The main reason why "Dolly" caused a sensation in the world was not the eloquent comments of scientists. The public's interest in Dolly is not about the scientific value of artificially manufactured all-powerful stem cells. What the public cares most about is human beings themselves. If they can make sheep's all-powerful stem cells, wouldn't they also make human all-powerful stem cells? If so, couples who have lost their children can use their children's somatic cells to create all-powerful stem cells to "regenerate" the dead children. In addition, if someone's totipotent stem cells are artificially manufactured and frozen after they develop into a young embryo, once one of the person's organs breaks down, the organs obtained from the embryo can be used to install them on the person. Human longevity seems to have become easier to achieve.
However, when it comes to making human all-powerful stem cells, some ethicists and national politicians become worried. If human totipotent stem cells are also produced by mixed cells like sheep, then since the people developed from totipotent stem cells are basically similar to the individuals supplying the nucleus, what should the relationship be between the people bred from these totipotent stem cells and the individuals supplying the nucleus? Parent-child, or identical multiple births? Doesn't seem to be quite so. Because the cytoplasm is not the same, even if we admit that they are barely counted as identical multiple twins, there is still an age gap between the same generations, posing a difficult problem for ethics. The people born in this way not only confuse the concept of generation, but also cannot be determined in the legal inheritance relationship. Secondly, this technology may be abused by some scientific maniacs, who will take the opportunity to launch a new eugenics movement, trying to use all-powerful stem cells to reproduce "geniuses." There may also be people who may further mix human cells with monkey or pig egg cells in an attempt to cultivate human-monkey or human-pig hybrids, which will deal a heavy blow to human society. Therefore, the dream of "immortality" by making mixed cells cannot be realized. We should make good use of this technology to contribute to the scientific development of mankind.
