Society and technology had advanced as expected. They lived in the modern era of new technologies. Despite the advancements in technology, this particular civilization had never invented batteries. Not just electrical batteries, but any kind of container capable of housing fuel, chemicals, food, liquids. As a matter of fact, despite being one of the most advanced civilizations in the Galaxy, they had never invented or discovered containers for any kind of energy.
The result was that their planet was full of cables, pipes, tracks originating from all kinds of places and going to an even higher number of destinations, because all devices and systems, including telephones, water, trains, and so on, had to be connected to an energy source or to a resource provider at all times in order to function.
Having so many cables and other connectors all over the place was complete chaos. People would constantly trip over and fall, construction would constantly cause power outages because workers would accidentally disrupt some powerline, and on the telephone it was impossible to ever find the person you wanted to talk to because technicians could not make sense of the telephone network.
But this problem was not isolated to the telephone network. All the networks on the planet had grown in complexity to the point that nobody could make sense of them anymore. And if some part of the network became disconnected, engineers would simply attempt to add more edges to the network in order to reconnect the isolated part of the network, rather than trying to repair the broken links.
On the positive side, because everything was directly connected to some power source, this society did not waste resources given that energy sources produced exactly the amount of energy that was in demand. This rule applied not just to electronic systems but to all industries: there were no supermarkets and no restaurants so people had to eat directly from tree and animal farms, or fish from the seas and from the oceans, and drink directly from water streams and other sources of clean water, such as springs, and get dressed at cotton plantations.
Also, this society did not accumulate trash and other industrial by-products. They could not do so because not only they did not know and understand the concept of storage, they also did not know or understand what the word accumulate meant. Instead these by-products were immediately consumed by another industry or they were destroyed by means of vaporization, fission, and other destructive processes.
Computers in particular were interesting and quite peculiar because they did not have memory or a hard drive given that those were essentially energy containers, which had not been invented yet. As a result, computers were terrible at remembering things, a shortcoming that forced computer engineers to develop extremely fast processing units: since computers could not remember what they had computed previously, they had to perform the same calculations over and over again, many times repeatedly, and for this speed was a critical workaround.
One day in the middle of the night, an unfortunate soul had the misfortune of tripping yet again on a cable. At first, this may not seem like anything out of the ordinary, since people tripped on cables all day long. What he did not realize was that the mesh of planetary networks had grown so complex that a critical bottleneck had formed. And that bottleneck happened to be holding on by a thread, or better yet, by the strength of this isolated cable.
The weak cable did not sustain the fall of yet another trip and gave in, and as it became disconnected, so did all the other systems on the planet. One by one, systems started failing and shutting down. One by one, lights went out, factories stopped, traffic halted, telephone lines went dead, ventilation stopped breathing, and the background buzz slowly died down until all noise was completely replaced by natural sounds of birds chirping, trees shaking, winds blowing, and water streams flowing.
Immediately people scrambled to find the source of the problem so they could repair the network and bring the planetary machinery back online. But without any flashlights, or battery-packed powertools, or any kind of cordless tools, they never managed to find the root of the problem and fix it. Eventually people just gave up and hope in restoring this mechanical world was lost. But hope in life was never lost.
The day technology died was the day humanity reconnected with Nature. The planetary systems died and their buzz faded away, replaced by the symphony of wind rustling through leaves and birds chirping. From the cold gaze of distant space, the planet might have appeared lifeless, but in reality on its surface, a vibrant rebirth was unfolding. People were no longer tethered to glowing screens. Instead, they rediscovered a simpler, happier, truer life, a bond with Nature. And the tangled web of cables that once snagged at their feet was gone, never to trip anyone anymore till the dawn of time.
