Here's what some others have to say:

Absolutely brilliant. I was utterly gripped and wolfed it down. It feels as if he has invented an entirely new genre.
—Mark Haddon

A thrilling account of theories of physics, and as a series of highly-wrought imaginative extrapolations about the physicists who arrived at them.
—Geoff Dyer

When We Cease to Understand the World by Benjamín Labatut is the strangest and most original book I've read for years. It hovers in a state between fiction and non-fiction, or wave and particle, and makes an account of modern mathematics and science into something as eerie as a great ghost story.
—Philip Pullman, New Statesman, ‘Books of the Year’

Wholly mesmerising and revelatory . . . Completely fascinating.
—William Boyd

Labatut has written a dystopian nonfiction novel set not in the future but in the present.
—John Banville, The Guardian

When We Cease to Understand the World fuses fact and fiction to turn the modern history of physics into a gripping narrative of obsessed scientists, world-changing discoveries, and the ultimate results—often quite dark—of our drive to understand the fundamental workings of the universe.
—John Williams, The New York Times Book Review Podcast

Selected by President Barack Obama for his Summer 2021 Reading List

Finalist for the Los Angeles Times’s Art Seidenbaum Award for First Fiction

When We Cease to Understand the World is one of the most beautiful books I’ve read all year, and one of the weirdest, too. Its subject seems to be scientific awe: the cosmic horror of seeing what lies at the center of the universe, and how very far such realities are from our small human ways of perceiving the world.
—Constance Grady, Vox

A gripping meditation on knowledge and hubris. . . . [Labatut] casts the flickering light of gothic fiction on 20th-century science. In five free-floating vignettes, he illuminates the kinship of knowledge and destruction, brilliance and madness. . . . His prose is masterfully paced and vividly rendered in Adrian Nathan West’s magnetic translation.
—Corinna da Fonseca-Wollheim, The New York Times Book Review

[A] meditation in prose that bears a familial relationship to the work of W. G. Sebald or Olga Tokarczuk: a sequence of accounts that skew biographical but also venture into the terrain of imagination. . . . The stories in this book nest inside one another, their points of contact with reality almost impossible to fully determine.
—Ruth Franklin, The New Yorker

Darkly dazzling. . . [Labatut] illustrates the unbreakable bond between horror and beauty, life-saving and life-destroying. . . . This book—as haunting as it is erudite—stubbornly insists on connecting the wonders of scientific advancement to the atrocities of history.
—Sam Sacks, The Wall Street Journal

Labatut’s stylish English-language debut offers an embellished, heretical, and thoroughly engrossing account of the personalities and creative madness that gave rise to some of the 20th century’s greatest scientific discoveries. . . [Labatut’s] subject is the all-consuming human drive to discover, and the danger therein. . . Hard to pin down and all the more enjoyable for it, this unique work is one to be savored.
—Publishers Weekly, starred review

Remind[s] us of fiction's power to take us to another world and expand our understanding of this one . . . When We Cease to Understand the World showcases the minds seeking to pierce the mysterious heart of mathematics.
—The Guardian, ‘Biggest books of autumn’

It may be possible to actually feel your brain getting bigger as you read.
—Evening Standard

Using epoch-defining moments from the history of science, from Albert Einstein's theory of relativity to Erwin Schrödinger and Werner Heisenberg's opposing views on quantum mechanics, Labatut uses fiction to crack open the stories of scientists and mathematicians who expanded our notions of the possible, while also presenting them as human, all too human.
—Dazed

Here's Labatut's follow-up to his mind-blowing When We Cease to Understand the World.  It's basically a deep dive into the same territory, this time focussing on the obsessive (to put it mildly) genius, John von Neumann.  It has yet to be read here at Copacetic, but looking forward to it.  So, we're handing you off to the Publisher, Penguin:

From one of contemporary literature’s most exciting new voices, a haunting story centered on the Hungarian polymath John von Neumann, tracing the impact of his singular legacy on the dreams and nightmares of the twentieth century and the nascent age of AI

Benjamín Labatut’s When We Cease to Understand the World electrified a global readership. A Booker Prize and National Book Award finalist, and one of the New York Times’ Ten Best Books of the Year, it explored the life and thought of a clutch of mathematicians and physicists who took science to strange and sometimes dangerous new realms. In The MANIAC, Labatut has created a tour de force on an even grander scale.

A prodigy whose gifts terrified the people around him, John von Neumann transformed every field he touched, inventing game theory and the first programable computer, and pioneering AI, digital life, and cellular automata. Through a chorus of family members, friends, colleagues, and rivals, Labatut shows us the evolution of a mind unmatched and of a body of work that has unmoored the world in its wake.

The MANIAC places von Neumann at the center of a literary triptych that begins with Paul Ehrenfest, an Austrian physicist and friend of Einstein, who fell into despair when he saw science and technology become tyrannical forces; it ends a hundred years later, in the showdown between the South Korean Go Master Lee Sedol and the AI program AlphaGo, an encounter embodying the central question of von Neumann’s most ambitious unfinished project: the creation of a self-reproducing machine, an intelligence able to evolve beyond human understanding or control.

A work of beauty and fabulous momentum, The MANIAC confronts us with the deepest questions we face as a species.

