I get the feeling Elon might need someone to reign him back on some of his tweets. I've heard he suffers from bipolar disorder, which, even if medicated, can sometimes flare up.
If that's the case, and some of his episodes bring this about, he really does need to either recognize this in himself, and exert some self-control, or straight up have someone else check it over.
This is especially dangerous because, since his companies' valuations are so intrinsically tied to his 'cult of personality' (I'm using this term neutrally - I believe 'both sides' will agree that a large percentage of Musk's companies' valuation does come from his bombastic personality and presence), this behaviour can only damage his work, which may put him into a negative feedback spiral, with each subsequent outburst plunging it all further down.
