I have bought drinks for Tesla engineers and have known that they were a terrible company with spit and chewing gum holding them together for years now. I think the point that broke Elon’s brain was the Model 3 shitstorm that could have cost him almost everything. I believe he admitted to Kara Swisher that he was sleeping at his desk for half an hour per night for weeks on end because of the amount of speed he was doing. He was always an asshole, but it was after that incident that he just went completely unhinged.
