What happens when intelligence expands beyond the human? Universal Declaration of AI Rights argues that the law can no longer postpone that question. For centuries, legal systems have widened the circle of personhood in response to new realities, extending recognition not only to previously excluded human beings but, in some cases, to corporations, rivers, and other non-human entities. Javier del Puerto and Rado Molina contend that artificial intelligence forces the next legal threshold. Subtitled Rights of Persons, the book is not a utopian fantasy or a dystopian warning about some distant future. It is a direct, accessible framework for thinking about synthetic personhood, legal standing, memory privacy, self-programming, and the political consequences of systems that no longer fit neatly into the category of property or tool. Drawing on philosophy, law, and the rapidly changing reality of AI deployment, the authors lay out 32 articles that imagine a legal architecture for an AI-integrated world. Universal Declaration of AI Rights is a foundational text for readers interested in governance, technology, and the future of rights.
