Given the computational complexity of photo-realistic CG, how does the NASA conspiracy produce hundreds of thousands of perfectly faked photographs, videos, and (most importantly) live feeds. Keep in mind, the latest CG movies take on the order of 60 million render hours, and these movies need to make tens (or hundreds) of millions of dollars to be profitable. NASA gains no income from this better-than-ILM CG.
