Please look at all the crazy tweets he posted [1] in the last few years, he is a manipulator and a liar.
I do think Elon is a bit of a troll, and also that he is prone to saying things that he thinks are probably true without really verifying them fully.
I think that he says things on social media with approximately the same level of internal surety that you might apply to talking to a friend in a casual situation.
You might be quite willing to say to a friend “we are going to finish the X project in 6 months” without really calculating the odds of that actually happening, and without your friend calling you a liar in 6 months when that doesn’t happen.
Now you can argue that he should apply a larger degree of rigor when positing on social media because he is a famous person running a big company, and maybe so.
But he might also argue that why should he be held to a higher standard on Twitter than any random joe posting garbage to thier feed for friends to read?
Because he is an influential spokesman for one of the highest valued stock market traded companies in the world, and a throwaway comment can cost billions. I mean sure, if you're cynical enough you can pooh-pooh it as monopoly money for the 0.01%, but this same monopoly money fuckery caused the 2008 financial crisis. If he 'accidentally' crashes Tesla, that's hundreds of billions disappearing into thin air. Monopoly money, sure, but it'll drag down a lot of others - including things like pension funds.
Musk is relevant because of Tesla, SpaceX, Starlink, and possibly a few other companies in the works. Maybe he gets some credit for PayPal too. Any one of those things would be sufficient to make his twitter personality a minor footnote in history.
Vast overstatement.
He also calls people he disagrees with "pedos" and posts Hitler memes on twitter about vaccinations
