John Carmack is definitely one of the world greatest game designers. They are the only company that made a full ray-tracing version of their game just for Intel to demo their CPUs.
He might be an idiot in terms of change in technology, ie his hatred for multi-core processors, but he does figure out what he is doing with all released technologies. I wouldn't be shocked if he could figure out how to get Crysis to run on the iphone.
