BTW...I don't have anything against genetic engineering of humans as a concept...
Just of the idea of some authority deciding that there is an "ideal" human, and forcing a single mold on humanity.
When I thought about it some more, if genetic engineering became a commodity, for people to choose on their own ("choose" being the key), we might have countless varieties of humanity some day. Each person could seek their own idea of what an improved human being should be, without forcing it on anyone else.
The result might be marvelous, and with many different solutions, the variety needed for the health of the species would still be preserved.
