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.
How would it work if everyone had this power?
Doesn't being rich require that others be poor?
Only one person can become president at a time.
Doesn't being at the top tier of social events (or anything) mean that there needs to be sub tiers?
"Sleeps with a bunch of women": this seems to answer the above problems. Humans would be so busy "sleeping" with each other they'd have little time or use for money, politics, or meaningless social gatherings. Food would still be important. I'd like to think art would be too. Sex, food, and transformative experiences. A return to the animal kingdom. That makes me almost hopeful.
But, I have this all wrong, don't I. I'm going back to the sequences now....
There is a moment where he gets "the idea". This is the thing that takes him from his hedonic whirlwind to a purposeful existence. He's trying to change the world.
My hope is that he'd use the powers of the pill to set up labs to study the process it works on, mass produce it, use his political clout as president to push it though as a legal nootropic, and use the bully pulpit to promote it. Make everyone smart.
