I don't consider their fundamental premise sound, that if the poor countries are fecund and the rich countries are not, that it will automatically lead to the end of worldwide technological innovation. As I see things, it's a fact that, 1.) Immigration exists and is good, and 2.) it doesn't take very many years of education to turn someone from a disadvantaged background into a scientifically savvy modern person. If the author of this article merely forgot that, then that's quite an oversight. But you're right, it was uncharitable of me to assume he didn't forget, and actually thinks that either 1) or 2) are false. So I retract my cynicism and replace it with constructive criticism.
