I believe that overpopulation is the most in-your-face example of the failure of modernity by far. I believe even morons can understand why. It is the wildest manifestation of the moderns' fixation with quantity not quality (in a universe that most clearly values quality more). In a functional universe like this, it is as if you're saying every personal computer has the same value. Well Mr Modern, even your capitalist system neglects this view. Pathetic.
Another thing about overpopulation is that it proves that technology (if it's gone too far) might become destructively dysgenic and apocalyptic. I don't know, maybe technology is not inherently bad, but there has to be a certain degree of genetic/cultural evolution of the life forms themselves before they are worthy of handling such a level of technology.
This is scary news. We need to explore space so we can find an alien life form and invite them over to our planet as immigrant workers. We need young people to take care of our elderly! And if there are no young people then we'll have to use aliens! I'm sure that if the aliens have a different culture we can just make some adjustments to accommodate them.
