How do you know if an artificial intelligence (or AI), really is sentient? Ex Machina explores this problem with stars Alicia Vikander , Oscar Isaac , and Domhnall Gleeson . From Google: "Caleb Smith a programmer at a huge Internet company, wins a contest that enables him to spend a week at the private estate of Nathan Bateman, his firm's brilliant CEO. When he arrives, Caleb learns that he has been chosen to be the human component in a Turing test to determine the capabilities and consciousness of Ava, a beautiful robot. However, it soon becomes evident that Ava is far more self-aware and deceptive than either man imagined."
