A Bayesian theory of death

The sinking of the superyacht displays the probability, and banality, of death.

On any statistical calculation, the probability of dying by drowning when your luxury yacht suddenly and inexplicably sinks at anchor in the Mediterranean has to be extremely low. 

So it’s the cruellest of ironies that tech tycoon Mike Lynch should so die, along with his daughter and five others, having devoted his commercial life to the application of such statistical probabilities. He had named his yacht Bayesian after the 18th-century theorem that introduced the idea that probability expresses a degree of belief in an event. 

That doesn’t expressly mean religious belief. But, intriguingly, it doesn’t exclude it either. According to Thomas Bayes, who published his theorem in 1763, the calculable degree of belief may be based on prior knowledge about an event, such as the results of previous experiments, or on personal beliefs about it. 

In essence, you don’t believe your yacht will capsize in the night and sink in seconds, because your experience tells you so. That belief can mathematically be included in the probability of it happening. 

We can transfer the method into religious praxis. Christian belief in the event of resurrection, for instance, can be calculated in the probability that the deaths of the Lynches and others aboard the Bayesian are not the end of their existence. 

It’s an intriguing legacy of Lynch’s work for theologians. But it’s the sheer lack of probability of the lethal event occurring at all that lends it its random banality. It’s that death visited those asleep on a yacht in the small hours that lends this news story such tireless legs, not just that these were super-rich masters and mistresses of the universe. 

There have been bitter observations on social media that the Bayesian’s victims have commanded limitlessly greater attention than the many thousands of refugees who die in small-boat crossings of the Mediterranean every year.  

This is a category mistake. And again, Bayesian theory can be deployed. Experience supports our belief that crossing the sea in overcrowded and unseaworthy vessels can all too often lead to tragically terminal events. The probability of death is plain. Again, it’s the sheer randomness of the Bayesian yacht event that sets it apart. 

If death can visit at any time, there can be no difference in the valuation of long or short lives. 

That randomness brings us back to the banality of sudden death among us, almost its ordinariness, something that just happens, often entirely out of the blue. The prayer book has the funeral words “in the midst of life we are in death”, meaning that death is our constant living companion. But that doesn’t quite cut it for me, because it tells us it’s there, but nothing of its true significance. 

The tenets of Christian faith are regularly said to be those of a death cult; that it’s a deep-seated fear of death that leads us to avoid it with assurances of eternal life. But it’s the sheer banality of death, as displayed in the randomness of the Bayesian event, that seems to knock down that idea. In its randomness, death looks ridiculous rather than evil. 

Conspiracy theories around the sinking of the Bayesian are a kind of denial of the reality of death too. We want there to be more to it than the utterly banal.

Author Hannah Arendt coined the phrase “the banality of evil” when covering the trial of Nazi holocaust architect Adolf Eichmann in Jerusalem. I’d want to suggest that it’s that same banality, that basic human ordinariness, that is the real nature of the supposed grim reaper, rather than his evil.   

None of this can comfort the Lynch family, who mourn the loss of a much-loved father and his young daughter, or the families of the others who lost their lives on the Bayesian. But it is meant to go some way towards an explanation of what we mean in Christian theology when we bandy about phrases such as “the defeat of death”. Because it’s not a wicked serpent that’s been defeated, more of a pointless clown. 

There is something especially painful about the death of the young, such as that of 18-year-old Hannah Lynch on the Bayesian that night, a young woman on the threshold of life. And – God knows – the even younger lives we’ve read about being taken lately. 

But the concept of banality may lead us to another tenet of faith: The completeness of every life. If death can visit at any time, there can be no difference in the valuation of long or short lives.  

A poem, often ascribed to a former dean of St Paul’s cathedral, begins with the line: “Death is nothing at all.” That’s wrong, as an idea. Death is as significant an event as birth. But its defeat is in keeping it in its place. 

The dignity in simplicity with which football manager Sven-Göran Eriksson greeted his final illness is a masterclass in this tactic for life. Death isn’t to be negotiated, it’s just there. 

In the end, death isn’t a Bayesian probability, it’s a certainty, for all of us. The difference, in Bayesian theory, must be the belief we bring to our personal calculations of the probability of the event.

AI deadbots are no way to cope with grief

The data we leave in the cloud will haunt and deceive those we leave behind.

What happens to all your data when you die? Over the years, like most people, I've produced a huge number of documents, letters, photos, social media posts, recordings of my voice, all of which exist somewhere out there in the cloud (the digital, not the heavenly one). When I die, what will happen to it all? I can't imagine anyone taking the time to climb into my Dropbox folder or Instagram account and delete it all? Does all this stuff remain out there cluttering up cyberspace like defunct satellites orbiting the earth?  

The other day I came across one way it might have a future - the idea of ‘deadbots’. Apparently, AI has now developed to such an extent that it can simulate the personality, speech patterns and thoughts of a deceased person. In centuries past, most people did not leave behind much record of their existence. Maybe a small number of possessions, memories in the minds of those who knew them, perhaps a few letters. Now we leave behind a whole swathe of data about us. AI is now capable of taking all this data and creating a kind of animated avatar, representing the deceased person, known as a ‘deadbot’ or even more weirdly, a ‘griefbot’. 

