The perception of identity is so intimately bound up with the perception of the human form.
I was always into science fiction as a kid. I loved science and tinkering with things.
I have been motivated by this idea since I was a kid that if we invented machines that were created in the way that people are - were aware, have free will, inventive machines, machines that would be geniuses - potentially, they could reinvent themselves. They're not just applying it to other things - they could actually redesign themselves.
If we're going to achieve compassion in the machines and also feel safe with the machines, to raise machines with human-like values, we need to make them human-like by simulating, or perhaps eventually imitating, human beings in high accuracy from top to bottom.
