“I’m begging you, I’m begging you,” pleaded the passenger. His two large suitcases lying around him, the Nigerian man knelt on the pavement outside the Megabus station. The bus driver stood surly-faced, arms crossed. The passenger’s jacket was ripped where the driver had shoved him off the bus. The passenger had one too many bags; he had not read the Terms and Conditions on his ticket.

The man groaned – “I must get to Heathrow, I have a flight to catch! I’m willing to do anything – to pay for an extra ticket, to pay the extra bag fee, I have money, see?” He showed the driver his wallet pleadingly, demonstrating his possession of several bank cards.

A few concerned passengers stepped off the bus. “We don’t have a bag in the hold; we’re happy for this man to have our space.” Another person said, “I booked a ticket but my friend didn’t come – there’s a whole seat’s worth of luggage space available in the hold.” Yet the bus driver would not budge. Even though Megabus has an excess baggage policy, it was down to the driver’s discretion. The driver alone had the power of life and death, to say “yay” or “nay” – to restore a man’s dignity or completely ruin it, along with his jacket.

As the minutes ticked on, other passengers began to get irate with the Nigerian man – “just buzz off mate, you’re making us late!” “You should have read the rules!” “You’re making the bairns on the bus cry!” Stony faces pressed against the window as the man knelt on the pavement. Even those who had tried to help him left him in the harsh hands of the bus driver and his colleagues, tiny kings in a kangaroo court. For the bus driver, there was no backing down – he was pacing, sweating and red-faced, repeating over and over again to himself his side of the story. And in the end, we left the Nigerian passenger in the heartless hands of bus bureaucracy, wiping our hands of the injury done to him – “we tried.”

How mucky and murky the human heart can be.

The whole experience on the Megabus that day left me feeling sick. We all like to think of ourselves as decent folks, as long as we do our “bit”. But on that bus I realized the difficulty: what is “my bit”? Who decides what is “enough”? How quickly a petty issue of baggage can descend into a power play. How quickly do ordinary nice people become a mob when they are outraged or inconvenienced. How mucky and murky the human heart can be.

The only word that feels strong enough to me to describe this condition is “sin”. This word may sound like a relic of a bygone Britain, but I think it’s as relevant as ever. It’s a serious word, loaded with a sense that the things we do mean more than we know. Sin suggests that I am accountable for how I treat people – not just to my own perception but some higher standard that safeguards the dignity of all human beings. Christians believe that it is God who safeguards our humanity, who sets the standard for how we should and should not treat others. We are accountable “vertically” – to God – as well as “horizontally” to each other.

It seems to me that “sin” is not a laundry-list of rules but more like a tangled knot of slippery threads – I can’t see where it begins and where it ends, in my own heart or in the world at large. The Christian Eastern Orthodox tradition often likens sin to sickness or a dis-ease of the soul; it infects our reasoning, our emotions and our actions. And that’s why the hurt and pain we cause each other is so “sticky” – no one is left untouched by the effects of the damage we cause each other.

It was quite clear to me that there were some “sins of deliberate fault” on the Megabus that day – the bus driver’s behaviour was patently unfair and verging on abuse. But I would say sin also flourished in the self-defending logic of the passengers who just wanted to stay in their lane, and for the Nigerian chap to stay in his. Don’t bother me, with your problems. I look after me, you look after you. There were sins of ignorance too – I felt this sick sense in my stomach as the bus pulled out of the station that there was more I could have done, but I didn’t quite know what. All I know is that every person needed mercy on that Megabus, whether we knew it or not. Ironically, the Nigerian man was the most innocent of all.

It's our mistakes that make us human

What we learn distinguishes us from tech.

The distinction between technology and human beings has become blurry: AI seems to be able to listen, answer our questions, even respond to our feelings. It becomes increasingly easy to confuse machines with humans. In this situation, it is increasingly important to ask: What makes us human, in distinction from machines? There are many answers to this question, but for now I would like to focus on just one aspect of what I think is distinctively human: As human beings, we live and learn in time.

