I think you're right on the AI, and I think Google agrees. https://ai.google/

Problem is, while there's certainly money in applications of AI (the ad auction is one of them), it's unclear that "AI" as a discipline is a money-factory like ads is. Google's looking for a money factory to replace ads because they're worried about that revenue stream being fragile (for the reasons ocdtrekkie highlighted).
