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.
The perception of identity is so intimately bound up with the perception of the human form.
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.
I was always into science fiction as a kid. I loved science and tinkering with things.
