It seems to me farmore likely that a robotic existence would not be like a human one inany sense that we understand, that the robots would in no sense be ourchildren, that on this path our humanity may well be lost.
Here would be a good place to give a solid definition of humanity? What makes it special beyond the "self"?
We are genetically very closely related to great apes and chimpanzees and less closely to dogs, cats, and even rats. Do we miss our dogicity? Or ratanity?
What if the robot/human mix is somehow even more interesting and transcendent than humanity? His negativity doesn't leave any space for this possible eventuality.
