I teach the 8th grade and I agree. Have so many folks been telling him he's such a bad ass for so long, he's convinced himself he's infallible? Maybe Musk is proportionally terrified, in comparison to his ego, that he'll be revealed to be a human that makes mistakes, rather than a real life Tony Stark. In order to protect the sanctity of the "Uber Elon" image, he finds it safer to pick on weakness around him.
Very 8th grade.
