AI may not necessarily be portrayed as humanity's successors and replacements in the Marvel Universe, although given the "Robot Revolution" currently playing out in Iron Man 2020 --- with AI lashing out at humanity due to being sick and tired of being abused and exploited by them --- that could very well change, at least in the sense that humans will fear AI as much as they already fear mutants. Funny enough in light of that, Powers of X depicts future humanity as so desperate to overcome mutants' natural genetic advantages that they integrate AI and technology thoroughly enough with their own bodies that they become a new, (perhaps) equally inhuman species in their own right. Fair bit of irony there, I think, but otherwise I do agree that the ultimate point of X-Men is that bigotry is indeed irrational.
