Communicative AI by Mark Coeckelbergh and David J. Gunkel offers a deep and critical look at Large Language Models (LLMs), the powerful AI systems behind tools like ChatGPT. Rather than human-like thinkers, LLMs are probabilistic machines predicting word sequences through massive training data and complex algorithms, lacking true understanding or consciousness. The authors probe the ethical and legal dilemmas sparked by LLMs, including bias, factual errors, environmental costs, and issues of authorship and plagiarism. Framed by philosophical debates on truth and intelligence, the book calls on us to rethink core ideas about communication, agency, and what it means to be a “person” in an AI-driven world.
