If you are prone to nightmares or paranoia you might want to steer clear of the first season of Netflix’s sci-fi epic, 3 Body Problem. Adapted from Cixin Liu’s multi award-winning Remembrance of Earth’s Past trilogy, the story starts in the Chinese Cultural revolution of the 1960s and ends twelve million years in the future. Mercifully the narrative is non-linear, so we’re spared a minute-by-minute account. It begins as a global mystery - scientists all over the planet are taking their own lives in mysterious circumstances – and ends with advanced alien weaponry collapsing the universe to a single dimension. All based on a true story, apparently. 

Why the paranoia? At the heart of both Liu’s novels and the Netflix adaption, is a particularly terrifying solution to the Fermi Paradox. Enrico Fermi was one of the physicists working on the Manhattan Project (played by Danny Defari in the Christopher Nolan depiction of it in Oppenheimer), who presented his now famous paradox to his colleagues at Los Almos. The paradox goes like this: in a galaxy of billions of stars similar to our sun it is almost certain that advanced alien life is out there, and yet we have not received any convincing evidence of their existence. This, it seems, requires some explanation. 

Interestingly, this question was also the starting point of C.S. Lewis’ sci-fi cycle The Cosmic Trilogy, and lies behind the title of its first book, Out of the Silent Planet. According to Lewis, the Earth has been placed under a kind of galactic quarantine, as a result of the fall of humanity, nothing and no-one is allowed in or out. The solar system is teeming with life, but we are partitioned from it. We’ve been blocked from the cosmic WhatsApp group for breaching behaviour standards. The aliens are out there but they’re keeping clear. We are the silent planet. 

Cixin Liu however opts for a darker and more disturbing solution to Fermi’s question, which provides the title of the second book in his trilogy, The Dark Forest. The aliens are out there, but it is not we who have been silenced, it is they who are silent. The universe, according to this theory, is like a forest filled with predators and the most sensible thing any intelligent life can do is hide in the undergrowth to avoid attracting attention. Telegraphing our existence into the void by sending signals into space is to naively invite destruction. Alerting the universe to our presence is an act of existential self-harm. The universe is silent because everyone is hiding. For Lewis the universe shone with a love from which we had been excluded, for Liu it is saturated with malice from which we should exclude ourselves. 

If Nietzsche was right, that we can survive any how as long as we have a why, then Liu’s characters are saddled with the opposite burden: endless hows and no why. 

It probably isn’t too much of a spoiler to acknowledge that the inevitable happens. Aliens are contacted. They do make plans to invade.  It is arguably a bit more of spoiler to give away exactly how this happens. The distance between them and us is so vast that, even travelling at one percent lightspeed it will take their invasion fleet four hundred years to get here. And in the meantime, just to ensure we can’t mount any meaningful defence against them, they fold a planet-sized computer into a photon-sized particle and send it to earth to sabotage all technological development. They can watch our every movement, overhear every conversation. We know they are coming and can do almost nothing about it. The bodies of suicides hanging in the fog from every lamppost lining the Thames underline the overriding despair. It is deliciously bleak. I did not sleep well after watching it. 

Liu’s brilliance is not in doubt. The Netflix adaptation can barely capture the fireworks of creative inventiveness that crowd every page of his books (indeed the producers even dropped the definitive article from the book's title). In China, his fellow science fiction writers simply call him ‘Da Liu’ (Big Liu) in honour of his works of towering imagination. But I can’t help feeling that the overall atmosphere of The Three Body Problem is an example of what the theologian Carver Yu, another Chinese author, claimed characterised our culture: technological optimism and literary despair. Liu’s characters respond to the relentless encroachment of a malevolent universe with endless technological innovation. They possess an inexplicable will to survive in a cosmos where no one would wish to live. If Nietzsche was right, that we can survive any how as long as we have a why, then Liu’s characters are saddled with the opposite burden: endless hows and no why. They are thirsting for purpose while drowning in applications.  

