The simple state machines and decision trees that make enemies move and attack in video games, we also call AI. AI is a loose term and always has been. It's like the term "robot": we call any machine a robot which either a) resembles a human or part of one (e.g., a robotic arm), or b) can perform some significant human labor that involves decision making (e.g., a robot car that drives itself). Similarly, AI is anything that makes, or seems to make, judgements that we think of as the exclusive purview of humans. Decision trees used to be thought of as AI, but today they are not (except, again, in the context of video games where they're used to control agents intended to seem alive).
