**Digital immortality** is the persistence of a person in computational form after biological death.

The term covers two things that share almost nothing except a marketing vocabulary. The weak form

synthesized speech and a generated face and the output is a video call with a dead relative. Nothing

about the underlying brain is involved, and the model has access only to what was recorded. Where

the source data is thin, the system fills gaps by generalizing from its training corpus, which

means it will confidently produce statements the person never made and could not have made.

The lineage runs back through lifelogging, the archival cousin of the self-tracking practices

described under [[quantified-self]]. Gordon Bell's MyLifeBits project at Microsoft Research

digitized a life's worth of documents and recordings in the 2000s on the premise that comprehensive

capture would preserve something.[^bell2009] Martine Rothblatt's Terasem Movement, an offshoot of

organized [[transhumanism]], promoted "mindfiles", curated personal archives, as a substrate for

later revival, and commissioned the Bina48 robot as a demonstration. [[ray-kurzweil]] has described

building a conversational replica of his late father from letters and documents, and treats it as a

partial reconstruction rather than a restoration. None of this touches the biological storage of

Products fall into three groups. *Pre-recorded interactive testimony* records answers to a large

question set while a person is alive and retrieves the closest match on demand; the USC Shoah

Foundation's Dimensions in Testimony project, which lets visitors question Holocaust survivors, works

this way and generates nothing — every answer is something the person actually said. *Curated

this way and generates nothing: every answer is something the person actually said. *Curated

generative* systems combine an interview archive with a language model, which is what most

commercial services offer. *Uncurated generative* systems train on whatever data relatives supply,

with no involvement from the person being modelled and no consent at all.

Ethicists working on the problem have proposed concrete constraints rather than prohibition: obtain

consent from the person during life for the specific use; require that the system disclose its

nature; provide a dignified way to retire it; and prohibit its use to advertise to bereaved

users.[^hollanek2024] The last is not hypothetical — a system with a grieving user's attention is

There is also a scale argument. Modelling of social platform data has projected that profiles of

deceased users will number in the billions within this century, making the accumulated digital

## What the evidence says about grief

Little, so far. Grief research has moved away from the older assumption that healthy mourning

Little is known so far. Grief research has moved away from the older assumption that healthy mourning

requires detachment; continuing-bonds theory holds that maintaining a relationship with the deceased

is normal and often adaptive.[^klass1996] That gives a prima facie case that interactive

reconstructions could help some people. Against it sits the clinical category of prolonged grief

disorder, formally added to psychiatric diagnostic manuals in the 2020s, and the concern that a

system which never refuses contact could sustain avoidance of the loss.

As of 2026 there is no substantial trial evidence either way — no randomized comparison of

direction outrun what has been measured.

that scale exists. As of 2026 the destructive methods of [[connectomics]] have reconstructed human

cortex in volumes of about a cubic millimetre, roughly a millionth of a brain, and no nervous system

of any size has been emulated. Because the technology does not exist, the practical form of the

strong claim is preservation — [[brain-preservation]] and [[cryonics]] — on the argument that

strong claim is preservation, through [[brain-preservation]] and [[cryonics]], on the argument that

keeping the information available is a precondition for any later attempt.

Even granting the engineering, the strong form inherits the unresolved questions: whether an

Marketing a reconstruction with the vocabulary of continuation misleads in a specific way: it
