I'm obviously not a fan but I agree he likely deserves a lot of credit for this. But at the same time, don't a lot of people participate in hiring decisions throughout a company? The board? Other executives?
It irks me that Musk should get all the credit of what is undeniably a team effort.
If you're actually curious there is a good book on SpaceX early days.
Liftoff: Elon Musk and the Desperate Early Days That Launched SpaceX https://www.goodreads.com/en/book/show/53402132-liftoff
If you read the book I think you'll agree, desperate is the correct word in the title of that book and Elon did plenty.
I still can't believe they're landing rockets backwards. When I took control systems it was the canonical example of an unstable system. Guess those books need updating. :)
Regarding the landing rockets issue, I've found BPS Space's youtube series on trying to land a model rocket in a similar matter very enlightening. https://www.youtube.com/watch?v=miMT44LFUjs
