I imagine the prospect of being able to play with genuinely unbelievably good equipment has to help when recruiting - e.g. think of the amount of physics, signal processing, aerodynamics, mechanical engineering, materials science etc. used to blow up a plane 50 miles away in a modern active radar guided missile.
I could easily flip the question around:
Who are these people both smart enough and dumb enough to work at FAANG companies?
The individual components are well engineered, it's the integration that is completely flawed.
