In our short decades, we don't know what we are doing. If there is infinite life, it will be a kind of sorrow. As Taoism says, "When you are alive, who knows that living will not make people regret it?" When you are alive, who knows that life is not like a wanderer? "Living is not necessarily better than dying. Before these problems are clarified, there is no need to make people immortal, because it may also be "eternal death." "

Let's talk about feasibility first

There are many schemes. Technically speaking, it is not difficult for us to make a person live forever. However, considering the special sociality of human beings, "immortal people" did not appear in front of us. The landlord believes that immortality is not just about keeping one's thoughts uninterrupted (reasonable sleep is not a choice). So we can clone people and take out the cloned brain. Brain transplantation before death. I don't know if my brain will stop thinking after leaving my body, but I can still keep my personal thoughts unchanged and continuous after transplantation. The brain will eventually die, and we can do brain cutting in this respect. Cultivate brain cells in equal parts and replace them partially when the brain is "old". Suppose the brain is divided into 100 parts, and it is completed after each replacement of 1 part and 100 times. This can ensure the continuity of the brain. Unlike cloning, ideas change. Of course, the combination of partial brain replacement and partial amnesia will also leave a deep impression on individual thoughts. But I think this kind of flaw is acceptable.

From the perspective of sustainable development.

If the whole people live forever, there will be insufficient housing, energy and food. It is necessary to develop aliens in this way. We can transform a large number of cloned creatures into them, create aliens, and move them when they are in line with human survival. But on the whole, the universe will die. True immortality is not feasible. But this is essentially different from the natural death of human beings, so you can choose eternal life.

To sum up, human beings need a lot of money and technology to realize individual immortality. It's not feasible at this stage, so it's hard to say in the future. However, people have different views on whether human beings should be regarded as immortals. Some people think it's good to live forever, while others think that normal family inheritance is good. This is not a contradiction. We can even stipulate that those who accept eternal life can't have children, and those who don't accept eternal life can continue to live as they do now. This not only enriches people's world outlook, but also greatly stimulates science and technology.

Immortality is feasible, but not necessary.

PS: I personally want to live forever and find out the reason to live.
