> That said, I was surprised to learn much later that, by all accounts, Elon Musk was a competent and resourceful leader in SpaceX's early days. Maybe these stories are just his personality cult in action, but I found it plausible

He's good at having and raising money which was what SpaceX needed, I think he was probably the same then as he is now. Reading about his early days at Tesla and the PayPal stuff, I don't really buy the idea he was ever different and took a dark turn. He's the type of person that will never self-regulate and somehow has never faced any negative consequences for lying and self-aggrandizing so has kept pushing it further
