Abstract
This paper takes a sharp look at three innovations in artificial light, examining their impact on human productivity through history, and on our global society today. It posits that light technology has played a pivotal role in human productivity. From conversation around campfires, to handheld lighting technologies (such as candles, oil lamps, and other such crude— yet compact— lighting devices), to fiber-optic cables that carry information across oceans through the power of light— humanity’s productivity has been massively impacted by innovations in light technology.
