After the many years, there have been insider voices indicating that success was despite Musk in many ways. Musk bought his way into cutting edge tech, it succeeded despite him due to the already amazing people working in the industries. The projects that have his actual involvement are pretty regularly seen as mistakes or flops.

I personally hold to the idea that whoever at SpaceX crafted the team used to pre-occupy Musk and keep him entertained while the rest of the company worked, is largely responsible for its success.

I'm not convinced he's all that smart. Space datacenters seems like an unbelievably stupid idea to me, and I cannot imagine anyone who is ostensibly surrounded by tech seriously considering it. Well, no one sober anyway.
