Digital immortality (or "virtual immortality") is the hypothetical concept of storing (or transferring) a person's personality in more durable media, i.e., a computer, and allowing it to communicate with people in the future. The result might look like an avatar behaving, reacting, and thinking like a person on the basis of that person's digital archive. After the death of the individual, this avatar could remain static or continue to learn and develop autonomously.
A considerable portion of transhumanists and singularitarians place great hope into the belief that they may become immortal by the year 2045, by creating one or many non-biological functional copies of their brains, thereby leaving their "biological shell". These copies may then "live eternally" in a version of digital "heaven" or paradise.
The realism of the concept
The National Science Foundation has awarded a half-million-dollar grant to the universities of Central Florida at Orlando and Illinois at Chicago to explore how researchers might use artificial intelligence, archiving, and computer imaging to create convincing, digital versions of real people, a possible first step toward virtual immortality.
The Digital Immortality Institute explores three factors necessary for digital immortality. First, at whatever level of implementation, avatars require guaranteed Internet accessibility. Next, avatars must be what users specify, and they must remain so. Finally, future representations must be secured before the living users are no more.
The aim of Dmitry Itskov's 2045 Initiative is to "create technologies enabling the transfer of an individual’s personality to a non-biological carrier, and extending existence, including to the point of immortality".
Reaching digital immortality is a two-step process:
- archiving and digitizing people,
- making the avatar live
Archiving and digitizing people
According to Gordon Bell and Jim Gray from Microsoft Research, retaining every conversation that a person has ever heard is already realistic: it needs less than a terabyte of storage (for adequate quality). The speech or text recognition technologies are one of the biggest challenges of the concept.
A second possibility would be to archive and analyze social Internet use to map the personality of people. By analyzing social Internet use during 50 years, it would be possible to model a society's culture, a society's way of thinking, and a society's interests.
Rothblatt envisions the creation of "mindfiles" – collections of data from all kinds of sources, including the photos we upload to Facebook, the discussions and opinions we share on forums or blogs, and other social media interactions that reflect our life experiences and our unique self.
Richard Grandmorin summarized the concept of digital immortality by the following equation: "semantic analysis + social internet use + Artificial Intelligence = immortality".
Susanne Asche states:
|“||As a hopefully minimalistic definition then, digital immortality can be roughly considered as involving a person-centric repository containing a copy of everything that a person sees, hears, says, or engenders over his or her lifespan, including photographs, videos, audio recordings, movies, television shows, music albums/CDs, newspapers, documents, diaries and journals, interviews, meetings, love letters, notes, papers, art pieces, and so on, and so on; and if not everything, then at least as much as the person has and takes the time and trouble to include. The person’s personality, emotion profiles, thoughts, beliefs, and appearance are also captured and integrated into an artificially intelligent, interactive, con-versational agent/avatar. This avatar is placed in charge of (and perhaps "equated" with) the collected material in the repository so that the agent can present the illusion of having the factual memories, thoughts, and beliefs of the person him/herself.||”|

Making the avatar alive
Defining the avatar to be alive allows it to communicate with the future in the sense that it continues to learn, evolve and interact with people, if they still exist. Technically, the operation exists to implement an artificial intelligence system to the avatar. This artificial intelligence system is then assumed to think and will react on the base of the archive.
Rothblatt proposes the term "mindware" for software that is being developed with the goal of generating conscious AIs. Such software would read a persons' "mindfile" to generate a "mindclone". Rothblatt also proposes a certain level of governmental approval for mindware, like an FDA certification, to ensure that the resulting mindclones are well made.
During the calibration process, the biological people are living at the same time as their artifact in silicon. The artifact in silicon is calibrated to be as close as possible to the person in question. During this process ongoing updates, bug fixes, synchronization, and interaction between the two minds would maintain the twin minds as one.
