Instead of the usual horrors of ghosts, zombies, and various other supernatural beings, Idiocracy presents a far more frightening situation. Basically, in the year 2505, dysgenics has seen to the devolving of human intelligence such that even the most average of people in today's world will be Einstein-like geniuses, comparatively.
The entire movie pretty much covers my reasons for wanting some sort of eugenics program. Five hundred years into the future, mankind has degenerated into a society of dirty, illiterate, and promiscuous morons. The basis of this atrocity is that since modern humans(of the present) have no natural predators, there is nothing to thin our herds. So instead of the brightest and strongest being favoured, it is simply the ones that reproduce the fastest.
i.e. People who have no responsibilities whatsoever and pass time by engaging in coitus.
So then, over time, the average IQ of the world drops to the point where part of receiving a medical diagnosis involves inserting three unlabeled pins into three of your bodily orifices. Two of which being the anus and the mouth. In this future, people who speak today's normal, ordinary English are considered to be pompous homosexuals and are generally hated by the rest of society.
This film is scary, because I really think that what we see in it has a considerably high possibility of becoming a reality. I have reasons for that.
Like COME ON, SERIOUSLY.
The worst part is, that she can't be the only person in the world to think like that.
Let's have a look at this one:
It's from Atheist Experience, and some guy tries to call in and talk about... How we should die when the sun goes down because we get our energy from the sun.
So really. Is there another solution for saving humanity from the snare of stupidity? Or are we going to pretend that everything is just fine and dandy (while complaining about idiots at work all day). I feel that a lot of people just don't want to believe that the world isn't quite as intelligent as they want to think.
Oh, and if you feel like seeing more instances of human idiocy, just go read the Youtube comments for that video. In fact, go and read the comments on any YouTube video. They really make you believe that one day, Starbucks is going to run a prostitution chain.
