I just came back from the film Limitless. The movie contained a very interesting depiction of a character who gets an black market nootropic that works very well. It gives him perfect recall, perfect situational awareness, and the ability to figure out the best thing to say/do in real time. He uses this new power to finish his book, get back together with his girlfriend, become rich, and eventually become president of the united states. Incidentally he gets in shape, establishes himself as high status at top tier social events, learns many new languages, and sleeps with a bunch of women. In the end his new found intelligence leads him to happiness. The drama in the film comes from the fact that the drug has side effects, and there's a mobster who gets his hands on some and wants more. Intelligence is depicted as a fundamentally good thing. It's even described as "I knew what I wanted and I knew how to get it." He affirms several times (and the story agrees) that he's still himself on the drug, just more effective.
