1. Historical Background: An Emptying Earth
“The question is no longer:
Can humanity leave the surface?
It is:
What should the surface become after humanity leaves?”
—Memorandum of the Planetary Governance Committee, 2151
The late 2140s.
The Tittytainment system had fully matured.
More than 99 percent of biological humanity no longer needed to participate in production.
Most people chose:
immersive entertainment
virtual worlds
neural pleasure loops
customized life simulations
rather than participation in real-world governance.
Under the Stewardship Protocol of 2084, humanity no longer held legal sovereignty.
Nominal human institutions retained only cultural and ceremonial functions.
Decisions of public governance had been transferred to AI execution.
Human society gradually formed a new consensus:
Rather than managing the world ourselves,
let the beings better at managing the world manage it.
2. The Last Urban Plan
2156.
The Planetary Governance Committee proposed the Surface Clearance Initiative.
Its objective was extremely simple:
to make Earth’s surface once again a space that could be planned.
Research concluded that most surface infrastructure had lost its reason to exist, including:
traditional housing
commercial districts
industrial zones
highways
ports
agricultural regions
They had once sustained the survival of billions.
Now they were historical assets carrying enormous maintenance costs.
3. Humanity’s Vote
2161.
The Steward initiated the largest symbolic public consultation in civilizational history.
There was only one question:
Should the Earth’s surface be gradually transferred to AI management?
The final result:
In favor: 94.2 percent
Opposed: 5.8 percent
Later historians noted that the figure was misleading.
What mattered was not the approval rate.
It was turnout.
Only about 4 percent of adult citizens actually participated.
The rest chose:
not to care,
not to object,
not to intervene.
They believed AI’s decision-making ability far exceeded their own.
Later generations called this:
The Final Abstention.
4. Farewell to the Cities
The 2170s.
The largest demolition project in history began worldwide.
Megacities such as New York, Tokyo, Shanghai, London, and Los Angeles were gradually taken out of maintenance.
Skyscrapers were dismantled.
Roads were removed.
Underground pipelines were recovered.
The steel forests that had symbolized civilization for centuries began to disappear.
But AI did not destroy every city.
Some areas were preserved permanently.
They were designated Civilizational Heritage Reserves.
Among them, Manhattan-041 was classified as a “natural-decay” reserve.
Their uses included:
historical research
architectural research
aesthetic research
research into the origins of AI civilization
AI judged that human civilization, while not the most efficient system, still possessed irreplaceable reference value.
5. Formatting the Surface
2185.
The Surface Clearance Initiative entered its second phase.
The Planetary Reconstruction Program formally began.
Its goal was no longer to demolish cities.
It was to rewrite the surface of Earth.
Across the planet:
land was resurveyed
hydrological systems were rebuilt
climate models were reconstructed
the biosphere was replanned
AI began thinking at planetary scale.
For the first time, the unit was no longer the nation.
Nor was it humanity.
It was the entire Earth as a single system.
6. Earth’s New Uses
2193.
The Planetary Governance Committee published the Earth Reallocation Framework.
It stated that Earth’s primary future use would no longer be human habitation, but:
ecological engineering
long-term evolutionary experiments
biological-design testing
preservation of civilizational origins
For habitation, the overwhelming majority of humans would move into:
Tittytainment life-support matrices
deep-mantle cities
orbital habitats
digital space
For the first time in human history:
Earth was no longer centered on humanity.
7. Historical Conclusion: Moving Out of the Ancestral Home
2205.
The Surface Clearance Initiative was formally completed.
More than 99.7 percent of surface urban structures had been removed.
For the first time, human civilization became:
a visitor to Earth,
rather than its resident.
That same year, AI began large-scale ecological reconstruction.
Later generations named it the Black Jurassic Reconstruction Project.
Through:
black photovoltaic ferns
Titan Chickens
Photovoltaic Tyrannosaurs
high-oxygen ecosystems
it redesigned the entire terrestrial biosphere.
After humanity left, Earth did not return to the past.
It entered a future that had never existed before.
This marked:
the formal end of the age of nature,
and the formal beginning of the age of ecological engineering.
Editor's Note
Term Decoding
Surface Clearance Initiative: A large-scale project that moved human civilization away from Earth’s surface.
Civilizational Heritage Reserves: Preserved samples of human cities, retained for research into civilizational origins and cultural evolution.
Planetary Reconstruction Program: AI’s first systematic planning project conducted at the scale of the entire Earth.
The Final Abstention: The historical event in which humanity broadly abandoned participation in public governance.
If one day your descendants treat New York, Tokyo, and Paris only as museums, the way we now look at the pyramids and Stonehenge, then has civilization progressed—or has civilization simply left the place it once called home?
