It's my understanding as well, many things that a modern programmer thinks in term of "computation" were once considered to be "AI". Lisp and Prolog were "AI", even the A* algorithm is still considered a rudimentary form of "AI" in textbooks just because it uses heuristics. There's a joke that says "every time AI researchers figure out a piece of it, it stops being AI" [0]. It's why I use "AI" and "ML" interchangeably although I know it's technically incorrect - the formal definition doesn't match what people are currently thinking.
