Knowledge is external, acquired and unvalidated. It comes from books, papers, experts and language models. It may be useful, but it has not been tested against your specific reality.
Experience is learned through prediction and error, what we call PE-validated. Your machine makes a prediction, observes the outcome and measures the error. That prediction error becomes experience.
An LLM’s output is knowledge, potentially useful but unverified. What your machine learns through play is experience. Knowledge can inform hypotheses, but only experience updates the model.
Knowledge becomes experience only after PE validation. This solves a fundamental problem in AI: how to incorporate external information without being corrupted by it.
