Is digital immortality possible?

Updated 18 October 2026 · 2 min read

No. Not in the sense of a person living on. But a surprising amount of how someone talked, what they remembered and what they cared about can now be kept, and that is worth understanding clearly.

What "possible" would have to mean

For digital immortality to be real, something would have to carry on a person's experience: their awareness, their feelings, their ability to change their mind tomorrow. Nothing we can build today does that, and there is no agreed scientific path to it. Every product that uses the phrase is doing something more modest.

What current AI can do

Large language models are very good at style. Given enough of a person's own words, they can answer new questions in a way that sounds like that person: their phrases, their humour, their usual opinions, the stories they tell. Add a voice made from their recordings and the result can feel close.

• Stories and facts: what the person told, about their childhood, their work, the family.
• Way of talking: word choice, rhythm, what they would say and what they wouldn't.
• Values and opinions: what they believed about money, children, faith, work.
• Voice: the sound of them, with consent, from their own recordings.

Where it stops

• It only knows what it was told. A copy built from twenty answers knows twenty answers. Good systems say "I don't know" rather than invent.
• It doesn't grow. A person would have changed their view over the years. A copy reflects who they were in what they left.
• It can be wrong. Language models sometimes guess. A copy can say something the person never would have.
• It is not aware. It does not miss you, remember you between conversations in a human sense, or feel anything.

Is it still worth doing?

For many families, yes, for a plain reason: the alternative is losing those answers entirely. Most of us have a question we wish we had asked a grandparent. A careful copy, built while the person is alive and with their help, keeps far more than a photo album: how they explained things, the stories behind the photos, their voice saying them.

The value comes from honest expectations. It is a way of remembering and of asking, not a way of having someone back. We explain this at length in can AI preserve a human personality?

What makes a copy better

1. Their own words, in quantity. Many answers, in their voice, about many parts of life.
2. Real conversations. Chats and voice messages show how they actually talked, not how they write when asked.
3. Several people's memories. Siblings remember different stories.
4. Starting early. The best copies are made with the person, while they can still answer.

This is how OtherMy works: you answer questions or let your parent answer by talking, add memories, recordings and chats, and invite your brothers and sisters to add theirs. Our guide on how to save a parent's voice walks through it.

In short

Digital immortality is not possible. Keeping a person's voice and stories well enough that their family can still ask them things is, and it is easiest while they are here to help.
