He makes a lot of people mad but that doesn’t make him an idiot. It just makes him genuine. Everybody else who looks polished is hiding secrets behind excellent PR.
I agree that making a lot of people mad doesn't necessarily mean someone is an idiot. At the time time, making a lot of people mad does not necessarily mean someone is genuine.
For example, someone who manipulates a lot of people with misinformation might manifest anger in many. In that hypothetical scenario, I wouldn't think that the anger is because the target's an honest, forthright, genuine straight-shooter.
Furthermore, most people are genuinely kind and compassionate towards others. For those people, mass anger is not their genuine goal, or a likely consequence of them being genuine.
I don't know what you'd call firing the entire supercharger team because the head of the department pushed back on layoffs as anything other than idiotic.
No, I'd say they're running interference for Musk. It's one anonymous source claiming that the media was wrong, and many other fired sources that were willing to step up and say their entire department was axed. Why would I trust an anonymous source?
