I wish more people realised the truth behind the PR construction that is Elon Musk and stop calling him an 'inventor' and 'engineer'. He is neither. He got lucky a few times and has somehow managed to persuade people that he 'invented' Paypal (he didn't - and was in fact sacked when X.com was bought), that he 'invented' the electric car (nope, the Victorians did that), that he 'invented' the Hyperloop (again, the Victorians) and that he 'invented' reusable rockets (again, not him). He is a massive fraud and a paper tiger.
