> If Musk just stuck to SpaceX and Tesla, a lot fewer people would have problems with him. The issue is that he comes across as a smarter-than-thou narcissist who needs to "solve" every problem [1], can't stand being told to shut up (cf. coronavirus restrictions, or the Thailand cave rescue incident), and generally acts like a petulant asshole.

Even if he "just stuck to SpaceX and Tesla," he'd also have to stop over-promising to the point where he seems like a pathological liar.
