The stuff in computer games that makes NPCs move around the game world from point A to point B has been called AI for ages (and in this case specifically, is generally the A* pathing algorithm which isn't even all that complex).

It's only recently that marketing-types, salesmen and journalists with no actual technical expertise have started pushing AI as if the I in the acronym actually meant general intelligence rather than the "intelligence-alike" meaning that it has had for decades.
