This is not a super-villain origin story
Although it sounds like it, its roots have to be much deeper. Elon Musk sees his children as props that he spends little time with, pumping gametes into his serial wives and throwing money at them, and it’s unsurprising that at least one of them wants nothing to do with him.
P. Z. Myers has an error in that first paragraph, where he refers to Vivian as Justine. Otherwise, an excellent piece on Musk and how he treats his transgender daughter.
