The Original HorsePower

For most of human history, horses were essential to how we moved, farmed, and built civilizations. They carried us across continents, powered economies, and shaped the rise of entire empires.

But today, that necessity has largely disappeared. Machines have replaced the roles horses once filled—yet the systems we built around them remain.

In this episode, we explore the evolution of the horse, its transformation through domestication, and the modern paradox it now occupies: no longer essential, but still expected to perform.

From racetracks to carriage rides, this is a reflection on tradition, utility, and what it means to rethink our relationship with animals in a world where we may no longer need them—but still choose to use them.
