That's basically the entire history of artificial intelligence. We used to think a robot capable of vacuuming your house would be "AI" and now roombas just bounce around the floor semi-randomly. The task didn't change, our respect for it did.
At this point the definition of AI is practically "Something computers can't do yet", though I'm partial to its corollary "Any sufficiently misunderstood algorithm is AI."
