Wikipedia
The memex (a portmanteau of "memory" and "index") is the name of the hypothetical proto-hypertext system that Vannevar Bush described in his 1945 The Atlantic Monthly article " As We May Think". Bush envisioned the memex as a device in which individuals would compress and store all of their books, records, and communications, "mechanized so that it may be consulted with exceeding speed and flexibility." The memex would provide an "enlarged intimate supplement to one's memory". The concept of the memex influenced the development of early hypertext systems (eventually leading to the creation of the World Wide Web) and personal knowledge base software. The hypothetical implementation depicted by Bush for the purpose of concrete illustration was based upon a document bookmark list of static microfilm pages, and lacked a true hypertext system where parts of pages would have internal structure beyond the common textual format. Early electronic hypertext systems were thus inspired by memex rather than modeled directly upon it.

So for twenty straight days Gonzales and the memex had explored data structures and their contents, testing nominal functional relationships against reality.
As a result, Gonzales and the memex had been like meat eaters stranded among vegetarians, unable to get their nourishment.
When they got home, Gonzales would tell the memex the latest news about Grossback, how the man had cracked at the last moment.
Whether Japanese, Koreans, Taiwanese, Hong Kong Chinese-Canadiansthey bought some corporations and merged with others, and Americans ended up working for General Motors Fanuc, Chrysler Mitsubishi, or Daewoo-DEC, and with their paychecks they bought Japanese memexes, Korean autos, Malaysian robotics.
For nearly a hundred years, the machine design community had pursued what they called artificial intelligence, and out of their efforts had grown memexes and tireless assistants of all sorts, gifted with knowledge and trained inference.
