Abstract

Modern civilization is usually described as the most technologically advanced society in history. That statement is true, but incomplete. A civilization can possess superior tools while losing some of the capacities that make civilization sustainable: long-term planning, institutional memory, durable public works, intellectual synthesis, and the ability to preserve knowledge across generations.

This essay develops a hypothesis: the early twenty-first century may not be a simple age of progress or a simple age of decline, but a period in which technological capability continues to rise while civilizational capability becomes more fragile. The deeper cause may be a growing mismatch between the complexity of our systems and the cognitive architecture of human beings. We may be approaching what could be called a cognitive ceiling: not an absolute limit to intelligence, but a point at which unaided biological cognition, existing institutions, and current media environments struggle to manage the complexity they themselves have created.
