Fairly superficial treatment of a rather fertile topic. The best way to know the documentary went nowhere is to ask yourself if you see the matter differently or if you got new insights; I know I didn't. Countless minutes pass seeing an academic wonder if the silicone seems real enough.
Materialists and their neo-Cartesian mind/body duality can suck it -- the mind isn't some equation that can be separated from the body, it IS the body. And what's this nonsense about Japan, birthplace of the ostentatious mecha, trying to pass off a spectacled piece of immobile silicon called a "geminoid"?
