In "The Science of Can and Can't," Chiara Marletto ushers us into the uncharted territory of counterfactuals, a groundbreaking approach poised to redefine our grasp of the physical world. With a narrative as elegant as the theories it explores, Marletto argues for the untapped potential of understanding not just what is, but what could be. This is a realm where the boundaries of current scientific inquiry—like the limits of quantum computing and the mysteries of artificial intelligence—can be expanded, offering solutions to today's most complex technological puzzles. Marletto's work is not just a map of what lies beyond the known; it is a promise of the marvels that await us in manipulating the fabric of reality itself. Beyond its potential to revolutionize technology, Marletto's vision invites us to a deeper contemplation of the universe. "The Science of Can and Can't" is more than a scientific manifesto; it is a philosophical odyssey into the possibilities that define our existence. Through the lens of counterfactual science, Marletto challenges us to rethink our understanding of the universe, not as a series of happenstances, but as a spectrum of infinite possibilities. This book is a beacon for the curious, the dreamers, and the pioneers, offering a new paradigm where the limits of knowledge are not barriers, but gateways to a more profound and abundant comprehension of the cosmos.
