I don’t believe Elon is even remotely related to a people manager. He’s a stakeholder and operator which require different skill sets. He finds folks who will manage to o bring the empathy he tends to lose in his pursuit of his next project. I believe your evidence may be anecdotally valuable but let’s be clear about the dynamic of a founder/ceo.
Mate, wouldn’t it make sense that these rules are applied via hierarchy? If Elon respects Karparthy he almost certainly gave him a longer leash and Karparthy’s output was strong enough to not warrant intervention. It’s clear he did not want to stay long term so I’m not sure this is a strong line of thinking.
