Naturally Nietzsche was there first:
As quoted by Steve Hsu:
All beings so far have created something beyond themselves; and do you want to be the ebb of this great flood and even go back to the beasts rather than overcome man? What is the ape to man? A laughingstock or a painful embarrassment. And man shall be just that for the superman: a laughingstock or a painful embarrassment. You have made your way from worm to man, and much in you is still worm. Once you were apes, and even now, too, man is more ape than any ape. What is great in man is that he is a bridge and not an end. -- Thus Spoke Zarathustra
Of course I found Nietzsche's Superman rather revolting - to the extent I understood it. But now we are faced with the prospect of really trans-human creations, either as genetically enhanced humans (not very likely, I think) or some sort of cyborg (still not likely) or robotic (likely) replacements. If such replacements deserve their place, though, I like to think that they will see their predecessors as perhaps pathetic but still heroic.
