Almost Human Is Worse Than Not Human
A robotics professor drew the uncanny valley curve in 1970 from nothing but observation. His best explanation for the pit at the bottom was a corpse.
The Hallway He Couldn't See
A man with no conscious vision walked a corridor full of obstacles without a cane and never touched a thing. His body knew where everything was. He didn't.
