I suppose what I want to know is the answer to "What features of our universe make it possible for entities to learn?".
Which sounds remarkably similar to DeVliegendeHollander's question, perhaps with an implicit assumption that learning won't be present in many (most?) universes.
The fact that the universe is stable/regular enough to be predictable. Subject predictability is a necessary requirement for learning.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
