The summit of humanity: decoding AI's affectations

An AI summit’s prophecies need to be placed in the right philosophical register, argues Simon Cross. Because being human in an AI age still means the same thing it has for millennia.

Simon Cross researches ethical aspects of technology and advises on the Church’s of England's policy and legislative activity in these areas.

The UK’s global artificial intelligence (AI) conference is nearly upon us. If the UK had a ‘prophecy office’ it would have issued a yellow or even amber warning for the first days of November by now. Prophecy used to be a dangerous business, the ancient text of Deuteronomy sanctioned death for false prophets, equating its force with a leading away from God as the ultimate ground of truth. But risks duly acknowledged, here is a prophecy about the prophecies to come. The global AI conference will loudly proclaim three core prophecies about AI. 

  1. This time it’s different. Yes, we said that before but this time it really is different. 
  2. Yes, we need global regulation but, you know, it’s complicated so only the kind of regulation we advise is going to work.  
  3. Look, if we don’t do this someone else will. So, you should get out of our way as much as you possibly can. We are the good guys and if you slow us down the bad guys will win. 

I feel confident about this prediction not because I wish to claim the office of prophet but because just like Big Tobacco and Big Oil, Big Tech’s lobbyists will redeploy a tried and tested playbook. And here are the three plays at the heart of it. 

Tech exceptionalism. (We deserve to be treated differently under the law.) 

Regulatory capture. (We got lucky, last time, with the distinction between platform and publisher that permitted self-regulation of social media, the harvesting of personal data and manipulative design for attention, but the costs of defeating Uber in California and now defending rearguard anti-trust lawsuits means lesson learned, we need to go straight for regulatory capture this time). 

Tech determinism. (If we don’t do it, someone else will. We are the Oppenheimers here.) 

Speaking of Pandora 

What should we make of these claims? We need to start by exploring an underlying premise. One that typically goes like this “AI is calling into question what it means to be human”. 

This premise has become common currency, but it is flawed because it is too totalising. AI emphatically is calling into question a culturally dominant version of human anthropology – one specific ‘science of humanity’. But not all anthropologies. Not the Christian anthropology.  

A further, unspoken, premise driving this claim becomes clearer when we survey the range of responses to the question “what does the advent of what the government is now calling ‘frontier’ AI portend?”  

Either, it means we have finally prized open Pandora’s box; the last thing humans will ever create. AI is our Darwinian evolutionary heir, soon to make us homo sapiens redundant, extinct, even. Which could happen in two very different ways. For some, AI is the vehicle to a new post-human eternal life of ease, roaming the farthest reaches of the universe in disembodied digital repose. To others, AI is now on the very cusp of becoming abruptly and infinitely cleverer than us. To yet others, we are too stupid to avoid blowing ourselves up on the way to inventing so-called artificial general intelligence.  

Cue main global summit speaking points… 

Or, 

AI is just a branch of computing. 

Which of these two starkly contrasting options you choose will depend on your underlying beliefs about ‘what it means to be human’. 

Universal machines and meat machines 

Then again, what does it mean to be artificially intelligent? Standard histories of AI always point to two seminal events. First, Alan Turing published a paper in the 1930s in which he proposed a device called a Universal Turing Machine.  

Turing’s genius was to see a way of writing a type of programme to control a computer’s underlying binary on/off in ways that could vary depending on the task required and yet perform any task a computer can do. The reason your computer is not just a calculator but an excel spreadsheet and a word processor and a video player as well is because it is a kind of Universal Turing Machine. A UTM can compute anything that can be computed. If it has the right programme.  

The second major event in AI folklore was a conference at Dartmouth College in the USA in the early 1950s bringing together the so-called ‘godfathers of AI’.

 This conference set the philosophical and practical approaches from which AI has developed ever since. That this happened in America is important because of the strong link between universities, government, the defence and intelligence industry and the Big Tech Unicorns that have emerged from Silicon Valley to conquer the world. That link is anthropological; it is political, social, and economic and not just technical. 

Let’s take this underlying question of ‘what does it mean to be human?’ and recast it in a binary form as befits a computational approach; ‘Is a human being a machine or is a human being an organism?’ 

