As some who worked there for 4.5 years, this is an accurate description of the work culture at SpaceX. You sacrifice safety for speed. As a young person it’s an opportunity to take on a lot responsibilities, but at that point in your life you don’t have the fortitude to tell Elon, who does push the agenda directly to personnel, to say you do not deem this task safe/smart/responsible.
Gwynn is a sly leader that tries to balance out Elon and non-Elon agendas, but will capitulate to Elon on a regular basis. You definitely do get fired for delaying any Elon focused project, regardless of the reason, if you’re annoying enough or easily replaceable. If you want to go toe to toe with Elon you better be the most productive person, with a good track record, have a rare skill set or knowledge, and be willing to risk your career.
