If this technology gets to the secret services or terrorists, it could have very serious consequences. Why geneticists have banned the experiments on human beings? Because technology allows us to artificially raise soldiers. I think you need to ban this technology for the same reason.
Tech like this will arrive at some point. It won't be possible to uninvent it either. Never in human history has everyone agreed to not research and create something potentially advantageous. Someone, somewhere will do it.
