A great movie about AI and human desires. Not like a typical AI movie talking with moralities and some AI theory, it talks this topic in a unique angle--how human perceives AI and the opposite. There're 4 main characters in the movie: 1.the boss of the AI 2. the tester Kello company Nession 3. the AI Ava, 4. the partner AI Kilko. Role 1 and 2 stands for an angle of human's desire or understanding of AI. The first one is crazy for intelligence and wants to make a robot to past the Turing test. What more important is he has no emotional feeling on AI, in other words, AI is AI no matter how capable and how similar to humans they are. The second one is more emotional and cheatable--a "kind: human who doesn't think there's a clear line between human and AI. In the movie, obviously, after breaking the ice, he treats the Ava just like his girlfriend, he trusts her completely and finally being used by Ava. Two main characters of AI, Ava and Kilko. As the boss says in the end of the story, Ava is to designed to escape by using her all abilities: language, sexual attraction, sympathy even lies. It turns out she pasts the Turing past, even better than the expectation of the boss. Thanks to the director who didn't make a happy ending which would make this great movie into a piece of "lovely" sh*t. So in the opposite way, this AI Ava doesn't fall in love with our poor hero which can be seen as she doesn't have love, she just has the ability to pretend to love. I think, it leaves a question for us the audience " Do you think Ava passed the Turing test? or "Do you think an AI can pass the Turing test without having love. Another AI is Kilko, who I think, is designed to be a partner with sexual ability, although she can't talk. Due to the character of the boss, he is so proud that he might think he's a God, so for him, the best partner is one who can completely follow his order and provide all he needs, such as food, cleanness, sex. In the end of the movie, Kilko put the knife into his body, which is an evidence of the failure of making such an ideal AI partner. In a summary, I'd like to say, it's a fantastic movie with all ingredients in the field of AI and the director and his crew made all the ingredients into a concise but thoughtful movies. My sincere respect for this movie and its makers.
