Either he is a genius who will change the world or the biggest fraud of all time.
Genius who will change the world? He's never shown himself to even be particularly good at anything other than selling his own hype. At times that hype has allowed him to surround himself with talent (Tesla, Space X), but that doesn't make him a genius just because he attracted enough attention to get actual geniuses doing work for a company.
What's his evidence for genius?
* Wealthy kid who attended high-priced private schools, got through academia with decent marks but nothing exceptional or distinguished.
* Founded Zip2, an online city guide, with his brother and a friend and was lucky enough to sell it to Compaq during the height of the dot.com boom. The product was obsolete and useless within a couple years. Nothing revolutionary or special about it, he just got lucky to sell at the high-water mark when all sorts of mediocre internet products were selling big.
* Used the Zip2 money to found X.com, an online bank with a terribly chosen name. Did such a bad job running the company that his investors replaced him as CEO within months.
* X.com got lucky and merged with the more popular PayPal service. Musk weasels his way back into the CEO chair of the new merged company, but is so bad at it that Peter Thiel resigns in protest and the board is forced to oust Musk a 2nd time. This is just 19 months after he founded X.com, and he's already gotten himself fired for incompetence twice.
* PayPal, under Thiel's leadership, is acquired by eBay for $1.5 billion. Musk still owns 12% and makes a fortune even though he neither founded PayPal nor ran it nor contributed to it in any helpful way.
* Musk uses his PayPal money to found SpaceX and spends $100 million hiring much of the best engineering talent around. Despite a long line of failures that nearly bankrupt the company in their early years, he's kept afloat via massive US government contracts. Other than the idea of building a private company to make "affordable" rockets, there is little indication that Musk is behind any of SpaceX's real work.
* Musk becomes the majority shareholder in Tesla during Series A funding, but isn't actually involved in running the company until 5 years later. By that point, Tesla was already delivering Roadsters. Under Musk's direction, the company has attracted a ton of attention and its stock went through the roof, but he also made misstep after misstep that nearly sunk it, and once again his actual bottom line was largely kept afloat by US government subsidies.
* Musk cofounds Neuralink, a company that has mostly been known for false and sensational claims, animal abuse, and a total lack of ethics. They have produced nothing of value.
* Musk cofounds The Boring Company, a total farce of a project meant entirely to sabotage mass transit plans via false promises. They have produced nothing of value.
* Musk acquires Twitter and turns it into absolute shyt.
So basically, he's:
Founded 4 companies that produced nothing of value (Zip2, X.com, The Boring Company, Neurolink).
Founded 1 company kept alive by non-competitive US government contracts (Space X).
Took over 3 companies founded by other people, 2 of which he managed terribly (PayPal, Twitter) and the 3rd of which he had a hot start and now is on the decline (Tesla).
