CRISPR in China

Chinese scientists are working to manipulate the DNA of human embryos in a laboratory.  The process is call CRISPR, which edits the embryo’s genes during in vitro fertilization.  It’s unclear if they’ve been successful yet.  The claim of course is to eliminate hereditary diseases by removing the genes responsible for them.  The concern is if problems arise, they’ll be replicated in that child’s future children, grandchildren and beyond.  It’ll only be a matter of time before they try producing designer children with higher IQs and other features not related to health.  Individuals with Down syndrome, who richly contribute to society would of course be targeted.  This is akin to playing with matches, unconcerned about the ethics or potential disasters involved.
