As artificial intelligence and digital technologies reshape education, long-standing ideas about leadership, learning, and human development are being quietly transformed. This book offers a new way of understanding educational leadership by focusing on time, human growth, and the responsibilities of those who guide learning. Drawing on philosophy, education, and contemporary debates on AI, Alexander Gardner-McTaggart explores how attention, judgement, and childhood are changing under algorithmic conditions. At its centre is the concept of ontological stewardship, a new framework for understanding educational leadership under algorithmic conditions, supported by original concepts including ontological capture, pace compression, and temporal awareness. Written for educational leaders, researchers, and policymakers, the text provides a clear and thought-provoking framework for navigating uncertainty, supporting ethical decision-making, and sustaining meaningful educational practice in a changing world.
