For action games, we're still fighting enemies who do the same 5 to 10 attack patterns. Combat is about learning these patterns and reacting to them.
AI in fighting games still relies on input reading and they still fall to the same patterns. Why haven't we had AI in fighting games that adapts to players playstyles and feels like you're fighting a human(like how the turing test tests how human it feels to have a conversation with an AI)
Or why does AI NPCs in RPGs and open world games still follow the same static behavior from Oblivion/Skyrim? There's a reason why people found Starfield so clunky. And why are NPC dialogue still scripted? I'd imagine we could be having dynamic concersations generated by AI by now
