What would it achieve? Even if I wrote above that IQ is important, it is evident that those of the highest intelligence often suffered greatly in life. Let alone true geniuses. Schopenhauer, again, wrote brilliantly about it.
It is more likely that man would not be able to use this technology wisely, just as he does not use our current technology wisely either. And will result in even more damage being done. See also Stefan Molyneux and Michael Woodley of Menie: Why Civilizations Rise and Fall (around the end Dr. Woodley talks about genetic engineering and related technology.) Dr. Woodley also has a book out—that I have not read—with Edward Dutton called At our Wits’ End: Why We’re Becoming Less Intelligent and What It Means For the Future.
Need to quote Don Colacho:
If man ever managed to fabricate a man, the enigma of man will not have been deciphered, but obscured.
Whoever does not turn his back on the contemporary world dishonors himself.
It is indecent, and even obscene, to speak to man of “progress,” when every path winds its way up between funerary cypresses.
