This movie illustrates one of the big fears surrounding A.I. in general, namely what will happen once the computers start to think for themselves instead of being controlled by humans. The fear is valid: we are already working with machine learning constructs called neural networks whose structures are based on the neurons in the human brain.
With neural nets, the data is fed in and then processed through a vastly complex network of interconnected points that build connections between concepts in much the same way as associative human memory does. This means that computers are slowly starting to build up a library of not just patterns, but also concepts which ultimately lead to the basic foundations of understanding instead of just recognition.
