Like with most technologies of this sort, I think it's often a matter of how well does it work. But is it even ethical here to attempt to develop this? How many failed attempts does it take to refine it? If the tech can magically spawn of nowhere and create totally healthy at birth and later in life children, I'm sure people will get used to the idea of it. But the path to get there seems unethical.
