever done?
He didn't found Tesla - he was a financier, who stole the company from its actual founders, Eberhard and Tarpenning. He didn't found PayPal - he did create X.com, but was fired for poor coding skills plus being a rude asshole, and only after that did it get bought out and turned into PayPal (Musk did own shares in PayPal, but that's it).
As for Tesla, Full Self-Driving is a scam in and of itself, being promised to be "fully functional" in 2017 yet still isn't, being barely functional and very dangerous. The Tesla cargo truck was promised in 2019, and has barely entered production, and important factors (such as how much cargo it can carry) haven't been officially revealed, to my knowledge - sold under false pretences, and isn't nearly as good as advertised or as gas-powered trucks. That special Tesla car barely works too, and their "thermonuclear-explosion-proof glass"? Pfft.
There's also the regular cars, which are known for trapping people inside when they inevitably combust (lack of power locks the doors, idiotically), and are known for spontaneously combusting. Why ever get one of these? Why not get another brand's EVs, one that isn't owned by a manipulative asshole?
Oh, and the fucking robots, which can barely shuffle in a straight line, and any footage of them picking up, carrying, and putting down objects is clearly spliced footage. How is this impressive, when Boston Dynamics and others are leaps and bounds ahead?
Neuralink tortured animals to self-mutilation, disease, and death, all in the vain hope of creating tiny brain implants that would do impossible things (play virtual games, for instance). They tortured and killed numerous monkeys and sheep, and have been denounced by a lot of people and organisations. They also attempted to gain recognition for research that another group had done in the late 2000s. Needless to say, Neuralink is a particularly dark and horrific stain on Musk's rap sheet.
SolarCity was an outright scam, as was the Hyperloop and LAX Tesla-based tunnel dug by The Boring Company. SpaceX is another scam, chewing through insane amounts of grant money with practically nothing to show for it except fireworks, damaged landing pads, the destruction of a wildlife preserve, and forcing Boca Chica residents to relocate.
Starlink ruins Earth-based astronomy, significantly increases the amount of space junk in orbit, and (like all satellite-based Internet) will be slow as shit when a bunch of people try to access it and clog the available bandwidth - plus, there's other competitors that don't need so many goddamn satellites to function.
There was also his ludicrous idea of replacing planes with rockets, from several years ago, which is patently ridiculous as a concept (travellers would have to don protective gear, wait for fuel to be loaded - can't do that beforehand, not safe - and hope it isn't raining at the destination, plus the rockets would have to be far away from cities and stuff due to how loud they are), and considering how explosive SpaceX is...inherently unsafe too, with this guy.
And now he's sinking Twitter. $8 blue "verification" mark, shadowbanning people, preventing reading of Tweets when not logged in, and now rate-limiting those who are logged in.
Then there's how he's treated his multiple wives and numerous children, on top of his business fuck-ups.
So I ask again - what good has Musk ever done?
