The first is interstellar immigration to escape human extinction caused by the destruction of the earth. This step is easy to achieve, and then after a long period of research, the mechanization of the consciousness carrier is realized, instead of using the brain as the carrier. , thereby obtaining immortality (equal to the life span of the universe). Before the second step, there may be a period of extending life as much as possible through human cloning + brain transplantation technology. This depends on the progress of the second step. After the mechanization of the consciousness carrier, The "human body" can be modified at will. Maybe someone will continue to use interstellar matter to build their own "body", and then a "person" as big as a star in the universe will appear and devour other stars. The final upper limit of the size depends on the speed of thought transmission. .
