A story centered around one of the great geniuses of the modern age, the Hungarian polymath John von Neumann, tracing the uncanny circuit of his mind deep into our own time's most haunting dilemmas-- Johnny von Neumann was an enigma. As a young man, he stunned those around him with his monomaniacal pursuit of the unshakeable foundations of mathematics. But when his faith in this all-encompassing system crumbled, he began to put his prodigious intellect to use for those in power. As he designed unfathomable computer systems and aided the development of the atomic bomb, his work pushed increasingly into areas that were beyond human comprehension and control - and that threatened human destruction. In The Maniac, Benjamin Labatut braids fact with fiction in a scintillating journey to the very fringes of rational thought, right to the point where it tips over into chaos. Stretching back to early twentieth-century conflict over contradictions in physics and up to advances in artificial intelligence that outpace the human, this is a mind-bending story of the mad dreams of reason. In a scintillating mix of fact and fiction, The MANIAC tells of the dark foundations of our modern world and the nascent era of AI. At its core is John von Neumann, a titan of science who revolutionised fields from game theory to computer systems and helped develop the atomic bomb. As illness unmoored his mind, his work pushed further into areas beyond human comprehension and control. With dazzling mastery, Benjamín Labatut weaves von Neumann's story together with the crises in physics at the beginning of the twentieth century and humanity's showdown with artificial intelligence a hundred years later. Innovative and disquieting, this book plunges us into the most profound questions of humanity, where reason teeters on the brink of chaos.
