Digital Immortality: A Field I Am Still Learning to Read
I recently came across the term Thanatechnology for the first time. I had to look it up.
Thanatology is the study of death and dying, how humans experience loss, how we grieve, how we find our way through it. Thanatechnology is the newer, stranger cousin: all the digital tools that are now inserting themselves into that process. Platforms that preserve your digital presence after you die. Services that let you record messages for people you will leave behind. Apps designed to support grief. And, at the furthest edge of the field: AI systems that reconstruct deceased people from their messages, recordings and habits, so that the living can keep talking to them.
I am not an expert in this field. I am a psychologist by training, someone who has been watching AI develop for longer than most, and someone who finds these questions genuinely fascinating, and genuinely unresolved.
Remembrance versus simulation
What I keep thinking about is the difference between remembrance and simulation. A photograph, a voicemail, a handwritten letter, these are artefacts. They hold someone's presence without pretending to replace it. An AI that responds, adapts, and in some versions continues to develop, that is something different. It answers back. It adjusts to you. At some point the question becomes: who is actually speaking?
I do not have a clean answer to that. I am not sure anyone does yet.
A bridge is not a home
What I do know, from psychology and from my own experience with tools like PEACH, is that the purpose matters enormously. A bridge is useful when you are crossing it. It becomes something else when you stop crossing and start living there instead. Grief, as painful as it is, is not a malfunction. It is how we integrate loss and move forward. Whether technology can support that process, or whether it can quietly replace it, seems to me like one of the most important questions we are not quite asking loudly enough.
Thanatech is a field I am going to keep following. Not because I know where it leads, but because I think the questions it raises go far beyond death and grief. They go to the heart of what we actually want from machines that increasingly resemble us.
More on that soon.
