Reminds me of the Mass Effect games, where AI is essentially outlawed (because they revolted against the humans of course, but I can picture less scifi-ish reasons in the real world). I'm sure they're still allowed to use pathfinding algorithms and such, so they probably defined a level of net negative (to society) AI and just regulated that. Starships for example are manually piloted (surely with intelligent support systems and basic auto pilots) IIRC.
