According to the British "New Scientist" magazine, Zoe Graystone is a girl with two brains. One is a human brain and the other is a precise digital backup that has its own consciousness. After Graystone's death, scientists transplanted the "digital brain" into a humanoid robot. Although the "flesh" is no longer the past Graystone, it has saved her from the "grave". Will such a scene become a reality? How far is the true incarnation from us? Upload your life and achieve immortality by backing up the brain. For decades, science fiction movies have been filled with these strange concepts.
