No, blondes will not die out in 2 centuries

Many popular articles about future evolutionary trends of the human race are as naive as science fiction show that portray humans in future centuries not much changed from what they like now. A recent example of this is a new study that claims blondes will disappear within 2 centuries:

A study by experts in Germany suggests people with blonde hair are an endangered species and will become extinct by 2202.

Researchers predict the last truly natural blonde will be born in Finland - the country with the highest proportion of blondes.

The argument is that since blondeness is a recessive gene and fairly rare in the total human population as more people breed with people from other parts of the world the odds of two people giving their offspring blonde genes will go down. Plus, there is an added argument that real blondes are not breeding as rapidly as the rest of the human populace.

The problem with any such argument is that it ignores the coming ability of people to control what genes they give their offspring. Once genetic engineering of offspring becomes possible the number of blondes will increase for the simple reason that many women who now dye their hair blonde will want their daughters to have the benefit of genetically based blondeness. So I expect the number of blondes to start dramatically increasing within 30 years.

When regular sex becomes used only for recreation and offspring are genetically engineered each new generation of the human race will look like what the previous generation held as ideal. Since blondeness is extremely popular expect future generations become more blonde than ever.
