Not being able to code will be, in 10 years, like not being able to parallel park. People will look at you like, "Really?"
I suspect in 10 years at least, things will go similarly for programming. But maybe in 30,40,50 years; better diets,better environments, nutritional junk food, better education, designer children, gene therapy, drugs, implants, whatever will push mean IQ out of its current local maximum.
