I think that “scientific and policy knowledge that no one knows at birth and no one could discover by themself over a lifetime” is absolutely compatible with the hypothesis I outlined, even in its most naive form. If humanity’s progress is episodic RL where each human life is an episode, then of course each human uses the knowledge accumulated by previous humans. This is the whole idea of a learning algorithm in this setting.

If RL is using human lives as episodes then humans should already be born with the relevant knowledge. There would be no need for history since all learning is encoded in the policy. History isn’t RL; it’s data summarization, model building, and intertemporal communication.

This seems to be interpreting the analogy too literally. Humans are not born with the knowledge, but they acquire the knowledge through some protocol that is designed to be much easier than rediscovering it. Moreover, by “reinforcement learning” I don’t mean the same type of algorithms used for RL today, I only mean that the performance guarantee this process satisfies is of a certain form.
