A young programmer is selected to participate in a ground-breaking experiment in artificial intelligence by evaluating the human qualities of a breath-taking female A.I.

Nathan: One day the AIs are going to look back on us the same way we look at fossil skeletons on the plains of Africa. An upright ape living in dust with crude language and tools, all set for extinction.
Ava: Isn't it strange, to create something that hates you?
Nathan: C'mon buddy. After a long day of Turing tests you gotta unwind.
Caleb: What were you doing with Ava?
Nathan: What?
Caleb: You tore up her picture.
Nathan: I'm gonna tear up the f*in' dance floor, dude. Check it out.
Caleb: Did you program her to flirt with me?
Nathan: If I did, would that be cheating?
Caleb: Wouldn't it?
Nathan: Caleb, what's your type?
Caleb: Of girl?
Nathan: No, salad dressing. Yeah, of girl; what's your type of girl? You know what, don't even answer that. Let's say its black chicks. Okay, that's your thing. For the sake of argument, that's your thing, okay? Why is that your thing? Because you did a detailed analysis of all racial types and you cross-referenced that analysis with a points-based system? No! You're just attracted to black chicks. A consequence of accumulated external stimuli that you probably didn't even register as they registered with you.
Caleb: Did you program her to like me, or not?
Nathan: I programmed her to be heterosexual, just like you were programmed to be heterosexual.
Caleb: Nobody programmed me to be straight.
Nathan: You decided to be straight? Please! Of course you were programmed, by nature or nurture or both and to be honest, Caleb, you're starting to annoy me now because this is your insecurity talking, this is not your intellect.
Caleb: [Quoting J. Robert Oppenheimer who cites the Hindu Gita] "I am become death, The Destroyer of Worlds."
Caleb: [from trailer, talking about ending the project] It's not up to me...
Ava: Why is it up to anyone?
Nathan: You know this guy, right? - Jackson Pollock. - Jackson Pollock. That's right. The drip painter. Okay. He let his mind go blank, and his hand go where it wanted. Not deliberate, not random. Some place in between. They called it automatic art. Let's make this like Star Trek, okay? Engage intellect.
Caleb: Excuse me?
Nathan: I'm Kirk. Your head's the warp drive. Engage intellect. What if Pollock had reversed the challenge. What if instead of making art without thinking, he said, "You know what? I can't paint anything, unless I know exactly why I'm doing it." What would have happened?
Caleb: He never would have made a single mark.
Nathan: Yes! You see, there's my guy, there's my buddy, who thinks before he opens his mouth. He never would have made a single mark.
Nathan: The challenge is not to act automatically. It's to find an action that is not automatic. From painting, to breathing, to talking, to fucking. To falling in love...
Nathan: And for the record, Ava's not pretending to like you. And her flirting isn't an algorithm to fake you out. You're the first man she's met that isn't me. And I'm like her dad, right? Can you blame her for getting a crush on you?
Nathan: [speaking about Ava's brain] Impulse. Response. Fluid. Imperfect. Patterned. Chaotic.
Nathan: Caleb, what's your type?
Caleb: Of girl?
Nathan: No, salad dressing!
Nathan: It's funny. You know. No matter how rich you get, shit goes wrong. You can't insulate yourself from it. I used to think it was death and taxes you couldn't avoid, but it's actually death and shit.
Caleb: You hacked the world's cell phones?
Nathan: Yeah. And all the manufacturers knew I was doing it, too. But they couldn't accuse me without admitting they were doing it themselves.
Nathan: I am God
Nathan: The good deeds a man has done defends him. The good deeds a man has done defends him. The good deeds a man has done... defends him.
Caleb: It's obvious, once I stop to think.
Ava: Hello.
Caleb: Hi. I'm Caleb.
Ava: Hello Caleb.
Caleb: Do you have a name?
Ava: Yes. Ava.
Caleb: I'm pleased to meet you Ava.
Ava: I'm pleased to meet you too.
Nathan: There you go again. Mr Quoteable
Nathan: Okay. Fucking unreal. Okay. Ava...
Ava: Will you stay here?
Caleb: Stay here? AVA!
Caleb: We need to talk about the lies you've been spinning me.
Nathan: What lies?
Caleb: ...Why me?
Nathan: It is what it is... It's Promethean man.
[first lines]
Caleb: How long until we get to his estate?
Pilot: [laughs] We've been flying over his estate for the past 2 hours.
Nathan: Over the next few days you're going to be the human component in a Turing test.
Caleb: Holy shit!
Nathan: Yeah, that's right, Caleb. You got it. Because if the test is passed, you are dead center of the greatest scientific event in the history of man.
Caleb: If you've created a conscious machine, it's not the history of man. That's the history of gods.
Nathan: This isn't a house, it's a research facility.
Caleb: Some people believe language exists from birth. And what is learned is the ability to attach words and structure to the latent ability.
