The Phenomenal Growth of Human Power (1500-Present)

Key Insight

The last 500 years have witnessed an unprecedented and phenomenal growth in human power, transforming the world beyond recognition for someone from the year 1500. This era saw the global Homo sapiens population increase fourteen-fold, from approximately 500 million to 7 billion. Economic production also surged dramatically, from an estimated $250 billion in 1500 to nearly $60 trillion today, a 240-fold expansion. Concurrently, human energy consumption escalated 115-fold, from about 13 trillion calories per day to 1500 trillion calories, reflecting a profound shift in human capabilities and resource utilization.

This rapid advancement is evident in stark comparisons between the past and present. A single modern battleship could effortlessly destroy entire pre-modern navies, and five modern freighters could carry all the cargo of the world's merchant fleets from Columbus's time. A contemporary computer possesses storage capacity exceeding all medieval codex books and scrolls, while a large modern bank holds more wealth than all premodern kingdoms combined. The simple, small cities of 1500, with their mud, wood, and straw buildings and dirt tracks, contrast sharply with today's towering metropolises.

Human mobility and scientific understanding also underwent radical transformations. Circumnavigating the globe, a three-year journey that cost Magellan's expedition most of its crew in 1522, is now achievable in just forty-eight hours for a middle-class individual. Humanity's reach extended into space, culminating in the 1969 moon landing, an evolutionary and cosmic feat. Furthermore, the discovery of microorganisms by Anton van Leeuwenhoek in 1674 opened up a new world, leading to the defeat of deadly diseases and the engineering of bacteria for medical and industrial applications, showcasing an immense increase in control over life's fundamental processes.
