Lesbian Robots and Future Morality

If you're interested, here is a music video for the song All Is Full of Love by Bjork.

It might be a teeny bit NSFW as it contains "Lesbian Robots", as one person put it, but since they are only seen kissing then it's largely safe viewing in most contexts.

Because of where my head is at the moment, when I saw this it suddenly made me think about human behaviours, dispositions and intuitions, and moral behaviour in light of that.

Why?

Well, why would robots kiss at all? It serves no function, no purpose, in the life of a robot. In fact, presumably a "Lesbian Robot" doesn't really "love" the other robot that it is mechanically entwined with. All of it is an empty shell, replicating the behaviours of the ones who were (indirectly/originally) their creators.

I can imagine that such an automated factory could go on producing robots long after the human race had died out. Would they continue to love and continue to kiss? Would they make more robots in kind with themselves, who in turn keep repeating scores of pointless rituals that echo some long dead, human meaning?

How much of our behaviours are also echoes of our past? How much of our current disposition and our intuitions are shaped by archaic biological and social forces no longer relevant to our modern lives?

How, then, does our resulting moral tendencies and opinions reflect the best correspondence with reality as it can be optimally reached (and how much of it is harmful or confounding echoes)?

Being 'objective' is the golden child in moral discourse, it seems. Surely a truly objective morality would reach beyond our primal proclivities and emotions. Surely a truly objective morality wouldn't look very human at all beyond the necessary attachment to us as moral actors.

I wonder then, what would a transhumanist (post-human) morality look like?