To be human means to be intrinsically temporal. We live in time and are oriented towards a future good. We are learning animals, and our learning is bound up with the taking of time. When we learn to know or to do something, we necessarily make mistakes, and we take practice. But keeping in view something we desire – a future good – we keep going.

Let’s take the example of language. We acquire language in community over time. Toddlers make all sorts of hilarious mistakes when they first try to talk, and it takes them a long time even to get single words right, let alone to try and form sentences. But they keep trying, and they eventually learn. The same goes with love: Knowing how to love our family or our neighbours near and far is not something we are good at instantly. It is not the sort of learning where you absorb a piece of information and then you ‘get’ it. No, we learn it over time, we imitate others, we practice and even when we have learned, in the abstract, what it is to be loving, we keep getting it wrong.

This, too, is part of what it means to be human: to make mistakes. Not the sort of mistakes machines make, when they classify some information wrongly, for instance, but the very human mistake of falling short of your own ideal. Of striving towards something you desire – happiness, in the broadest of terms – and yet falling short, in your actions, of that very goal. But there’s another very human thing right here: Human beings can also change. They – we – can have a change of heart, be transformed, and at some point in time, actually start to do the right thing – even against all the odds. Statistics of past behaviours, do not always correctly predict future outcomes. Part of being human means that we can be transformed.

Transformation sometimes comes suddenly, when an overwhelming, awe-inspiring experience changes somebody’s life as by a bolt of lightning. Much more commonly, though, such transformation takes time. Through taking up small practices, we can form new habits, gradually acquire virtue, and do the right thing more often than not. This is so human: We are anything but perfect. As Christians would say: We have a tendency to entangle ourselves in the mess of sin and guilt. But we also bear the image of the Holy One who made us, and by the grace and favour of that One, we are not forever stuck in the mess. We are redeemed: are given the strength to keep trying, despite the mistakes we make, and given the grace to acquire virtue and become better people over time. All of this to say that being human means to live in time, and to learn in time.

So, this is a real difference between human beings and machines: Human beings can, and do strive toward a future good.

Now compare this to the most complex of machines. We say that AI is able to “learn”. But what does it mean to learn, for AI? Machine learning is usually categorized into supervised learning, unsupervised and self-supervised learning. Supervised learning means that a model is trained for a specific task based on correctly labelled data. For instance, if a model is to predict whether a mammogram image contains a cancerous tumour, it is given many example images which are correctly classed as ‘contains cancer’ or ‘does not contain cancer’. That way, it is “taught” to recognise cancer in unlabelled mammograms. Unsupervised learning is different. Here, the system looks for patterns in the dataset it is given. It clusters and groups data without relying on predefined labels. Self-supervised learning uses both methods: Here, the system uses parts of the data itself as a kind of label – such as, for instance, predicting the upper half of an image from its lower half, or the next word in a given text. This is the predominant paradigm for how contemporary large-scale AI models “learn”.

In each case, AI’s learning is necessarily based on data sets. Learning happens with reference to pre-given data, and in that sense with reference to the past. It may look like such models can consider the future, and have future goals, but only insofar as they have picked up patterns in past data, which they use to predict future patterns – as if the future was nothing but a repetition of the past.

So this is a real difference between human beings and machines: Human beings can, and do strive toward a future good. Machines, by contrast, are always oriented towards the past of the data that was fed to them. Human beings are intrinsically temporal beings, whereas machines are defined by temporality only in a very limited sense: it takes time to upload data, and for the data to be processed, for instance. Time, for machines, is nothing but an extension of the past, whereas for human beings, it is an invitation to and the possibility for being transformed for the sake of a future good. We, human beings, are intrinsically temporal, living in time towards a future good – which machines do not.

In the face of new technologies we need a sharpened sense for the strange and awe-inspiring species that is the human race, and cultivate a new sense of wonder about humanity itself.
