Why do few people talk about cloning now?

The technology of cloning was still very popular a few years ago, because there were many posts on the island discussing cloning at that time. For example, Dolly, the earliest cloned sheep, people thought that people seemed to have found a technology that could make people live forever, because cloning an identical person could transplant the corresponding organs to another person and realize immortality.

Now we seldom see the corresponding topic of cloning, because people have seen some defects from Dolly Klingen, which proves that cloning technology is far from practical application, and it is too intelligent, because people have seen pictures of damaged genes in Dolly the cloned sheep and her own physiological defects caused by asexual reproduction, because Dolly the cloned sheep only lived for six years, and with the efforts of scientists, she was still a normal sheep.

Cloning biotechnology can only be said to have entered a normal development stage. As for the extent to which it has entered, no one knows, because many scientific research achievements will not be released to the public unless they produce any visual results. Maybe all this is going on quietly now, and cloning it seems to involve some ethical issues. Because an identical person has been cloned, which one of them should enjoy normal human rights in society. Who should serve whom is a problem, because the clone has a complete mind and looks exactly like another person.

Generally speaking, the current cloning technology is not mature enough. If we clone some cell groups, such as organs cultured from skin, it is still difficult, but it is very difficult to cultivate an identical person, because he may have various genetic mutations, just like the process of transferring data from a U disk to a computer, resulting in the loss of data. Although most of them have been passed, some data will be lost.
