Digital immortality refers to the idea that a human mind, consciousness, or mental information such as memory, personality, and intelligence can be transferred to or duplicated in digital media so that it continues to exist after the death of the body. In the context of mind uploading, it is the promise that a person could survive bodily death by having their mental patterns preserved and re-instantiated in a computer, a new body, or a virtual environment.
According to the provided context, this is still a theoretical concept and has not been realized experimentally. Its intellectual background spans a wide range of traditions, including ancient debates on soul and body, later mechanistic views of the human being, cybernetics, and transhumanist thought. The concept also appears early in science fiction. Arthur C. Clarke’s The City and the Stars (1956) is described as a pioneering work in which citizens of Diaspar live in cloned bodies and, when those bodies expire, their personalities are stored as information patterns in the city’s central computer and later imprinted into new clones.
The context also emphasizes major criticisms. The central philosophical issue is personal identity: if a digital copy contains one’s memories and character, is it really the same person, or only a duplicate? Other concerns include inequality in access, the possibility of modification or copying of digital persons, and legal and social disruption. For this reason, digital immortality is presented less as a solved technology than as a powerful framework for asking what counts as a human being and what counts as a mind.
