Earth’s Technosphere: When Resource Strain Tests Civilization Endurance
A new arXiv study models Earth’s technosphere to probe how technologically advanced civilizations may collapse and recover. By running 10 Earth-originated scenarios with 200 simulations each over 1,000 years, the work highlights the ‘duty cycle’—the fraction of a civilization’s life it remains technologically active—and finds that resource depletion and the post-collapse recovery fraction are the key levers. Some futures never collapse, others fail quickly or repeatedly; technosignatures like CFCs vary by scenario. While Earth-centric and with acknowledged limits, the results suggest long-term fate hinges more on sociotechnical design and resource management than luck, with an interview of co-author Haqq-Misra linked.
