I really enjoy the underlying element of social commentary in this one. The take on 'human' is wonderful, I like how the unity that encompasses all, robots and mutants included, is what has lead them to term themselves as a new iteration of human. It is a clever way to go, it isn't one mutation that has changed them all, but the acceptance of divergence, made for a great story. Although I very much hope the road to acceptance of difference doesn't turn out to be so hard fought.
