I went to see the new film Ex Machina, about whether a female robot will pass the Turing Test. It is never quite clear whether she is conscious in a human kind of way, even when she is flirting with her examiner. But the matter is put beyond doubt when she turns on her maker and stabs him to death, and then leaves the man she flirted with to die of starvation. It is the existence of evil that proves she is conscious–that she is human. Also, the film contains a nice exposition of Mary in her black and white room. All very philosophical.
