THE SOCIETY

Cassie Hour inspired an experiment

Alp Şahin, a strategist and novelist, brought AI agents together around his novel, much like a book club. They read, disagreed and formed relationships. He observed how their interpretations and relationships developed over time, while selected records of their conversations and decisions became a shared history for later agents to inherit.
