These exchanges are rapidly becoming part of daily life--at work, in education, in healthcare, and in our social lives. But what, exactly, is happening when we "talk" with artificial intelligence? Do these systems understand us, or are we projecting understanding onto machines that in fact have none? Should we think of them as partners in communication, or as instruments that measure and model language?Communicating with AI: Philosophical Perspectives brings together leading philosophers to investigate these questions. The essays explore the foundations of meaning, the possibility of alien forms of thought and language, and the social and ethical challenges that arise when machines speak. Contributors debate whether LLM outputs have literal meaning, whether AI systems can be said to have beliefs or intentions, and how responsibility and trust should be understood in a world where machines produce speech acts. The volume also looks ahead to future architectures of artificial minds and the unsettling ethical possibilities of superintelligent systems reasoning about morality in ways that may diverge from human values. A central theme is methodological: how to think clearly about minds and communication without relying too heavily on human models. By comparing AI to animals, aliens, and even deities, the essays push readers to rethink what it means to understand and to be understood.Clear, rigorous, and deeply relevant, this volume offers an indispensable guide for anyone seeking to grasp the philosophical stakes of our emerging conversations with AI.
