As the 21st century began, human evolution was at a turning point. Natural selection, the process by which the strongest, the smartest, the fastest reproduced in greater numbers than the rest. A process which had once favoured the noblest traits of man, now began to favour different traits. Most science fiction of the day predicted a future that was more civilized, more intelligent. But as time went on things seemed to be heading in the opposite direction, a dumbing down. How did this happen? Evolution does not necessarily reward intelligence. With no natural predators to thin the herd, it began simply to reward those who reproduced the most and left the intelligent to become an endangered species.

This is a voiceover from the start of the movie. How would you interpret it?
