Oh come on. "Übermensch" is a concept from Nietzsche, a goal for humans to achieve. Yes, Nazis tried to appropriate this term for their twisted ideology. But this is HN, I think we can expect more from ourselves here than just pattern-matching things like "referenced by Nazis -> Hitlery -> Evil" (though I won't object the "Uber = Evil" patternmatch). Nietzsche had ideas worth discussing, and the evolution towards becoming superhumans is not an inherently evil thing.
