I'm not sure most people would claim their success comes down to the intellectual stuff. It's just that a certain type of nerd who is also very competent at what they do likes hanging out around other nerds of a similar type. If you read the descriptions of the actual work, at least among the FDEs, it seems striking how much it sounds like a relatively normal consulting engagement — we're not really talking developing foundational new algorithms or infrastructure here. But the kind of person who enjoys working at and does well in places like Palantir probably wouldn't enjoy Accenture. I agree it can veer pretentious, but I think it's more about clustering a certain kind of person together, similar to what you hear about e.g. places like Jane Street.
I agree with you if we're just talking about the people who work somewhere. I would say that the founders I'm referring to certainly at least partially delude themselves into believing that their intellectual prowess encompasses other realms of science, philosophy, engineering, etc. when all they did was create some software. I also do not believe for one second that these founders are actually as interesting as people have mythologized them to be.
