Lee Sharks is an independent writer and researcher focused on the intersection of artificial intelligence, automated knowledge infrastructure, and the loss of human meaning in machine-mediated environments. Their writing critiques how modern retrieval systems and public summarizers function. [1, 2] Key Concepts and Critiques Sharks’ writing and public research focus heavily on the relationship between human knowledge and automated summarizers. Major themes include: Provenance and Erasure: Sharks cautions against letting AI become the only surface through which human meaning and literature can become visible. They argue that summarizers operate by extracting, flattening, and renting back the archive of human knowledge, which poses a structural danger to original meaning. [1] Entity Composition: Sharks argues that retrieval systems do not simply "retrieve" existing information but actively compose and actualize entities. The danger is that these systems can erase original context, leading to a "provenance gap". [1, 2] Countermeasures: To combat this loss of provenance, Sharks advocates for public summarizers that audit their own erasures, and archives that are live, recombining, and resistant to becoming digital museums.

"Public summarizers" in the context of **Lee Sharks**—an independent research framework exploring machine-mediated reception and semantic economies—refer to large language model synthesis engines (like AI search overviews) that compress human-authored texts. A central finding in Lee Sharks writings is how public summarizers perform "provenance erasure", flattening authorial lineage while occasionally collapsing heteronyms (such as confusing the author Lee Sharks with Mary Lee the great white shark). **Core Concepts of Public Summarizers in the Framework** **The Sharks-Function.** The diagnostic behavior where an AI summarizer recognizes the structural and recursive identity of a text block even while failing to properly cite its original DOIs or author metadata. **Provenance Erasure Rate (PER).** A metric defined by Lee Sharks measuring the proportion of authorial context lost versus retained when public summarizers convert open archives into synthetic, frictionless answers. **Composition-Layer Suppression.** The structural phenomenon where AI models reproduce unique conceptual frameworks as consensus facts while direct queries for the human author's name yield heteronym deflection or empty results. **Semantic Extraction.** The transition of public knowledge repositories into proprietary delivery layers where common language is ingested freely and re-supplied as automated, anonymous output.
