Limitless

I saw the movie LIMITLESS last week. It really made me think about "what if people could just take a pill and be able to access all areas of their brain?" What kind of world would this be if everyone simply took pills and had unlimited knowledge? Everyone would be good at everything and then how corrupt would people become? Would it even seem corrupt or would it just seem normal if everyone took the pill? I wonder if one day there really will be some sort of medication that made you smart or really good at something you always wanted to do? If anything was attainable, how many people would choose to take the pill and "choose which life they wanted". You can basically live whatever life you wanted. Is this our future or just a crazy idea for a movie?
