In their words
I would like to apply the same arguments with animals to robots, that they deserve rights in that sense.
I would like to say that the display of it is what makes it real.
There's so many mysteries, there's so much uncertainty. This is our best available like a best guess.
When I interact with legged robots, I see there's magic there, and I just feel like the person who hears the music when others don't.