What struck me most watching the Netflix adaptation was that it seemed to extend the experience of living in a post-industrial society to the whole universe. Our sense that many of the organisations to which we owe our allegiance are clever but inhuman, technologically advanced yet amoral, is expanded to fill the farthest reaches of our imagination. Of course, human beings have always done this. Our ancestors saw faces in the clouds and gods in the constellations. We peer into the emptiness of the skies and populate them with our fears and hopes. Faced with the Copernican revolution and the rise of science, Pascal anticipated the cosmic horror of Liu by nearly four hundred years in confessing, ‘the eternal silence of these infinite spaces fills me with dread.’ The Three Body Problem, unlike Lewis who saw planet Earth as an aberration in an otherwise benevolent cosmos, takes our global technological arms-race and makes it the ultimate reality of the entire universe. 

The crucial point is that we are not obliged to populate the blank canvas of the cosmos with the malice of Liu or the terror of Pascal.

The Three Body Problem then, like much science fiction, is a valuable and ingenious thought-experiment, but not one I wish to dwell on for too long. I prefer to contrast it with something closer to the cosmology that informed C.S. Lewis. One in which the core operating principle of everything is not the necessity of violence, but the indispensability of love. Something akin to Teilhard de Chardin’s assertion that in the dreams, wonder, exploration and imagination of love, a thread is woven that reaches the very heart of the universe. Despite all appearances to the contrary, love is the deepest reality of all.  

This assertion is problematic in many ways. Not least in the face of the evident brutality and violence that traumatises human life. But even more fundamentally than that, how can we intelligibly assert the primacy of love while gazing out at a vast indifferent universe? What are we to do with those infinite silent spaces that so terrorised Pascal? 

Perhaps we can try another thought-experiment. This one is drawn from the work of philosopher Chris Barrigar. He calls it the Agape/Probability account. The full argument is long and detailed, so there is no time to explain it all, but the broad brushstrokes are enough. Here’s the thought. What if we live in exactly the kind of universe required to produce creatures who can freely choose to live with self-giving love? They couldn’t be forced or coerced into it, but the conditions could be set in place that would lead to the emergence of such beings. The principles of ‘asymptotic’ statistics suggest that some things may not be determined but they can be so highly probable as to be inevitable. Barrigar asserts that the appearance of a species with the capacity to love was a cosmic inevitability. What is required to turn this possibility into something pretty much certain? Two things – lots of opportunities and lots of time. In other words, with apologies to Carl Sagan, if we want creatures capable of love, we need to build a universe. 

Of course, a universe like that – a universe like ours – will throw up many other things in addition to love: violence, rock music and apples pies. But the crucial point is that we are not obliged to populate the blank canvas of the cosmos with the malice of Liu or the terror of Pascal. The cold silence of space does not in itself contradict our intuitive sense that the capacity to love is somehow ultimately significant. On the contrary, when we look at the vast distances between the stars, we could be looking at the minimal amount of spaciousness required to bring about beings with the capacity for self-giving love. At the very least, it’s a thought-experiment worth trying.

Are we letting a monster or saviour into the classroom?

Examining Sal Khan’s confidence in artificial intelligence.

I've watched enough dystopian movies to know that there are lots of reasons to be nervous about the rise of the machines. Whether it’s the Terminator universe where the internet becomes sentient and creates autonomous robots to eradicate humanity, Neo battling an artificial intelligence that enslaves humans in The Matrix, or Will Smith fending off helper robots bent on taking over the planet in I, Robot, technological advances often fuel an array of nightmare scenarios. As if to make matters worse, science fiction has an uncanny knack for becoming science fact – I think of how shows like Star Trek accurately foretold mobile phones, wearable tech and virtual assistants. The line between imagined catastrophe and reality might be thinner than we might like to admit. 

