Ideas are what smart people are good at. Ideas often have tremendous value, but are difficult to monetize in themselves.

These IT guys are good at ideas, and at organizing other people to make money. I'd guess that the top guy running the show is generally not the smartest guy in the room, and in fact, his likely intelligence is limited to a standard deviation less than the general level of smart guys he can put around him. Not that you have to be stupid to be in charge, but that you can't effectively manage people too much smarter than you are, though you do want people smarter people around you.
