Chinese Scientists Try Gene Editing On Human Embryos

Chinese scientists used the CRISPR-CAS9 genetic editing tools to genetically edit human embryos. No, they did not implant the embryos in human wombs. They did not even start with embryos viable enough for implantation. The goal was to genetically test the results and measure the accuracy of the genetic edits. The scientists found the genetic editing was not precise enough. Not all embryos got the desired modification. Some got undesired genetic mods. The tech is not mature enough. Will improved CRISPR-CAS9 techniques eventually become viable or will other approaches be necessary? Some American scientists want a moratorium on attempts genetically alter germ line (egg, sperm, embryo) DNA. But I do not see a problem with using left-over embryos from fertility...
