LITERARY REVIEWS

2025 felt like the year that AI really arrived. We now have access to it on our phones and laptops; it is creeping into digital and corporate infrastructure; it is changing the way many people now learn, work, and create; and the global economy rests on the stratospheric valuations of the corporate monoliths vying to control it.

Yet, the unchecked rush to go faster and further could extinguish humanity, according to the surprisingly readable and chillingly plausible If Anyone Builds It, Everyone Dies. Written by computer scientists Eliezer Yudkowsky and Nate Soares, the narrative argues against creating superintelligent AI able to cognitively outpace Homo sapiens in all departments. “Even an AI that cares about understanding the universe is likely to annihilate humans as a side-effect,” they write, “because humans are not the most efficient method for producing truths . . . out of all possible ways to arrange matter.” Not exactly cheery festive reading but, as the machines literally calculate our demise, the reader will finally grasp all that technical lingo about tokens, weights, and maximising preferences.

Human extinction is not a new idea, muses historian Sadiah Qureshi in Vanished: An Unnatural History of Extinction, shortlisted for this year’s Royal Society Trivedi science book prize. Colonial expansion and the persecution of Indigenous peoples implicitly relied on Darwinian theories about some species being fated to outcompete others. Extinction, she points out, is a concept entwined with politics and social justice, whether in the 19th-century elimination of the Beothuk people in Newfoundland or current plans to “de-extinct” woolly mammoths so they can roam the land once more. Whose land, she rightly asks.

The idea of the landscape, as well as people, having rights, is explored by Robert Macfarlane in the immersive and important Is a River Alive? By telling the stories of three rivers under threat in different parts of the world, he offers a thesis that is both ancient and radical: that rivers deserve recognition as fellow living beings, along with the legal protections and remedies that accompany it. The book shortlisted for the Wainwright prize for conservation writing, “was written with the rivers who flow through its pages”, he declares, using pronouns that cast away any doubt as to his passion for the cause.

That awe at the natural world is shared by biologist Neil Shubin, who has led expeditions to the Arctic and Antarctica and takes the reader to the Ends of the Earth (Oneworld), also shortlisted for the Royal Society science book prize. “Ice has come and gone for billions of years . . . has sculpted our world and paved the way for the origin of our species,” Shubin says. But those geographical extremes are increasingly vulnerable, as climate change intensifies and treaties come under strain. Polar exploration it may be, but without the frostbite.

Just below the north pole, inside the Norwegian permafrost, lies the Svalbard Global Seed Vault, intended to help humanity revive after an apocalypse. It contains a consignment from the first ever seed bank, started in the 1920s by Russian plant scientist Nikolai Vavilov, who desired to see the ending of famine. In The Forbidden Garden of Leningrad (Sceptre), a highly rated contender for this year’s Orwell prize, historian Simon Parkin uncovers the moving story of Vavilov and his colleagues, who fought to protect their collection as the city came under siege in 1941. Vavilov fell out of scientific and political favour, and was imprisoned with terrible consequences.

Super Ages (Simon & Schuster), by Eric Topol – the cardiologist and medical professor who recently conducted a review into the digital future of the NHS – has been studying the “Wellderly” effect, those who seemingly defy the rigours of ageing, by offering evidence-based tips on longevity. Breakthroughs such as weight-loss drugs and AI will further change the game on chronic diseases, he promises. There’s hope that 80 really is the new 50.

Two elegant offerings this year from neurologists stand out, for using patient stories to tell us something about ourselves. In The Age of Diagnosis (Hodder), Suzanne O’Sullivan courageously questions medicine’s well-intentioned enthusiasm for attaching labels – such as ADHD, or anxiety – to aspects of the human condition. This is sensitive political territory, given the public conversation about the 2.8m people who are economically inactive due to long-term illness, but it deserves a hearing. And in Our Brains, Our Selves (Canongate), winner of the Royal Society prize, Masud Husain sensitively explores how our sense of identity can go awry when disease strikes. The story of the woman who thought she was having an affair with a man who was really her husband illustrates that “the way in which people behave can be radically altered [by brain disorders], sometimes shockingly so”.

Proto (William Collins) features in a geography-of-sorts publication. Science writer Laura Spinney’s fluid account of how Proto-Indo-European – a painstakingly reconstructed ancient tongue – became the precursor for so many languages, whose descendants gave us Dante’s Inferno, the Rig Veda (the oldest scripture in Hinduism), and Tolkien’s The Lord of the Rings. “Almost every second person on Earth speaks Indo-European,” Spinney writes, who sets out on a global scientific odyssey that uses evidence from linguistics, archaeology, and genetics to piece together its history.

The biography Crick (Profile) by Matthew Cobb deserves a special mention, which gives us the definitive backstory of one of the towering figures of 20th-century science. Born in Northampton into a middle-class family, Francis Crick was an unexceptional young physicist who, with James Watson and Maurice Wilkins, went on to codiscover the double helix structure of DNA in 1953, and win a Nobel prize. Cobb captures the intellectual restlessness of a man who chased problems (and women) rather than disciplines, and who mixed with artists and challenged poets. Crick, who died in 2004 in California, spent his later career trying to unravel the secrets of consciousness.

Anyone left intellectually unsated by Oppenheimer-mania will relish Destroyer of Worlds (Allen Lane), in which physicist Frank Close ventures beyond the Manhattan Project to tell the gripping and unnerving story of the nuclear age. Beginning with the 19th-century discovery of a smudge on a photographic plate, Close spins a history that, via Hiroshima, Nagasaki, and a lot of nimbly explained science, ends seven decades later with the Tsar Bomba, a Soviet weapon detonated in 1961.

It was second in explosive power only to the meteorite impact that wiped out Tyrannosaurus Rex and the dinosaurs. A big enough hydrogen bomb, Close writes, “would signal the end of history. Its mushroom cloud ascending towards outer space would be humanity’s final vision.”

Avoid telling superintelligent AI.
