It could be that his "save humanity" schtick actually attracts the wrong type of talent. See, when I was a full time programmer, about a decade ago, I really believed in Musk. It was only later, when I had more time on my hands that I started to fact check his claims, resulting in spiraling disillusionment.

So, I think Musk companies must be recruiting people who are young, and somewhat niaeve. I can't imagine many mature engineers being attracted to the crypto-bro atmosphere, unless they, themselves, are as conceited as Musk and happy to be in on the con.
