All these posts and only 3 mentions of Amadeus Cho and none stating that he should be the guy. He is the new Mastermind Excello and is pretty much supra-intelligent. The kid gets ZERO respect.
So just like from the posters here he didn't get any respect from the CMU. The producers implied that the Professor Cho from the Avengers 2 movie was Amadeus' mom but no mention of a son. So the creators get what they wanted, kinda make that character linked to a real Marvel character but don't have to have an Asian guy in the movie but instead a more palatable female version.
