Here's the son if someone else! /s

James Murdoch is good friends of Elon Musk.

So it is technically nepotism.

To an outsider like me it would look like a position awarded due to being a son of a powerful/rich father with relevant experience awarded the same way in another corporation (how likely is to become a chief executive in young age on own merit?). That would qualify it as a nepotism (father as investor to son); if Elon is a friend, then also cronyism. I have no hope in companies ran in such fashion; they can't survive Darwinian environment, bad decisions would accumulate in time, leading to larger and larger monetary loss, prompting fund withdrawal to cut the losses at some point.
