There was a movie about humans who plug this small computer like device into their bodies (I think back of head or in upper back) and they become efficient and super intelligent but they lose their emotions and then become “bad guys”. Well, the main character becomes one of them by plugging this small device into himself and can track them because he becomes as smart as them. Well, soon later, he takes the device out and starts to be human again and have feelings. This movie was came out in the last few years, I believe. Please help me!!! I’m going crazy over here trying to figure out what the movie is called.
