I am certain this is nothing new. Being that it is being reported by the mainstream media, and that I am certain the Chinese are not alone in this endeavor, then I am remiss is I do not state that it is the pot calling the kettle black.
Moreover, this scares me. It reminds me of the movie
Gattaca, where future mankind populations are controlled at the cellular stage... no chance for dissenters as far as we know.
I guess, were it to come to that, and people were merely drones and upper classes, then I would have to place my hope in the things which DNA modifications could not predict, and that being the human spirit and will.
At the end of the day, were this to be true, then we would certainly find out if we are nothing more than mere machines, and that there are no divine forces outside of us having a hand in our character make-up, and that there is a great beyond.
