I will be the first to admit that I am neither cool nor edgy. Jesus turned me from a mechanical engineer into a moral theologian, and age turned me into a spinster who can’t stay out past 8 p.m. Until quite recently, I never imagined I would end up at an event that was splashed all over the British tabloid press and only moved to London after it had been banned from Malaysia.

But I did.

Just before Christmas, I attended the Second Annual Congress on Love and Sex with Robots at Goldsmiths College of the University of London. Pace some accounts in the popular press, this was a serious academic conference, featuring researchers in computer science, machine ethics, classics, psychology, and more. I was there as a scholar who studies the ways that scientific modernity shapes our lives, but I was also there as a priest.

As it turned out, that was the only way I could make sense of what was going on. I thought I could write a lighthearted article lampooning the foolishness of what happened there, but in the end, I couldn’t. Let me explain.

The idea of human-robot sex has exploded into public consciousness. We may blame the popularity of the HBO series Westworld, in which customers at a futuristic Old West theme park pay to do whatever they want to, or with, robotic characters that are indistinguishable from human beings. It’s a recurrent theme in science fiction, appearing in recent films including Her and Ex Machina, as well as the 1927 Fritz Lang classic Metropolis. For the past two years, however, scholars from various fields have gathered to discuss what they believe is an inevitable future of robotic love.

The scholarly study of robot sex, such as it is, found its first major proponent in David Levy, a chess grand master and artificial-intelligence researcher. His book on the subject, Love and Sex with Robots, was published in 2008, and he served as one of the conference’s keynote speakers. His argument, a mix of technological utopianism and well-meaning humanitarian sentiment, runs approximately as follows:

1. Artificial intelligence research will soon create robots that are, for all practical purposes, indistinguishable from humans.

2. Many people in this world suffer from loneliness and a lack of companionship.

3. Therefore, human beings should be able to (and soon will) fall in love with and marry a robot.

It takes only a little thoughtful attention to see the conflations and confusions in this argument, and possible Christian responses to them are too multifarious to cover completely in this brief essay. Immediately, of course, fundamental questions of theological anthropology spring to mind.

What is a human being? What are the contours of human intimacy? What are sex and marriage for?

These are crucially important matters, and my colleagues at The Living Church and elsewhere in the Anglican world have devoted much study and reflection to them over the years. For now, however, I will follow Emily Dickinson’s injunction to “tell the truth and tell it slant,” in the hope that asking slightly different questions may help the Church as we think about how to respond to this brave new technological problem — that is in reality not very new at all.

My first question arises from my experience in the world of engineering, where I specialized in building mathematical models of aircraft and satellites. Any model — any digitized approximation — of something that exists in the physical world is only ever an approximation. It may be a valid and complex approximation fit for engineering work, or it may be something as crude as the pixelated world of Minecraft (with which many parents are all too familiar). In constructing digital simulations of the real world, however complex, the human builder decides which features are important enough to be simulated, and which are adiaphora. For this reason, I believe that the critical point is not Can a robot love? but What would a human being think is an accurate-enough simulation of a human beloved? And here we enter the world of theology and ethics, of which I am currently a resident.

The utopias (and dystopias) we construct for ourselves may or may not tell us much about the actual future we will inhabit, but they can do significant work to unmask the present. They can show us how we understand the world and the shape of our desires. Careful readers of science fiction, of course, understand this. Latent in the idea of human-robot love is the assumption that love is a set of algorithmic transactions that can be quantified, delineated, and programmed into a computer. In this line of thinking, the difference between programming an IBM supercomputer like Deep Blue to play chess and programming a robotic lover is merely a matter of complexity and scale. There may be more rules to human relationships, but once we know what they are, the difficult part of the problem is solved.

This is not a new story. Mathematicians, economists, and computer scientists have been writing about marriage in terms of game theory since the 1960s.[1] The problem of thinking that human relationships can be described by an algorithm is a problem of knowledge. Can mathematics and mechanics descriptively and constructively encompass everything that is?

A second question, which lies within the first, is Why would anyone want to try? Technological hubris is the most obvious answer, what Karl Barth called the “Titanism” that places human beings in the position of being their own saviors.[2] Relational hubris is another answer.

In Levy’s presentation, the language deployed to describe the ideal robotic spouse was inadvertently telling:

All of the following qualities and many more are likely to be achievable in software within a few decades. Your robot will be patient, kind, protective, loving, trusting, truthful, persevering, respectful, uncomplaining, complimentary, pleasant to talk to, and sharing your sense of humor.[3]

Suffice it to say for now that this statement reveals quite a bit about the priorities of the author, and very little about the task of technologically approximating any existing human woman.[4] Here is proof of my earlier point: Behind every simulation is a human being making choices about what to simulate.

Beyond these matters, however, lies a more poignant question that begs for healing as well as critique. Again and again in literature depicting or projecting human-robot love, we encounter the shadow of human beings who are unloved or who consider themselves unlovable. One presentation at the London conference began from the premise of robotic companionship apart from sex, appealing to the problem of isolation in the elderly residents of Japanese nursing homes. Another paper proposed robotic lovers as a solution for the “misfits” of life.[5] As Levy put it, technology can solve the problem of those “who just don’t have a relationship with someone they can love and someone who can love them.”[6]

As a scholar I find the question of technologically approximated love and lovers philosophically infuriating. But as a priest, as a friend, as family to some by nature and many more by the grace of baptism, I would like to suggest that critique of this phenomenon cannot be separated from honest engagement with the problem of alienation and isolation that is at once a story as ancient as human culture and newly pressing in this age we call modernity. Christians can, and should, engage critically with the proponents of technological hubris and progressive utopias. But we cannot do so without also addressing the ache behind the utopia, the quotidian dream of no longer being lonely.

A Christian witness against robotic caregivers must include caregiving for the sick and the forgotten. A Christian witness against robotic lovers must include friendship in community that tells a different story about intimacy that is not delineated and determined by sexual acts. And as my advisor Willie Jennings often tells his students, a Christian witness that rightly calls into question our fallen and twisted desires must also show us how to love.

And here, mechanics and mathematics cannot go. Here is the territory of daily miracle, of unexpected wonder, and of profligate gift.

Thanks again for this, Kara. So many questions spring to mind. At the moment, the question of simulation really does make me wonder, especially when it sounds as if lonely people are seeking companions they cannot otherwise find. Are we imagining some kind of companion who does not notice flaws? Or a robot companion that would learn about you and respond only in positive ways? In other words, beyond the idea that a robot could be purchased, how would they be programmed such that the relationship did not “go wrong”? And would anyone recognize that as love?

This question actually came up in the Q-and-A at one point! The answer was something like “Well, you can program in whatever idiosyncrasies you want.” Which was a very unsatisfactory answer. If you want someone who is prickly or doesn’t always respond well to you, you can indeed have that. (If I remember correctly, the word “frigid” may have even been used…a word about which gallons of ink have been spilled by feminist scholars through the years. As you might imagine, I was about to jump out of my seat at that point.) Of course, all this is still determined… Read more »

Some further elaboration along these lines: Designing the Beloved

Any discussion about a future of human-robot relationships should include a careful re-reading of Ray Bradbury’s I Sing the Body Electric!, in which a recently-widowed father of three hires an electric grandmother to come and live with the family; she becomes everything the children need, and she returns to them when their advancing years bring the problem of care in old age. The television film, with Maureen Stapleton, is also worth watching, and I believe that it’s called The Electric Grandmother.
