This repository proposes Human-AI Hybrid Civilization (HAHC) and Future Networked Intelligence (FNI) as conceptual frameworks for understanding the long-term evolution of civilization under large-scale human-AI collaboration. The work introduces Brain-Unit Robots, External Cognitive Evolution, Human-AI Production Relations, and Civilization-Scale Intelligence Networks. Rather than focusing on AGI as a single superintelligent entity, the repository explores intelligence as an emerging property of interactions among humans, AI brain-units, institutions, memory systems, task graphs, action graphs, and collective learning processes.
