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.

Are we being anxious about anxiety?

Haidt's diagnosis of a 'doomed' youth is off. Instead, we should learn from them.

It’s common these days to hear about social anxiety, health anxiety, or climate anxiety – but I think I can see that a new pathology is beginning to emerge: anxiety anxiety. This is where parents, politicians, academics, or just members of society in general, start to get anxious about the fact that everybody is anxious. Diagnosis rates of clinical anxiety have shown a steep increase in the past decade, and numbers, we assume, don’t lie.

Of the many outcomes of ‘anxiety anxiety’, one is going to be people who (with the absolute best intentions) want to suggest solutions. One such person is Jonathan Haidt, with his book The Anxious Generation: How the Great Rewiring of Childhood is Causing an Epidemic of Mental Illness.

From the spaceman on the cover to the opening vignette about sending our children to Mars, Haidt’s premise is clear: smartphones are the alien invaders of our society. These electronic parasites are feasting on the brain matter of our young people, directly causing what is now an epidemic of clinical anxiety and depression.

I’m quite ready to read a sensible analysis of the impact of smartphone culture on mental health, so I was disappointed to find that Haidt’s book falls so far short of that. From a scientific perspective, the argument is a barrage of statistics, arranged to the tune of ‘correlation equals causation’. Given Haidt’s seniority in his field, this approach is surprisingly unsubtle, something which has already been heavily criticised by peer review. Numbers, it seems, do lie – or at least they can be easily curated to prove your point.

But even if we accept Haidt’s point – which is that rates of smart-phone use (particularly social media) and rates of young people being diagnosed with anxiety disorders have increased over the same time period – what can be done? Haidt’s solution is to ban young people from owning smartphones at all until the age of 14, and from using social media until the age of 16, or even better 18. In this way, owning and managing one’s own device and its access becomes a rite of passage into adulthood. But note: whilst parents are urged to implement these unyielding boundaries for their children’s device-habits, Haidt does not ask grown-ups to make any changes to their own. Adults can continue with their current norms of smartphone use, ostensibly because their brains are fully developed, and they therefore have the maturity to handle their own risk to mental health.

Smartphones are not aliens – they were designed by humans, and are willingly bought by humans, in response to the human need to communicate.

Of course, it does not suit Haidt’s argument to analyse why adult mental health is also seeing an increase in diagnosis of anxiety disorders. It may be true to say that rates are rising more quickly amongst young people, but there is still no consensus as to how much of that can be attributed to young people simply being better informed about mental health and more empowered to seek help than the generations before them. Noticeably, young people today have a language to talk about anxiety that simply didn’t exist when I was a teenager in the 1990s, and ironically enough, it is social media that has made that possible. Although suicide rates are on the rise, they are still quite significantly lower among young people than they are for those aged over 35, and it should be noted that a proven pathway to suicide prevention amongst young people is access to self-help via smartphone apps.

So whilst I am quite ready to believe that smartphone culture is one of many factors impacting the health and wellbeing of young people today, I think characterising smartphones as alien invaders, or as invasive parasites that have been selectively bred by Silicon Valley billionaires to infest the minds of our young people, seems to be a disingenuous response – and one that only serves to increase parental anxiety by implying that smartphones are sly, sentient beings, and out of our control.

Smartphones are not aliens – they were designed by humans, and are willingly bought by humans, in response to the human need to communicate and a perfectly natural human desire to seek out entertainment and culture. True, technology and software are developed by billionaires, and marketing and algorithms can influence our choices – but at the end of the day, any developer will tell you that products only ever evolve in response to what the market demands. Adults: we have the money in our pockets; we are the market.

As a more empathetic and intelligent generation, it seems they could probably teach us a few things about how to harness smartphone culture.

In other words, we (the adults) selectively bred these ‘aliens’ ourselves – and rather than try (and no doubt fail) to lock up our experiment in a lab (or, as Haidt suggests, a lockable phone-pouch) we, the adults, have more than enough agency to continue that process of developing smartphones into devices that meet needs and provide entertainment in the way that they were always meant to do. In his defence, Haidt does refer to this approach briefly, but still only with a view to making the phones be for ‘us’ (the adults) and not ‘them’ (the young people) by removing content that appeals to a younger audience. To me feels like we are victim shaming the youth of today for the fact that they have inherited a problem created by their parents.

One day when Jesus was teaching a crowd of followers, he advised them “Why do you look at the speck of sawdust in your brother’s eye and pay no attention to the plank in your own eye? How can you say to your brother, ‘Let me take the speck out of your eye,’ when all the time there is a plank in your own?” His point was about hypocrisy – it is far easier to judge someone else’s behaviour than it is to take responsibility for our own. Where did any of us last read or hear terrifying information about the decline in young people’s mental health? Was it on our smartphones?

Here are a few things that Haidt’s selection of statistics doesn’t say about the youth of today. They are the most compassionate and empathetic generation that we have seen for decades (Konrath et. al., 2023). They are able to wait longer for rewards than their parent’s generation (Protzko, 2020), they are also less lazy, less narcissistic, more cooperative and more intelligent (Kriegel, 2016). In addition, whilst obvious damage is done by ‘filters’ on Instagram photos, making some young people strive for unattainable standards of beauty, it was the previous generation of smartphone users who began this trend, and it is the current generation of young people who can be credited with the #nofilter #nomakeup countertrends. This same generation is now fuelling the rise of insurgent social media sites such as Bereal, which emphasise the importance of authentic photos and meaningful connection with friends online.

Overall, perhaps instead of restricting and controlling our young people’s online lives, as Haidt would have us do, we ought to be talking to them? As a more empathetic and intelligent generation, it seems they could probably teach us a few things about how to harness smartphone culture and develop it towards solutions to the problems that we ourselves created.
