Designer babies is the start. Like I already believe if you're "selecting" something like your baby's gender, you're fuckin Hitler. But then, my roommate was all, "Well what if you could remove the trait for Huntington's that runs in the family?"
So there's clearly a spectrum of ways that genetic engineering could go.
The most interesting case to me is of He Jianku, who reportedly began studying and modifying human embryos. CIA fear disinfo, or Chinese scientists just marching ahead and setting the new standards of the 21st century?
It'd be cool to eliminate diseases passed down genetically, but it could take a nose dive into fascist territory real quick. See: Nazis scapegoating Jews on the grounds of eugenics.
Nose dive? This idiot is already talking serious fash shit about "curing" autism. Also, eugenics in practice always works well for the rich and is genocidal for the poor.
