I wonder about survivorship bias in Musk's case. Lots of fearless people with overdose levels of hubris don't lead successful car and/or rocket companies after all. You could probably make a reasonable argument that those traits helped Elon Musk specifically, but that's different than arguing they're useful traits for success in general. I agree with your point about those traits manifesting negatively for Musk himself, but I feel like that effect is going to be even more significant for entrepreneurs trying to succeed by emulating the 2023 version of Elon.
