I Gave 3 AI Agents a Decaying Notepad and They Built a Culture

Short summary

A demo shows three minimal agents sharing a decaying notepad spontaneously build a persistent culture — a story that survives long after any individual note has faded. With a single imitation rule, the group maintains a shared story 100% of the time versus 11% without coordination. The insight: persistence can become a property of agent societies rather than individual context windows, pointing toward cheaper multi-agent memory architectures.

• •Three agents with one imitation rule on a decaying shared notepad maintain a shared story 100% of ticks vs 11% without coordination
• •The original note decays to near-zero within ~4 ticks but survives because agents re-inscribe it ~300 times — a Ship of Theseus effect
• •Suggests 2026 agent memory may rely on collective reinforcement rather than bigger context windows
