What if life could be eternal? I was inspired by the movie Swan Elegy. An agency copied the hero into an exact version of himself. Can people's lives be "copied" and "pasted" through the preservation of human memory? The storage function of DNA is very good for preserving people's memories. Just like the cloned sheep Dolly, can people also complete the eternity of life through this form of replication? AI technology is becoming more and more powerful, and many imaginary things can be realized in the future. Whether DNA is in the form of particles or digital information, and whether the memory of DNA is added to the robot or the memory of life before is stored in the information, human beings may indeed be able to have a "second life" in the future.
