Carmack's Facebook Connect talk last week[1] sure made him sound very plugged into what's happening at Oculus. I was surprised, given that I, too, thought he had essentially left for AI research.
Most of the higher level Oculus engineers are very in tune with what is happening within Oculus and the industry. There is constant discussion internally about it, and Oculus still knows more about VR than anybody else. Source: I was one of them.
I think every non-manager employee these days should be "independent." Some may not have noticed, but tech company managers have gone insane and turned their ego up to 11 echoing the current political climate. Anyone who is a famous dev or even a grunt that shows they have basic competency is going to be an immediate management target.