Cognitive scientist Daniel Dennett was recently interviewed in the New York Times. For Dennett our minds and bodies are a “consortia of tiny robots”. Dennett is an evolutionary biologist and a powerful voice for a particular form of atheism and its answer to the question ‘what does it mean to be human?’ Dennett regards consciousness as ephemera, a by-product of brain activity. Another godfather of AI, Marvin Minsky, famously described human beings as ‘meat machines.’

By contrast, Joseph Weizenbaum was also one of the early computer pioneers in the 1960s and 1970s. Weizenbaum created one of the first ever chatbots, ELIZA– and was utterly horrified at the results. His test subjects could not stop treating ELIZA as a real person. At one point his own secretary sat down at the terminal to speak to ELIZA and then turned to him and asked him to leave the room so she could have some privacy. Weizenbaum spent the latter part of his professional life arguing passionately that there are things we ought not to get computers to do even if they can, in principle, perform them in a humanlike manner. To Joseph Weizenbaum computers were/are fundamentally different to human beings in ways that matter ineluctably, anthropologically. And it certainly seems as if the full dimensionality of human being cannot yet be reduced to binary on/off internal states without jettisoning free will, consciousness and transcendence. Prominent voices like Dennett and Yuval Noah Harari are willing to take this intellectual step. Their computer says ‘no’. By their own logic it could not say otherwise. In which case here’s a third way of asking that seemingly urgent and pressing question about human being;  

“Are we just warm, wet, computers?” 

The immanent frame 

A way to make sense of this, for many people, influential and intuitively attractive meaning of human being is to understand how the notion of artificial intelligence fits a particular worldview that has come to dominate recent decades and, indeed, centuries. 

In 2007 Charles Taylor wrote A Secular Age. In it he tracks the changing view of what it means to be human as the Western Enlightenment unfolds. Taylor detects a series of what he calls ‘subtraction stories’ that gradually explain away the central human experience of transcendence until society is left with what he calls an ‘immanent frame’. Now we are individual ‘buffered selves’ insulated by rational mind so that belief in any transcendent reality, let alone God, is just one possible choice among personal belief systems. But, says Taylor, this fracturing of a shared overarching answer to the question ‘What does it mean to be human’ over the past, say, 500 years doesn’t actually answer the question or resolve the ambiguities. Rather, society is now subject to what Taylor calls ‘cross pressures’ and a lack of societal consensus about the answers to the biggest questions of human meaning and purpose. 

In this much broader context, it becomes easier to see why as well as how it can be the case that AI is either a profound anthropological threat or just a branch of computing – depending on who you talk to… 

The way we describe AI profoundly influences our understanding of it. When Dennett talks about a ‘consortia of tiny robots’ is he speaking univocally or metaphorically? What about when we say that AI “creates”, or “decides” or “discovers” or ‘seeks to maximise its own reward function’. How are we using those words? If we mean words like ‘consortia’ or ‘choose’ and ‘reward’ in as close to the human sense as makes no difference, then of course the difference between us and our machines becomes paper-thin. But are human beings really a kind of UTM? Are UTMs really universal? Are you a warm wet computational meat-machine?  

Or is AI just the latest and greatest subtraction story?

To say AI is just a branch of computing is not to say the harms of outsourcing key features of human being to machines are trivial. Quite the opposite. 

How then should we judge prophecies about AI emanating from this global conference or in the weeks and months to follow?  I suggest two responses. The first follows from my view of AI, the other from my view of human being.  

Our view of current AI should be clear eyed, albeit open to revision should future development(s) so dictate. I am firmly on the side of those who, without foreclosing the possibility, see no philosophical breakthrough in the current crop of tools and techniques. These are murky philosophical waters but clocks don’t really have human hands now do they, and a collapsed metaphor can’t validate itself however endemic the reference to the computational theory of mind has become.  

Google’s large language model, Bard, for example, has no sense of what time it is where ‘he’ is, let alone can freely choose to love you or not, or to forgive you if you hurl an insult at ‘him’. But all kinds of anthropological harms already flow from the unconscious consequences of re-tuning human being according to the methodological image of our machines. To say AI is just a branch of computing is not to say the harms of outsourcing key features of human being to machines are trivial. Quite the opposite. 

