the Hinge of History: Making sense a world in transition — climate, AI, end an order, and road ahead

For three generations, four quiet supports made the future feel legible. They are failing at once.We are living through something rarer than a crisis. For most of a century, a stable climate, a single power underwriting the rules, information slow enough to be checked, and economies on predictable curves quietly manufactured a world you could plan for. All four are now giving way together - and artificial intelligence is adding a new force beneath everything.The Hinge of History is a field guide to that transition. It is not a book of prophecy or of panic. It reads the present as a phase change; holds it against the great transitions that came before - the fall of Rome, the printing press, the 1930s - and against the serious fiction that rehearsed our futures, from Asimov to Octavia Butler; and then asks the only question that matters: where do we go from here, and what would it take to choose well?Clear-eyed, humane, and honest about what no one can know, it argues that the outcome is not dictated to us. It is chosen.