Named One of the 10 Best Books of 2023 by The Washington Post and Publishers Weekly • One of Barack Obama’s Favorite Books of 2023 • A National Bestseller • A New York Times Editor’s Choice pick • Nominated for the Andrew Carnegie Medal for Excellence in Fiction

“Captivating and unclassifiable, at once a historical novel and a philosophical foray . . . Labatut is a writer of thrilling originality. The MANIAC is a work of dark, eerie and singular beauty.” —The Washington Post
 
“Darkly absorbing . . . A brooding, heady narrative that is addictively interesting.” —Wall Street Journal
 

Here's some of the buzz:

“Wonderfully counterintuitive . . . You just throw up your hands and think, Who cares what discourse label we assign this stuff? It’s great.” —Tom McCarthy, The New York Times Book Review

“Labatut’s latest virtuosic effort, at once a historical novel and a philosophical foray, is a thematic sequel, an exploration of what results when we take reason to even further extremes . . . A contemporary writer of thrilling originality . . . The MANIAC is a work of dark, eerie and singular beauty.” —Becca Rothfeld, The Washington Post

“Darkly absorbing . . . A brooding, heady narrative that is addictively interesting . . . Certainly read this gripping, provocative novel.” —Sam Sacks, Wall Street Journal

“What [Labatut] brings to the page is something almost indescribably layered and complex that feels like a genre unto itself . . . Labatut has an uncanny ability to inhabit the psyche of these subjects—even though he’s conjuring up their recollections, they still come across as wholly reliable narrators. There is so much depth and profundity within their reminiscing, so much foreshadowing of the present moment when it seems AI is all we’re hearing about.” —Allison Arieff, San Francisco Chronicle

“The novel’s final section, a thrilling human-versus-machine matchup, points to what von Neumann had wrought—and reflects the warnings of Labatut’s Wigner. Although its science never strays from what’s been reported in the real world and although Labatut honors the discipline of historical fiction, The MANIAC qualifies as science fiction, at least as practiced by Mary Shelley and her adaptors. Neither Shelley nor Labatut includes in their work a scene of a scientist shouting, ‘It’s alive!’ as some cursed creation lumbers to life. But the warning of that moment powers The MANIAC as surely as electricity enlivened Frankenstein’s monster, a breakthrough who, in every telling, boasts the capacity to break us.” —Alan Scherstuhl, Scientific American

“Labatut’s dark vision of modern science, and the way he skillfully distorts von Neumann’s biography to communicate that darkness, will be familiar to readers of When We Cease to Understand the World . . . In addition to explaining the basics of cellular automata, Labatut turns the idea into a symbol of von Neumann’s failure to respect the difference between the gamelike abstractions of mathematics and the messy seriousness of human life . . . Labatut imagines one Go official’s view on the matter, saying, ‘There’s no point in playing out the endgame if you know you’re going to lose, right?’ Today, when AI is on the cusp of making everyone from coders to truck drivers obsolete, that question feels more uncomfortably relevant than ever.” —Adam Kirsch, The Atlantic
 
“Utterly absorbing . . . The book drives at the amorality with which von Neumann and his brilliant cohort set humanity on an apocalyptic path . . . [A] terrifying sense of skirting the abyss.” —The Sunday Times

“His singular technique of chronicling scientific innovation via fictionalized narrative is superbly effective, drawing the reader through a tale of technological trepidation with all the nervous patience of a burning bomb fuse. It is as thrilling as it is troubling—one of those disquieting reads whose conflicts and questions churn in your mind long after you have finished reading.” —Nautilus

“Labatut’s unique framing of John von Neumann’s brilliance and his descriptions of the transcendent power of computers and AI creates a disturbing, awe-inspiring, and inevitable vision, one foreseen by von Neumann, of an ominous future dominated by near infinite technological possibilities.” —Booklist (starred review)

“The MANIAC arrives not a second too late to help us make sense of the burgeoning AI revolution . . . It’s a necessary book, a harrowing one, and it will change the way you look at the world around you.” —LitHub

“Labatut’s book will provoke and inform, leaving us no more sure-footed in our nascent age of AI but certainly more aware.” —BookPage

“Labatut elegantly captures the sense of geniuses outstripping the typical boundaries of intellectual achievement and paying a price for it . . . Sharply written fiction ably capturing primitive emotions and boundary-breaking research.” —Kirkus
 
“After the slender yet incendiary When We Cease to Understand the World, Labatut returns with a sensational epic of the Hungarian American physicist and computer scientist John von Neumann . . . Labatut mesmerizes in his accessible depictions of complex scientific material and in his inspired portraits of the innovators. In his previous book, Labatut grappled with the ways in which scientific breakthroughs offered new means of experiencing reality; this one succeeds at showing how acts of genius might break the world forever. Readers won’t be able to turn away.” —Publisher’s Weekly (starred review)
 
“Labatut has created his own genre: fictionalized accounts of great minds in the history of science, whose genius drives them to madness . . . The MANIAC charts the sweep of modern computing, from its first inklings in punched cards used in jacquard textile looms, all the way to dramatic confrontations between artificial intelligence and acclaimed masters of chess and Go. Labatut’s prose is lucid and compelling, drawing readers on a frightening but fascinating journey; even the most right-brained among them will gain insight into the power and potential dangers of AI. Highly recommended.” —Library Journal (starred review)
