This isn't a religious thread. Don't make it into one.
I really don't think people are confined within Darwinism any more (survival of the fittest). You see, all the lower denominations in terms of broad species survival like suicidal folk and mentally retarded people (real ones) don't get much opportunity to spread their genes as compared to other people. Sure, they might spring a kid or two before whatever happens to them and they don't matter any more, but generally speaking, their reproductive abilities are not quite up there.
Then there's all the high value individuals like geniuses and world-class sportsmen. These guys, generally speaking, either have children or have very few children for various obvious reasons. In fact, I'm pretty sure most Bay12 members don't want to have more than 3 children either if any at all.
So, what are we left with? We are left with the mass majority of common, average, mediocre people. It doesn't really matter who they are, be it the cubicle man or the trailer family, the end result is that these people make up the vast sum of our population. Neither spectacularly good or bad at anything. This is further examplified by the fact that most of our newborn children come from this subgroup. Even if we say that 1 out of 3 children born out of an "average" family will be "non-average", the end result is that the grand majority of our population will be average.
We are headed in the direction of average... I couldn't say when we started heading in that direction, when being average meant being the strongest of our race, but it really is depressing. It also seems that we spread this trait to everything we associate with life, like pets. Cats no longer live on a principle of the fittest survive, but rather, the cutest or whichever gets along with humans the best. Goldfish have been that way for centuries now, thanks to the Chinese.
What do you think? Is this a good thing? A bad thing? I'm quite on the fence.
Keep in mind that it doesn't mean humankind won't progress. It just means that we'll progress by taking the mean of all our achievements and failures instead of just the achievements.
tl;dr: Reading is a very important skill in life.
