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
Probably this. Its not easy to do.
I think there is also something to be said about the singularity of vision Musk brought to these companies. Its easy to dismiss (and I haven't been a fan of him much since the whole Thailand incident) but its one of those annoying aspects that eludes the desire of developers' (i.e. the average reader of this site) desire to quantify everything.
It makes me think of the story of Steve Jobs after his return to Apple, where he called a meeting of team leads, made a quadrant on a white board with the edges labeled "desktop" and "portable" on the vertical, "consumer" and "professional" on the horizontal, and demanded the company only produce 1 product to fill each of the four squares, eliminating the rest.
