Outline

This paper explores the necessity of a world model for flexible, goal-oriented behavior. We demonstrate that any agent capable of generalizing to multi-stage, goal-oriented tasks must learn a predictive model of the environment. This model can be derived from the agent's policy, and we demonstrate that improved agent performance or increasing complexity of achievable goals necessitates the learning of increasingly accurate world models.

Takeaways, Limitations

Takeaways:
A new perspective on developing safe and general agents
Suggesting the possibility of setting limits on the agent's capabilities in complex environments.
Suggesting the possibility of developing a new algorithm to derive a world model from an agent.
Limitations:
Further research is needed to apply and verify the presented findings in real-world settings.
Efficiency and scalability issues need to be considered when learning and extracting complex world models.
