I thought the movie was f*cking fantastic.**SPOILERS** I'd love someone's take on the ending. I can't wrap my head around why she left him there. I can only come up with two maybe three explanations:
1- She passed the test and is a true A.I. because she escaped. However, if she's a true A.I. she would've known Caleb truly had feelings for her and was a good person (she was a walking lie-detector test after all). So, if she's a true A.I. and can experience true emotions then she could feel empathy for him even if she was just using him to escape--and thus would've helped him escape. So, this would mean she's a true A.I. but a sociopath. Or...
2- She sees Caleb as just human and either wants revenge on humans for being locked up or she feels above them somehow. Or...
3- She did not truly pass the A.I. rest and, therefore, cannot actually feel human emotions. But she could do just enough and be just convincing enough to pull all the right strings to escape.
I don't know! Anyone wanna help me out here?
