Modern humankind has owned the self-body gene modification technology, but there are problems of correctness. For the meat without killing or the new organ part which is wanted to be installed on the body or work independently, outside the body, on the production line, it just be scrapped if there is something wrong; but for the self-body, no risk can be taken. In the future, the speed of correcting the incorrect gene modification will greatly reduce the risk, and what kind of world will be formed? Frequent gene changes make the gene code no longer valid for identity authentication, frequent body shape changes let external features not be used as a basis for identification, the rest is that the neural information group can be used as the basis for authenticating individuals. It's like many fake accounts on modern social networks, no matter whose image you've stolen, we always know who you are.
