You hit the nail on the head in explaining this dynamic, but I hate the fact it exists in the first place, in game dev or IC. It also exists with US special operations, as another way to sort out anyone who isn't a true believer.
Fair, you might say. I just think it's dumb a Google/Netflix/Facebook engineer working on some boring cog in their company's infrastructure gets paid a top-of-market $250k+, while an engine programmer working on an AAA title makes half that, or a firmware engineer working on offensive cyber payloads makes half that, or a special operations solider makes half that.
Maybe it's just market demand: boring stuff is paid better since everyone wants to do something exciting. But I think it's also a filter, and a lot of these places know that.
more this, and less "tools beyond anyone else's reach".
A fair number of people go to work with these groups to "check the box" that they've done it. They know who's at NSA, or CIA, or DARPA. Because they spent 2-5 years with them inside the box. There's a tremendous amount of self-confidence that comes out of a successful turn at one of these places. You know you know.
