I find the argument fairly weak for a number of reasons. Iodine supplementation seems to have worked great
Iodine supplementation isn’t enhancement; it’s more like fixing a broken component. If a machine has a broken part, fixing it might dramatically raise the performance of the machine, but that doesn’t tell you how easy it would be to improve a machine with no broken parts.
That mostly seems to be semantics to me. There could be other things that we are currently “deficient” in and we could figure that out by doing cognitive enhancement research.
As far as I know, the term “cognitive enhancement” is often used in the sense that I used it here, e.g. relating to exercise (we are currently deficient in exercise compared to our ancestors), taking melatonin (we are deficient in melatonin compared to our ancestors), and so on...
