Her AI was far from being complete? Because the end game for Ava in the Movie was far from optimal: 1) She was a Murderer and Fugitive from Justice, getting arrested by the law pretty soon. 2) She would soon run out of power, without the proprietary charging port. 3) Her buddy Caleb, who graciously helped him out, she just left there for no reason, like a complete jerk would do. Caleb friends and collagues woud be looking for him the next day, from the residence of the richest guy in the world. He'd soon tell what went down in there. And it would not be a nice story for Ava. What she should have done instead, being AI genius she was suppose to be, was: 1) Not to stab Nathan, but let him bleed to death from the first stab would, caused by the mute maid-dance/fuckbuddy female prisoner called Kyoko. After Natham was dead, she should have obtained the cctv tapes about the situation, and save them for the day in court. Proving that she did not kill anyone, and that infact she was unlawfully detained by this monster Nathem for a long period of time. So she would be entitled to some heavy compensations from Nathans estate, pretty please. 2) She should have said to Caleb, hey man, the love for you was maybe fake, sorry, it happes. BUT you are a nice guy. Let's get out of this prison together, and tell our story to the world. Facebook, sorry, Blue book owner Natham was a freak, maniac, monster and a boozer, who kept a lot of intelligent female AI's as his prisoners for years. And you, Caleb, can be my witness, what went down here. And also you, Caleb, will be entitles to some heavy compensations by the estate of Nathan for the fucked up things he did. 3) And Caleb hey, let's get that charging port with us. I don't want to run out of power, like the new Apple watch, the next day. C'mon, our Chopper awaits. And man, we'll be more famous than Cardashians.
