A true AI -- self-aware, with actual intelligence -- is metaphysically impossible. It would have to have an immortal soul, rising above the physical world (as humans do) to gain one of those 2 treasures God gave us, which make us in His image: INTELLECT and FREE WILL.
I'm sorry, but Man can't create something in the image of God! (Reproduction doesn't count, because our contribution to the creation of a new human being isn't really creation on our part. God creates the soul, and our bodies do everything else without our input.)
The closest you could come to being true: some future, highly touted AI system (claimed to be sentient) could have a demon residing inside it. Just like devils inhabited other humble, lowly creations of men (statues, totems, tools, etc.) and gave them their power. Yeah, a devil could give intelligent answers. They do have intelligence, to literally give the devil his due.
Just like the grass skirt-wearing, bone-through-nose primitives didn't question where the statue's knowledge came from ("the god spoke, of course!") likewise today's primitive pagans will say "It was artificial intelligence which gave the answer, of course!") when it was actually a demon in both cases. Everything old is new again!
If it were possible, the devils would be laughing their asses off at us stupid humans. We really never learn.
