A large share of civilization's relevant model content is available through descriptive representations, model fragments, formal constraints, and documentary evidence rather than as one explicit operational model. The next step is to reconstruct that operational structure. Description Requires Interpretation A standard may state what is required. A manual

Civilization is often said to accumulate knowledge. For practical action, much of that accumulation can be understood more concretely as the preservation of models, model fragments, and evidence from which models can be reconstructed. Writing Externalized Representations of Models Before durable writing, many practical models depended primarily on individual memory,

Large language models change Experience Capitalization because their learned statistical structure exposes regularities from enormous written corpora, while their ability to process targeted sources makes much more externalized model content computationally accessible for reconstruction. The Corpus Already Exists Humanity has spent centuries externalizing descriptions, constraints, fragments, and formal representations of

Many organizations appear highly automated because many individual operations are already performed by software. Orders are stored in one system. Payments are processed in another. Policies are written in documents. Inventory is tracked somewhere else. Customer requests arrive through email, chat, or support software. APIs expose actions that can be

For Experience Capitalization, the reusable operational value of experience lies primarily in the models that can be reconstructed from it. Episodes Do Not Scale A person may handle a thousand cases. Saving all thousand cases creates an archive. Another person can search it, but still has to decide which cases

Human experience is often described as if it were a special substance accumulated inside a person. For Experience Capitalization, a useful computational lens is to treat experience as repeated exposure to reality that gradually contributes to internal models for recognizing situations and choosing actions. This is a conceptual model of
