&gt;The most likely approaches for increasing the intelligence <i>of humans</i><p>I agree, given the gestation time of a human, AI may well come first. Even if we perfected iterated embryo selection today, 18 years is a lot of time and perhaps AI would be developed before the super geniuses reach peak productivity.<p>&gt;Also I don&#x27;t think there&#x27;s an iq 200 set of genes, there&#x27;s probably trade offs that would prevent this a brain has a given number of neurons and they operate at a slow speed so this is like trying to breed a better horse when cars are obviously on the horizon and will be followed by jets.<p>Everything I&#x27;m reading is saying the genes for IQ, as with most traits, are additive. And it really is as easy as putting as many high-IQ-associated genes into one genome as possible.
