I think the idea of people with higher IQ's reproducing does not have a definite outcome.
Throughout the history there were smart people that accomplished a ton and never had kids. I always ask, is it because they were smart and gifted or is it because they put their efforts towards what they were doing and not towards raising the kids?
I gather that Jesus Christ did not have any kids. This explains why he could go around, preach the word and spend his energy and dedication on other people, who were not his children.
I am thinking, based on my observations, that only about 30% of couples out there are worthwhile of parenting. There are plenty of things the rest of people can do. They can start looking for a cancer cure for starters.
Parenting job is by all means not for everyone. Like I said, I only see about 30% of people who have kids who are actually good parents. The rest are just there for whatever other reason they may choose as an excuse that usually does not make any sense.
If only 30% of people did have kids, I think we would be a much more advanced and better society. Gangs, crime, and terminal illness would be less common. We would look for more robot technology. Our water would be cleaner. And for me, I would remain in the 70% of folks who do not parent and do some kind of scientific research to help future generations. Today, as we stand, we waste so much time and energy on pro-creation that we forget about the Earth, space and future. We always think "someone" will find cure for cancer. "Someone" will battle other terminal illnesses. We are so hung up on having kids, we are actually rolling backwards. Many science and research projects in Universities are being eliminated and replaced with business and investment courses due to lack of interest. No one wants do do anything unless there is an instant gratification. That seems rational, but only for a short term. Who is going to research and develop stuff that has no instant payoff and quick reaches. We are set and trained to provide to the public what it wants this second and time. We want to make an instant dollar.
One example is housing. For every 100 housing investors, there, at the most, 1 person who is caring enough to research a more energy efficient building and development.
To show how ass backwards our society is, I will describe another example. Let's say I have a medical research project that I'm trying to put together that concentrates on full lifelong functionality. This would allow old persons to live to the last day, and fully support themselves. I probably would get a few interested investors, but only a few. Now, if, for example, I was working on a IVF system that allowed 70 year olds to get pregnant and deliver a baby, I cannot tell you how much investment I would get. I bet, I would get so much money, I would not know what to do with it. This really shows how little people think and how much "thinking" is done at the Hollywood, how much influence that movie industry has.
