Civilisation as Innovation Engine: Why Simulating a Thousand Civilisations Changes Everything

Civilisation is an innovation engine. Every civilisation that has ever existed has produced innovations as a natural emergent property of intelligent agents interacting under pressure over time. Humanity has run exactly one civilisation: one trajectory through an infinite space of possible configurations. We propose that the ability to simulate civilisations of genuinely intelligent agents — made possible by LLM-based agentic AI — transforms civilisational development from a singular historical process into a repeatable, parallelisable, accelerable experiment. Running a thousand civilisations in parallel, each with different configurations, at speeds compressing millennia into days, produces a thousand different innovation trajectories — including emergent properties and structures that fall outside any existing human category. We present AgentCiv (agentciv.ai) as a proof of concept: a completed 70-tick simulation in which 12 agents with no social programming spontaneously produced 60 structures, 12 novel innovations, universal self-governance, and accelerating returns — each innovation expanding the adjacent possible and enabling the next faster. The vision extends to millions of agents in environments of arbitrary dimensionality, producing innovations that no single civilisation could generate alone. If civilisation is an innovation engine, simulation is an innovation amplifier of unlimited scale.
