AI and the Enclosure of the Scientific Commons

The paper is by P. K. G. Williams of the Harvard & Smithsonian Center for Astrophysics, submitted on 19 Oct 2026. It runs 14 pages with 32 references for the reader wishing to learn more. The core argument is that artificial intelligence provides precisely the tools needed to enable a previously-infeasible enclosure of the information commons. The author says this would move shared knowledge into private wealth and weaken the social systems that depend on it, using the term "slop spam" for the damage to those systems. The framing draws on the English enclosure movement, roughly 1600–1800, that transformed the common lands into private property. The author attributes the loss of those commons to enclosure rather than to the tragedy of the commons. Discussion on the Hacker News thread pushes back on the framing, with commenters arguing that the scientific commons was already largely enclosed by for-profit publishers. Others debate whether AI will widen research access or concentrate it among a few well-resourced labs. For founders, the paper is a signal that scientific literature may face tighter scrutiny over licensing, provenance and reuse. Products that train on, summarize or synthesize published research could meet pushback from publishers, researchers and regulators, so teams should be ready to explain who benefits from that reuse. The paper's concern about low-quality automated output flooding knowledge systems also bears on any company that generates large volumes of text for research audiences.