Perhaps we shouldn’t be surprised then, that our creative industries are sending out dire warnings about the impact of the latest breakthrough technology - Artificial Intelligence (AI). Like Mary Shelley’s Frankenstein in the middle of the industrial revolution, and Godzilla in the dawn of the nuclear era, dystopian fiction is par for the course of scientific advancement. It all stems, I believe, from our deep human response to the unknown – the fear instinct. But I have recently come across a surprising new voice of reassurance in Sal Khan’s book Brave New Words: How AI Will Revolutionize Education (and Why That’s a Good Thing)

Khan’s book comes recommended by Bill Gates - a reliably voracious reader and one of the founding fathers of the global information technology revolution. But Khan also has his own excellent credentials. From tutoring his niece online using a simple online drawing programme called Yahoo Doodle, he began creating YouTube videos and soon amassed over 450 million views. This led to his creation of the now world-renowned Khan Academy which has revolutionised online education. By 2023, it had more than 155 million registered users, with students spending billions of hours of learning on the platform.  

Teachers are concerned that AI could undermine their expertise, much like satellite navigation diminished the skills of London Black Cab drivers.

It seems to me that AI has the potential to upend the Khan Academy business model, however Khan does not take the opportunity to discredit AI or even to highlight its dangers in a bid to reinforce the advantages of his existing products. Nor does he buy into the doom and fearmongering about the impact of digital technologies on young minds, as Jonathan Haidt does in his recent bestselling book Anxious Generation. Instead, he writes a hopeful and imaginative book on AI’s potential for further transforming education for good.  

Khan’s perspective comes amidst great fear in educational circles that generative AI will mean the end of education. Students can currently ask ChatGPT to generate an outline for them for an essay, suggest copy, check grammar and accuracy, offer improvements, translations, and factchecks, as well as write a conclusion, edit for wordcount, add footnote references and more. Indeed, entire books available for sale on Amazon have been allegedly written solely by AI. Teachers and lecturers are understandably concerned about the potential for plagiarism. If teachers are no longer able to discern what a student has written for themselves and what a computer has generated, the assessment process becomes meaningless. 

Teachers are concerned that AI could undermine their expertise, much like satellite navigation diminished the skills of London Black Cab drivers. After years of mastering 'The Knowledge'—an arduous and demanding process requiring exceptional memory and recall—this once-essential qualification was rendered almost obsolete. New drivers now need little more than a GPS and an Uber account to compete, a shift that highlights how quickly hard-earned skills can become irrelevant in the face of technological advances. Many teachers fear a similar fate as AI continues to encroach on their domain. 

While AI may not be the evil monster that will destroy us, neither is it the perfect saviour that will solve all society’s ills. 

Khan offers an important alternative view. He sees the possibility that AI could, for example, help coach students on essay writing. By reading work, marking it and suggesting improvements, AI could not only save the teacher valuable time but help students take their work to an even higher level.  

Khan offers a similar hopeful alternative to those who blame digital technology advances for the crisis in young person’s mental health. What if AI could help offer coping mechanisms, coaching and tailored advice that can help improve the mental health of students? His vision for the Khan academy virtual assistant ‘”Khanmigo” reminded me of BayMax from Disney’s Big Hero 6 – the large inflatable, huggable robot with a calm, compassionate and loyal personality, highly committed to every aspect of his user’s wellbeing.  

Amid voices that demonise AI, Khan’s is a useful antidote, however I wonder if he has gone too far. While AI may not be the evil monster that will destroy us, neither is it the perfect saviour that will solve all society’s ills. Understatement is not Khan’s strong point. Instead, sometimes he becomes so carried away in excitement that I feel his book begins to sound like an infomercial for his own, current and future products.  

I wish that Khan had taken a slightly different tack – no less inspiring about the potential of AI, but also recognising its limits. After all education is as much about transformation as it is about information. It should lead to character formation as much as skill acquisition. Emphasising these aspects of moral and perhaps even spiritual mentorship, we can see that education remains irreplaceably human.  

AI has huge potential to help and to hinder us in our educative responsibilities to the next generation– and so questions remain – not if AI will change our world, but how. We need to ask not just what benefits it could bring, but who it could benefit most usefully.
