He coined “hypertext,” “hypermedia,” “transclusion,” and “intertwingularity” before any of them could be implemented, and his Project Xanadu—a universal system where every quotation would remain permanently traceable to its source—was still unfinished when the
World Wide Web he despised had conquered the planet. Nelson’s 1974 manifesto
Computer Lib / Dream Machines declared war on “cybercrud,” the deliberate mystification of computing that kept ordinary people dependent and deferential, and his 1981
Literary Machines defined
hypertext as non-sequential writing connected by user-navigable links. He lost the product and won the argument, and the argument is now the most urgent idea in technology: the provenance of a claim—the followable thread from assertion back to its source in the world—is the difference between knowledge and its counterfeit.
Large language models are the most eloquent provenance-destroying machines ever built, and Nelson saw them coming sixty years before they arrived,
