I want to know what learning actually is. Ideally you can provide a model that is compact and useful as possible, such that when I encounter the word 'learn' in daily life I could replace it with this model while seeing a complete set of unique gears within it such that I can look at a real-world learning system and see how its traits correspond to each of those parts.
What results from Tabooing it? What are its components? Is there a precise General Theory of Learning that underpins humans, animals, ML agents, or any other things that learn? If there are multiple constructs being pointed to with 'learn': what are the differences between systems that 'learn'? How many different kinds of 'learning' are there and what do they look like?
What isn't learning?
