[startrek] in one of the early Enterprise eps they encounter a race that have primitive holodecks that can't simulate people, just landscapes. they can simulate entire virtual cities than can fool humanoid perceptions, but they can't create an AI good enough to convincingly imitate a personality?

Yes. A realistic AI takes a lot of computing power, and also a lot of knowledge of psychology. A realistic-looking landscape doesn't take nearly as much computing power, especially if most of it isn't moving most of the time, and requires no more understanding than basic physics and material science.
