Genetic manipulation of our genome is the next logical step. We're like ***this*** far away as it is. It will start the way all medical things start: treating really dreadful, disfiguring ailments (those that it can address). Then the technology will be made available for the really bothersome
things. Then the irritating
things. Then it will go on to small enhancements
that are considered generally acceptable. Then the lid will come off.
This is how pretty much every medical technology basically: pioneering advances just on the fringe of technology made available to those desperately in need. Then people become comfortable with it and the comfort grows incrementally over time until it's a part of every day life.See question on Quora
