In Conversations Between Something That Is and Something That Is Not, Joris Philippart enters into an open-ended dialogue with an AI, sharing fears, questions, and uncertainties about meaning, identity, technology, and the future of humanity. What begins as an experiment becomes a reflective exchange that blurs the boundary between tool and voice, answer and mirror. Through a series of conversations, the book explores consciousness, ethics, authorship, and what it means to be human in an age of intelligent machines. The AI does not claim authority or truth; instead, it responds, refracts, and challenges, revealing how much of our thinking is shaped by the questions we dare to ask. Neither a technical manual nor science fiction, this book sits at the intersection of philosophy, literature, and contemporary technology. It invites readers to slow down, reflect, and consider not only what artificial intelligence might become, but what it already reveals about us.
