What does 'post human' mean? Unless we go extinct, we will always be humans, regardless of what species we evolve into. Our current species is "Homo Sapiens Sapiens", not "Human". Ergo, if we evolve into amorphous blobs of space goo, we will still be Human but not "Homo Sapiens Sapiens". Which means it is physically impossible for us to ever reach a "post-human" stage.
