Last week, Saya the robot made her teaching debut in Tokyo. She is "multilingual, can organise set tasks for pupils, call the roll and get angry when the kids misbehave." I'm sure Saya would fail it, but it seems pretty clear that the Turing test is either obsolete or near enough to it not to matter. These days, nobody cares whether a machine can pass for a human. Instead, Turing's been superseded by the far more pressing Turing 2.0: can a human pass for a human?