Which brings me to the second response. When you hear the now stock claim that AI is calling into question what it means to be human, don’t buy it. Push back. Point out the totalising lack of nuance. The latest tools and techniques of AI are calling a culturally regnant but philosophically reductive anthropology into question. That much is definitely true. But that is all. 

And it is important to resist this totalising claim because if we don’t, an increasingly common and urgent debate about the fullness of human being and the limitations of UTMs will struggle from the start. One of the biggest mistakes I think public theology made twenty-some years ago was to cede a normative use of language that distinguished between people of faith and people of no faith. There is no such thing as being human without faith commitments of one kind or another. If you have any doubt about this, I commend No One Sees God: The Dark Night of Atheists and Believers by Michael Novak. But the problem with accepting the false distinction between ‘having faith’ and having ‘no faith’ is that it has allowed the Dennetts and Hararis of this world to insist that atheism is on a stronger philosophical footing than theism. After which all subsequent debate had, first, to establish the legitimacy of faith per se before getting to the particular truth claims in, say, Christianity.  

What it means to be human 

I see a potentially similar misstep for anthropology – the science of human being – in this new and contemporary context of AI. Everywhere at the moment, and I mean but everywhere, a totalising claim is being declared ever more loudly and urgently: that the tools and techniques of AI are calling into question the very essence of human identity. The risk in ceding this claim is that we get stuck in an arid debate about content instead of significance; a debate about ‘what it means to be human’ instead of a debate about ‘what it means to be human.’  

This global AI summit’s proclamations and prophecies need to be placed in the right philosophical register, because to be human in an age of AI still means the same thing it has for millennia.  

Universals like wonder, love, justice, the need for mutually meaningful relationships and a sense of purpose, and so too personal idiosyncrasies like a soft spot for the moose are central features of what it means to be this human being.  

Suchlike are the essential ingredients of the ‘me’ that is reading this article. They are not tertiary. Perhaps they can be computationally mimicked but that does not mean they are, in themselves, ephemeral or mere artifice. In which case their superficial mimicry carries substantial risks, just as Joseph Weizenbaum prophesied in Computer Power and Human Reason in the 1970s.  

Of course, you may disagree. You may even disagree in good faith, for there are no knockdown arguments in metaphysics. And in my worldview, you are free to do so. But fair warning. If the human-determinism of Dennett or the latest prophecies of Harari are right, no credit follows. You, and they, are right only because by arbitrary alignment of the metaphysical stars, you, and they, have never been free to be wrong. It was all decided long ago. No need for prophecies. We are all just UTMs with the soul of a marionette  

But when you hear the three Global summit prophecies I predicted earlier, consider these three alternatives; 

This time is not different, it is not true that AI is calling into question all anthropologies. AI is (only) calling into question a false and reductive Enlightenment prophecy about ‘what it means to be human.’  

The perennial systematic and doctrinal anthropology of Christianity understands human being as free-willed, conscious, unified body soul and spirit.  It offers credible answers to the urgent questions and cross-pressures society is now wrestling with. It also offers an ethical framework for answering the question ‘what ought computers to be used for and what ought computers not to be used for – even if they appear able to be used for anything and everything? 

This Christian philosophical perspective on the twin underlying metaphysical questions of human being and purpose are not being called into question, either at this global summit or by any developments in AI today or the foreseeable future. They can, however, increasingly be called into service to answer those questions – at least for those with ears to hear.

The healing touch in an era of personalised medicine

As data powers a revolution in personalised medicine, surgeon David Cranston asks if we are risk of dehumanising medicine?

David Cranston is emeritus Professor of Surgery at Oxford University. As well as publishing academically, he has has also authored books on John Radcliffe, and mentoring.

In 1877 Arthur Conan Doyle was sitting in one of Dr Joseph Bell’s outpatient clinics in Edinburgh as a medical student, when a lady came in with a child, carrying a small coat. Dr Bell asked her how the crossing of the Firth of Forth had been on the ferry that morning. Looking sightly askance she replied;  

 “Fine thank you sir.”  

 He then went on to ask what she had done with her younger child who came with her.  

Looking more astonished she said:   

“I left him with my aunt who lives in Edinburgh.   

