What would society look like if humans achieved immortality?

I think that if we humans can live forever, our world must be particularly beautiful and we can all survive in peaceful times, because none of us humans can live forever, except for those who are particularly kind and insist on positive energy. You still need a lot of principles and wisdom to achieve immortality, but most people in the world are working hard day and night for their own interests. They are overworked, tired, running around, and are tired of all kinds of diseases. In addition, we humans have destroyed many natural things for our own interests. The environment has been destroyed, causing many disasters to attack mankind. Many people in the world suffer from various diseases and too many people die in disasters. If you really want to achieve immortality, you must be equipped with many truths about life. Only then can you live forever in this world. But no one dares to say that they can live forever in this world. Even I can’t guarantee that I can live forever. Everyone in the world wants to live forever. As of now, no one can achieve this kind of longevity. There may be some in the future. Immortality depends on fate. This is my opinion.
