With the development of medicine, the comparison is no longer the enjoyment of age, but the enjoyment of quality of life and value creation. Humans are progressing, that's for sure, no matter how advanced medicine is and how long people can live, it will always be the quality genes that are in control of the whole world. Because everyone needs to create value and then get the fruits of their labor in the form of money, and then use the money from their labor for a better quality of life and a longer lifespan. If we think about this issue only from the degree of genes, the value created by individuals carrying inferior genes cannot surpass that of individuals carrying superior genes, so a relatively stable social pattern is formed, i.e., individuals carrying superior genes are the ruling class, enjoying the fruits of labor of the whole human race, and individuals carrying inferior genes are the dominated class, used to create value for individuals carrying superior genes in the most basic way without any technological content. technical value. So even if an idiot (and I don't mean you) lives to be 100 years old, he is nothing more than an appendage of the individual who carries the superior genes, a primitive laborer to be extracted from the value of his labor.
The above points are only considered from the standpoint of genes, and the social element is completely excluded from consideration.
