Will we ever defeat death? This is the riddle of immortality.

I don't think it will be possible to defeat death. Perhaps with the development of technology and knowledge about the brain, it will be possible to transform human consciousness in such a way as to transfer it to something based on artificial intelligence, so as to preserve this consciousness and further develop it. It is true that now it sounds like a complete abstraction that has no right to come true, perhaps one day such a time will come, but in our lifetime it is simply impossible.

The physical body dies, at the moment it is insurmountable. We are not the body, so it doesn't matter. The spirit is immortal 🙂

If we became immortal, what would it be like if the earth crumbled

I recommend the book by Harari, advisor to K. Shwab, who claims that immortality may be available around 2100, but only for the elite
