Developments on something I presented at BarCampLondon 2.
The Uncanny Valley hypothesis has been applied to the visual appearance of CGI characters. It applies to behaviour too.
In fact, there are plenty of things that sit just left of normal and creep us out. Cybernetics and the web are slowly tipping some of us toward behaviour that creeps people out.
Human and AI behaviour are on course to intersect, but it will most likely take a long time. The waters around Turing tests are already becoming muddy though.
