Here’s my stab at rephrasing this argument without reference to IB. Would appreciate corrections, and any pointers on where you think the IB formalism adds to the pre-theoretic intuitions:
At some point imitation will progress to the point where models use information about the world to infer properties of the thing they’re trying to imitate (humans) -- e.g. human brains were selected under some energy efficiency pressure, and so have certain properties. The relationship between “things humans are observed to say/respond to” to “how the world works” is extremely complex. Imitation-downstream-of-optimization is simpler. What’s more, imitation-downstream-of-optimization can be used to model (some of) the same things the brain-in-world strategy can. A speculative example: a model learns that humans use a bunch of different reasoning strategies (deductive reasoning, visual-memory search, analogizing...) and does a search over these strategies to see which one best fits the current context. This optimization-to-find-imitation is simpler than learning the evolutionary/cultural/educational world model which explains why the human uses one strategy over another in a given context.
