Ex Machina is a 2015 British science fiction thriller film written and directed by Alex Garland.
Ex Machina tells the story of Caleb, a young programmer who wins a competition to spend a week at the private mountain retreat belonging to Nathan, the CEO of the company he works for. On arrival, Caleb is asked to administer a Turing* test to an android in a ground-breaking experiment around artificial intelligence.
The film received positive reviews worldwide.
*The Turing test is a test of a machine’s ability to exhibit intelligent behavior equivalent to, or indistinguishable from, that of a human. Alan Turing proposed that a human evaluator would judge natural language conversations between a human and a machine that is designed to generate human-like responses. The evaluator would be aware that one of the two partners in conversation is a machine, and all participants would be separated from one another. The conversation would be limited to a text-only channel such as a computer keyboard and screen so that the result would not be dependent on the machine’s ability to render words as speech. If the evaluator cannot reliably tell the machine from the human (Turing originally suggested that the machine would convince a human 70% of the time after five minutes of conversation), the machine is said to have passed the test. The test does not check the ability to give correct answers to questions, only how closely answers resemble those a human would give.