You can feel the attraction. An organisation called ‘Project December’ promises to ‘simulate the dead’, offering a ghostly video centred around the words ‘it’s been so long: I miss you.’ For someone stricken with grief, wondering whether there's any future in life now that their loved one has gone, feeling the aching space in the double bed, breakfast alone, the silence where conversation once filled the air, the temptation to be able to continue to interact and talk with a version of the deceased might be irresistible. 

There is already a developing ripple of concern about this ‘digital afterlife industry’. A recent article in Aeon explored the ethical dilemmas. Researchers in Cambridge University have already called for the need for safety protocols against the social and psychological damage that such technology might cause. They focus on the potential for unscrupulous marketers to spam surviving family or friends with the message that they really need XXX because ‘it's what Jim would have wanted’. You can imagine the bereaved ending up being effectively haunted by the ‘deadbot’, and unable to deal with grief healthily. It can be hard to resist for those whose grief is all-consuming and persistent. 

Yet it's not just the financial dangers, the possibility of abuse that troubles me. It's the deception involved which seems to me to operate in at a number of ways. And it's theology that helps identify the problems.  

The offer of a disembodied, AI-generated replication of the person is a thin paltry offering, as dissatisfying as a Zoom call in place of a person-to-person encounter. 

An AI-generated representation of a deceased partner might provide an opportunity for conversation, but it can never replicate the person. One of the great heresies of our age (one we got from René Descartes back in the seventeenth century) is the utter dualism between body and soul. It is the idea that we have some kind of inner self, a disembodied soul or mind which exists quite separately from the body. We sometimes talk about bodies as things that we have rather than things that we are. The anthropology taught within the pages of the Bible, however, suggests we are not disembodied souls but embodied persons, so much so that after death, we don't dissipate like ethereal ‘software’ liberated from the ‘hardware’ of the body, but we are to be clothed with new resurrection bodies continuous with, but different from the ones that we possess right now. 

We learned about the importance of our bodies during the COVID pandemic. When we were reduced to communicating via endless Zoom calls, we realised that while they were better than nothing, they could not replicate the reality of face-to-face bodily communication. A Zoom call couldn't pick up the subtle messages of body language. We missed the importance of touch and even the occasional embrace. Our bodies are part of who we are. We are not souls that happen to temporarily inhabit a body, inner selves that are the really important bit of us, with the body an ancillary, malleable thing that we don't ultimately need. The offer of a disembodied, AI-generated replication of the person is a thin paltry offering, as dissatisfying as a virtual meeting in place of a person-to-person encounter. 

Another problem I have with deadbots, is that they fix a person in time, like a fossilised version of the person who once lived. AI can only work with what that person has left behind - the recordings, the documents, the data which they produced while they were alive. And yet a crucial part of being human is the capacity to develop and change. As life continues, we grow, we shift, our priorities change. Hopefully we learn greater wisdom. That is part of the point of conversation, that we learn things, it changes us in interaction with others. There is the possibility of spiritual development of maturity, of redemption. A deadbot cannot do that. It cannot be redeemed, it cannot be transformed, because it is, to quote U2, stuck in a moment, and you can’t get out of it.  

This is all of a piece with a general trajectory in our culture which is to deny the reality of death. For Christians, death is an intruder. Death - or at least the form in which we know it, that of loss, dereliction, sadness - was not part of the original plan. It doesn't belong here, and we long for the day when one day it will be banished for good. You don’t have to be a Christian to feel the pain of grief, but paradoxically it's only when you have a firm sense of hope that death is a defeated enemy, that you can take it seriously as a real enemy. Without that hope, all you can do is minimise it, pretend it doesn't really matter, hold funerals that try to be relentlessly cheerful, denying the inevitable sense of tragedy and loss that they were always meant to express.  

Deadbots are a feeble attempt to try to ignore the deep gulf that lies between us and the dead. In one of his parables, Jesus once depicted a conversation between the living and the dead:  

“between you and us a great chasm has been fixed, so that those who might want to pass from here to you cannot do so, and no one can cross from there to us.”  

Deadbots, like ‘direct cremations’, where the body is disposed without any funeral, denying the bereaved the chance to grieve, like the language around assisted dying that death is ‘nothing at all’ and therefore can be deliberately hastened, are an attempt to bridge that great chasm, which, this side of the resurrection, we cannot do. 

Deadbots in one sense are a testimony to our remarkable powers of invention. Yet they cannot ultimately get around our embodied nature, offer the possibility of redemption, or deal with the grim reality of death. They offer a pale imitation of the source of true hope - the resurrection of the body, the prospect of meeting our loved ones again, yet transformed and fulfilled in the presence of God, even if it means painful yet hopeful patience and waiting until that day.
