Surfing the Cut: The Uncomputable Nature of Things (Hardcover) (ISBN-13: 9798901020739)

What if the universe can't be fully captured by our equations, algorithms, or philosophies-because the most important part of reality is uncomputable?

In Surfing the Cut: The Uncomputable Nature of Things, physicist and technologist Todd Hylton traces a two-decade search that began with a practical mission: understanding intelligence well enough to build truly intelligent machines. As a DARPA program manager who launched SyNAPSE, he discovered a deeper problem behind the engineering challenge: the widespread assumption that the world is computable.

Hylton argues that computationalism is not "wrong," but incomplete. It can describe what already exists, yet it cannot explain how new things come to exist-how novelty, purpose, and lived meaning arise. To bridge that gap, he introduces thermodynamicalism, a philosophy centered on the Cut: a spontaneous, multiscale discontinuity that drives the evolution of all things and unifies the fractures we live with-reason and emotion, brain and mind, science and religion, fate and free will.

Guided by ideas from computing, thermodynamics, quantum mechanics, life, and artificial intelligence, Surfing the Cut offers a fresh lens on the biggest questions: what intelligence is, why creation matters, and how to navigate a world increasingly dominated by algorithmic thinking. This book doesn't ask you to abandon science or spirit-it asks you to see how they fit together at the edge where things become.

Along the way, Hylton equips readers with a set of propositions and practical intuition for "surfing" the Cut-shifting between what can be measured and what can only be experienced. The final chapters extend thermodynamicalism into everyday concerns, from politics and business to morality and climate change, and introduce thermodynamic computing as a pathway beyond today's limits.

If you've ever felt that modern explanations leave out the very things that make life meaningful, Surfing the Cut offers a rigorous, imaginative framework to hold the whole picture-and a vocabulary for the mystery you already sense.