Bell goes on to ask if she walked through the Botanic Gardens on the way to his clinic and if she still worked in the Linoleum factory and to both these questions she answered in the affirmative.  

Turning to the students he explained  

“I could tell from her accent that she came from across the Firth of Forth and the only way across is by the ferry. You noticed that she was carrying a coat which was obviously too small for the child she had with her, which suggested she had another younger child and had left him somewhere. The only place when you see the red mud that she has on her boots is in the Botanic Gardens  and the skin rash on her hands is typical of workers in the  Linoleum factory.   

It was this study of the diagnostic methods of Dr Joseph Bell led Conan Doyle to create the character of Sherlock Holmes.  

A hundred years later and I was young doctor. In 1977 there were no CT or MRI scanners. We were taught the importance of taking a detailed history and examination. Including the social history. We would recognise the RAF tie and the silver (silk producing) caterpillar badge on the lapel of a patient jacket.  We would ask him when he joined the caterpillar club and how many times he had had to bail out of his plane when he was shot down during the war – a life saved by a silk parachute. We would notice the North Devon accent in a lady and ask when she moved to Oxford.  

The patient’s history gave 70% of the diagnosis, examination another 20% and investigation the final 10%. Patients came with symptoms and the doctor made a presumptive diagnosis – often correct - which was confirmed by the investigations. Screening for disease in patients with no symptoms was in its infancy and diseases were diagnosed by talking to the patients and eliciting a clear history and doing a meticulous examination. No longer is that the case.     

At the close of my career, as a renal cancer surgeon, most people came in with a diagnosis already made on the basis of a CT scan, and often small kidney cancers were picked up incidentally with no symptoms. The time spent talking to patients was reduced. On one hand it means more patients can be seen but on the other the personal contact and empathy can be lost.  

Patients lying in in bed have sometimes been ignored. The consultant and the team standing around the foot of the patient’s bed discussing their cases amongst themselves. Or, once off the ward, speaking of the thyroid cancer in bed three or the colon cancer in bed two. Yet patients are people too with histories behind them and woe betide the medic, or indeed the government, who forgets that.  

With computer aided diagnosis, electronic patient records and more sophisticated investigation the patient can easily become even more remote. An object rather than a person.  

We speak today of more personalised medicine with every person having tailored treatment of the basis of whole genome sequencing and knowing each individual’s make up. But we need to be sure that this does not lead to less personalised medicine by forgetting the whole person, body mind and spirit.  

Post Covid, more consultations are done online or over the telephone -often with a doctor you do not know and have never met. Technology has tended to increase the distance between the doctor and patient. The mechanisation of scientific medicine is here to stay, but the patient may well feel that the doctor is more interested in her disease than in herself as a person. History taking and examination is less important in terms of diagnosis and remote medicine means that personal contact including examination and touch are removed.  

Touching has always been an important part of healing. Sir Peter Medawar, who won the Nobel prize for medicine sums it up well. He asks:  

‘What did doctors do with those many infections whose progress was rapid and whose outcome was usually lethal?   

He replies:  

'For one thing, they practised a little magic, dancing around the bedside, making smoke, chanting incomprehensibilities and touching the patient everywhere.? This touching was the real professional secret, never acknowledged as the central essential skill.'

Touch has been rated as the oldest and most effective act of healing.   

Touch can reduce pain, anxiety, and depression, and there are occasions when one can communicate far more through touch than in words, for there are times when no words are good enough or holy enough to minister to someone’s pain.   

Yet today touching any patient without clear permission can make people ill at ease and mistrustful and risk justified accusation. It is a tightrope many have to walk very carefully. In an age of whole-person care it is imperative that the right balance be struck. There’s an ancient story that illustrates the power of that human connection in the healing process. 

When a leper approached Jesus in desperation, Jesus did not simply offer a healing word from safe distance. he stretched out his hand and touched him. He felt deeply for lepers cut off from all human contact. He touched the untouchables.   

William Osler a Canadian physician who was one of the founding fathers of the Johns Hopkins Hospital in Baltimore, and ended up as Regius Professor of Medicine in Oxford,  said:  

“It is more important to know about the patient who has the disease than the disease that has the patient”.  

For all the advantages modern medicine has to offer, it is vital to find ways to retain that personal element of medicine. Patients are people too.
