In Avengers: Age of Ultron,
Ultron was termed as an AI (Artificial Intelligence). Okay, but why was everyone (Avengers and Nick Fury) scolding Tony for developing an AI in secret? Doesn't Marvel Cinematic Universe already have AI? JARVIS is a famous example of an AI. My theory was that Ultron simply had different morals than JARVIS. But, it turned out that Ultron was somehow special. How?
I am not involving Mind Stone here. I am talking about the Ultron program only.
Later in the movie, we saw that
Tony was able to boot JARVIS into Mind Stone's computational matrix. So, how is JARVIS not same as Ultron? How exactly is JARVIS not a real AI?
