In xkcd’s What If?, the scenario of human extinction is explored, shedding light on the fate of artificial sources of light if left untended. The thought of a world without humans is unsettling, but the comic poses an intriguing question: how long would it take for the last artificial light to flicker out if no one is around to maintain electrical systems or change light bulbs? The answer may surprise you, as different power sources have varying lifespans once humans are no longer in the picture.
As we delve deeper into this thought experiment, we realize that the impact of human absence on technology is profound. From the quick shutdown of power plants to the gradual dimming of solar-powered devices, the fate of artificial light sources is a fascinating glimpse into a world devoid of human intervention. Considering the intricate web of electricity grids and power sources that keep our lights on, it’s both humbling and eerie to imagine a future where these systems operate in silence, devoid of human touch.
Moreover, the longevity of certain power sources in this hypothetical scenario raises thought-provoking questions about resilience and sustainability. While some sources may sputter out within days or weeks without human maintenance, others could potentially endure for years, serving as a testament to human ingenuity and technological innovation. The stark contrast between the rapid demise of some power sources and the enduring glow of others paints a vivid picture of the fragility and resilience of our built environment in the face of human extinction.
In contemplating the gradual fading of artificial light in a world without humans, we are reminded of our interconnectedness with the technology that surrounds us. The flickering bulbs and dimming screens serve as silent witnesses to our presence on this planet, highlighting the ephemeral nature of our existence and the lasting imprint we leave behind. As we ponder the fate of artificial light in a post-human world, we are prompted to reflect on our stewardship of technology and the legacy we will ultimately leave for future generations.
