[Marvel] Is true AI possible without magic intervention?

Are there any examples of a true AI, who’s creation did not involve any kind of magic?  

For example, I think Iron Man’s Jeeves is close, but (and correct me if I’m wrong) he isn’t a fully sentient person.

Ultron is a fully sentient person, and an AI, but was created with the magic of the Infinity Stones.

Yes, we actually see how JARVIS compares to Ultron and while Ultron is a lot more sophisticated thanks to the mind stone the difference is merely a matter of degree and not an overly huge one. Remember that JARVIS was still sophisticated enough that in a severely damaged state JARVIS was still capable keeping Ultron from getting control of the world's nuclear stockpiles, so that's hardly a sign of Ultron being all that far ahead.

I think it's just a matter of iteration and upgrades to get Tony's AIs up to the point of self awareness.
