I'm not suggesting Morrowind characters had AI; heck, they barely even more! I just pointed out that nowadays, the time (and money?) spent on voice acting narrow the choices that will appear in the final game into very few. I bet there are ideas - I guess our world's spontanious actions are the main goal - but those ideas can't be executed as long as there's a need to VA everything in. Even with RAI it would be very hard since there's still too much content to voice act. Maybe we could get a lot of bodily reactions, but then they would be silent. A major problem with Skyrim is they lack many, many, MANY of those bodily reactions as well, even though it was promised they don't. 
And I bet only important/visible characters get those above mentioned "packages" right now? I don't see a Random Bandit X having this package. He just blindly, and stupidly, attacks me, no matter what, and even his lines can sound very off the mark.

I do get your point about voice acting though. However I think reactions are a lot better than Oblivion, and it's just something that will hopefully improve further in future games.
What game have you been playing?!?! Certainly not Skyrim, the AI is a joke in that game.
The AI in Skyrim causes people to play one-man musical chairs, stand in the rain all day, stare at dead bodies then continue on sweeping the floor, tell me they work for Belethor at the general goods store 50 times, develop severe agoraphobia when married, and attack dragons with an iron dagger.

Dialogue has nothing to do with AI. That's just the lack of dialogue lines recorded. However I agree combat AI is a bit dodgy sometimes, but it always has been. The game was never promised ground breaking AI (that was Oblivion's E3 demo). It did however promise NPCs with schedules, decent combat AI and NPCs that react to what you've done. I think it does all this fairly well.
