This book is the second volume in the two-volume set Artificial Intelligence and Discourse . It explores how generative AI tools such as ChatGPT-3, ChatGPT-4, Gemini, and CoPilot are transforming human&machine interaction and communication across institutions and individuals in education, journalism, policy, and creative industries. With contributions from nine countries, it examines GenAI not just as a tool but as an active conversational partner shaping language, identity, and professional practice. The chapters analyse anthropomorphism, algorithmic bias, and the challenges of meaning-making in contexts ranging from classroom writing and resume design to political speechwriting and STEM creativity. Case studies reveal how AI reshapes agency, creativity, authority, and self-perception, while exposing potential risks of miscommunication, bias, and cultural erasure. Drawing on discourse analysis, linguistic pragmatics, digital humanities and rhetoric, the volume offers accessible, interdisciplinary perspectives for researchers, educators, and policymakers seeking to understand and critically engage with the cultural and communicative consequences of AI in everyday life.
