Human germline editing is a complex issue. It has been argued that it could help to prevent genetic diseases. While this could be true, it is uncertan whether this could become a universal tool for genetic illness prevention, or rather a new and sophisticated privilige for rich. Furthermore, recently, a chinese scientist edit babies that were going to inherit AIDS. The edition appears to succesfully confer them immunity. Nevertheless further inquiry revelaed that genes related with neurological function were also altered. It is not clear if this was done in purpose, or was a collateral effect, albeit some experts take this as a try to improve human innate neurological resources. All in all, CRISPR-Cas9 editing application in humans is still in its infancy, and strong regulatory rules must be designed to properly employ it.
