I kinda get that vibe too. But without knowing more about him, I imagine what I perceive might also just be someone who’s very confident in themselves who doesn’t necessarily care very much what others think about him. Which, Linus has built his own company from the ground up, and it has made him very wealthy, so, he has some legitimate reason for that confidence, in his competence and his f you money. I suppose that might also co-occur with easily overlooking other people’s problems, or being narcissistic though. Which is bad for a boss (e.g. Elon). Still, hard to just summarily judge without more information
