Re: Turing test ?

Me for one. Nobody has spotted that I'm a bot yet.
(Serious point; when Turing wrote about that test, we still thought that human intelligence was the only kind of intelligence. It's now obvious that parrots and dolphins are intelligent but not necessarily in a human like way, and that some aspects of human behaviour are distributed fairly randomly among the animals - dogs are good at communicating with people but not as good at abstract thought as ravens, say. So the Turing Test isn't really appropriate any more, because of its anthropocentric assumption.)
