Oh it's worse than you think. I had the mis(fortune) to talk to META VR and AR engineers at one point. I was stunned, as they are asking semi-technical questions, to learn they had little to no experience with VR or AR itself. They didn't even use or care about their own products! Further, they had this aura of "I'm too superior ro use VR and AR that's for nerds". It blew me away. The entire group was run by marketing/politics masquerading as basic engineering. Mark was too nice to them, and let them take him for a ride.
