To model is to create an ontology; from an information theoretic pov they are necessarily reductionist toys; simplifications / “lossy compressions” of a greater complex reality. Skeletons, bones.
Or, they can be surfaces. Outsides-only Object oriented, tokens of a single type.
All models and ontologies create toy realities.
My knee-jerk reaction is the bold declaration that the toy reality is the only reality.
