Rather, its possible that even the smarter ones will suffer at the hands of the stupid, because of the social order we live in.
However, I still believe natural selection still goes on, in a different way. We're becoming social after all, no longer competing for biological requirements, but social ones.
More so when you consider that smart ones will know that if they can't afford children, they won't have children (or limit the number) while douchebags and idiots wouldn't really give a hoot how many paternity suits they're getting served with. You can see that in elections - in the Philippines, there are too many people who think in this pattern: "Government can't take away my right to sexy times with my (ugly) spouse! Free condoms are repressive, Big Brother government tactics,* and our Parish Priest concurs that they are EVIL!!! I can't feed my children let alone pay for college, and it's totally the government's fault! I'll vote for that guy and his entire family running for every position and Congress seat because 1) the Bishops said so and 2) they dole out money for our needs!**"
Here's the other sad part of how technology could have, but fails, to develop humanity as a whole. In a time when you can Google pretty much anything and Wikipedia info is actually good enough but just not for citing Wikipedia itself for an academic paper, I keep on running into people (like my cousin) who has no freakin' idea about anything. Yes, there are a lot of people learning through the internet, like schools in some mountain village getting satellite internet faster than my broadband at home (and they're using it to access documentaries and the like, while I'm using mine for Steam), but I can't shake off the fear that they'll still be outnumbered by the YOLO crowd.
*Reality check - a real Big Brother, weiwen, or whatever term you'd call it would be me neutering every unemployed schmuck with at least one kid. If I can do that to my tomcats who I love, having it done to idiots that annoy me won't bother me at all.
**They get it out of Pork Barrel which, surprise!, comes out of tax payers' money and instead of renovating public hospitals or getting them better equipment, paying the staff more particularly when they stay at work on New Year's Eve instead of eating roast with their own families because these squatters have ridiculous amounts of money for firecrackers and liquor but not for private hospitals, they use it to give scraps to lots of people who will vote for them not realizing society would benefit better from proper infrastructure, schools, and hospitals. Based on the current figures of the pork barrel scams, apparently we shouldn't be far behind Cuba's health care quality thanks to all the uptake from a Capitalist economy. Instead these blood sucking kulaks are draining us dry.
