I agree that the overall premise is somewhat eugenics-y, but I overlook that on the basis that it's a comedy movie from 2005 and it's easier to swallow than something like "aliens abducted all the world's smart people"[0] or something. There are still some good themes on over-reliance on automation without understanding it.
The Idiocracy line that I think about the most these days is "Brawndo stock dropped to zero and the computer did that auto-layoff thing to everybody."
