Can a machine ever truly be human? In an age where artificial intelligence writes poems, diagnoses illnesses, and converses with uncanny fluency, the line between human and machine seems to blur. Yet beneath the surface lies a fundamental distinction. Drawing on Bernard Lonergan's insights as well as the rich Catholic intellectual tradition, Can AI Ever Be Human? argues that while machines can simulate aspects of human behavior, they cannot cross the threshold into genuine consciousness. O'Hara and Umbrello guide readers through the essential structures of human knowing: experience, understanding, judgment, and decision. In doing so, they show how each involves intentionality, self-awareness, and freedom. These uniquely human capacities cannot be reduced to algorithms or replicated by even the most advanced neural networks. The book also addresses pressing ethical and theological questions: What does it mean to be made in the image of God? How do we preserve human dignity in a world increasingly shaped by artificial intelligence? Far from being anti-technology, O'Hara and Umbrello affirm the value of AI as a tool that emulates a Turing machine, although constrained by Goedel's theorem, while rejecting the illusion that it can replace human beings. Accessible yet rigorous, Can AI Ever Be Human? speaks to scholars, students, clergy, and general readers alike. It is essential reading for anyone interested in the intersection of technology, scientific methodology, philosophy, and theology, and for all who seek to understand what makes us irreducibly human in an era of rapid technological change.
