The Iron Man thing… MCU Tony Stark wasn't as smart as he thought he was. He should've allowed surgeons to help with his heart immediately, rather than the entire B-plot of Iron Man 2; Iron Man 3's plot could've been averted in a whole bunch of ways if he'd been less arrogant and thoughtless, and also shows him as a loner unwilling to call for assistance despite (by this point) being allied with what passes for gods in the MCU; Ultron was his own hubris punching him in the face; the justification he gives for the Sokovia Accords was a stupid response to an act of self-defence that, sure, could've and should've been handled better, but it isn't like Stark himself was great at avoiding collateral damage during emergencies in the other films; his rage-fight against Barnes in Civil War, while understandable, was wildly unprofessional and a sign he was not a suitable person to be in possession of a one-man weapon system like the Iron Man suits have been shown to be; his tech gift to Peter Parker had wildly inadequate safety measures to be gifted to someone still in school, even if they had been to space.

Basically: yes, Musk is just like Stark. Half as smart as he thinks he is, has main-character syndrome and/or narcissism.
