Earlier this week I attended a workshop where someone gave a talk about early animated films. The talk also included a reference to the so-called "Uncanny Valley" hypothesis. Since I had never heard of it before, I had to look it up, which is odd given that the hypothesis has been around for more than forty years now. In 1970 the Japanese roboticist Masahiro Moti published a paper, in which he suggested that our positive feelings towards a robot steadily increase the more human its appearance becomes, until, that is, we reach a point where the robot looks almost human, but not quite. Then sympathy quickly turns into revulsion, that is, the sympathy curve that up to this point had steadily risen falls suddenly below zero, before it rises again with equal suddenness when the robot becomes indistinguishable from a human. The term "uncanny valley" refers to the sudden dip in the sympathy curve. In 2007, Jamais Cascio speculated that we might experience a "second uncanny valley" once we have started to radically enhance human beings. The slightly more than human might be as uncanny as the slightly less than human, while we might be fine with sufficiently distant posthumans.
