{{Short description|Fictional supercomputer by Isaac Asimov}}Multivac is the name of a fictional supercomputer appearing in over a dozen science fiction stories by American writer Isaac Asimov. Asimov's depiction of Multivac, a mainframe computer accessible by terminal, originally by specialists using machine code and later by any user, and used for directing the global economy and humanity's development, has been seen as the defining conceptualization of the genre of computers for the period (1950s–1960s). Multivac has been described as the direct ancestor of HAL 9000.

Description

Like most of the technologies Asimov describes in his fiction, Multivac's exact specifications vary among appearances. In all cases, it is a government-run computer that answers questions posed using natural language,JOURNAL, Halbert, Martin, 1992, Recursive Reviews,weblink The Public-Access Computer Systems Review, 3, 21–28, and it is usually buried deep underground for security purposes. According to his autobiography In Memory Yet Green, Asimov coined the name in imitation of UNIVAC, an early mainframe computer. Asimov had assumed the name "Univac" denoted a computer with a single vacuum tube (it actually is an acronym for "Universal Automatic Computer"), and on the basis that a computer with many such tubes would be more powerful, called his fictional computer "Multivac".BOOK, Asimov, Isaac, In Memory Yet Green: The Autobiography of Isaac Asimov, 1920–1954, 1979, Doubleday, 9780385136792, 663, 4491369, Univac is an acronym for 'Universal Automatic Computer' but I somehow got it into my head, without thinking, that it meant 'uni-vac', or 'one vacuum tube.' From then on, I wrote a series of stories featuring a giant computer I called 'Multivac.', His later short story "The Last Question", however, expands the AC suffix to be "analog computer". However, Asimov never settles on a particular size for the computer (except for mentioning it is very large)BOOK, May, ((Andrew Verfasser)), Rockets and Ray Guns : the Sci-Fi Science of the Cold War, 2018, 978-3-319-89830-8, 1038746131, :86 or the supporting facilities around it. In the short story "Franchise" it is described as half a mile long (~800 meters) and three stories high, at least as far as the general public knows, while "All the Troubles of the World" states it fills all of Washington D.C.. There are frequent mentions of corridors and people inside Multivac. Unlike the artificial intelligences portrayed in his Robot series, Multivac's early interface is mechanized and impersonal, consisting of complex command consoles few humans can operate. In "The Last Question", Multivac is shown as having a life of many thousands of years, growing ever more enormous with each section of the story, which can explain its different reported sizes as occurring further down the internal timeline of the overarching story.BOOK, Computer sciences, 2002, Macmillan Reference, 9780028655697, Flynn, Roger R., 671558424, :20

Storylines

Multivac appeared in over a dozen science fiction stories by American writer Isaac Asimov, some of which have entered the popular imagination.BOOK, Pak, Chris, Science fiction and computing : essays on interlinked domains, 2011, McFarland & Co, 978-0-7864-4565-3, Ferro, David, Jefferson, 13–37, Computers in Science Fiction: Anxiety, 668182916, Swedlin, Eric G., BOOK, Goble, Neil, Asimov analyzed, 1972, Mirage, 254106640, {{Citation|last=Seising|first=Rudolf|title=Science Visions, Science Fiction and the Roots of Computational Intelligence|date=2013|work=Computational Intelligence in Intelligent Data Analysis|series=Studies in Computational Intelligence|volume=445|pages=123–150 |publisher=Springer |doi=10.1007/978-3-642-32378-2_9|isbn=978-3-642-32377-5}} In the early Multivac story, "Franchise", Multivac chooses a single "most representative" person from the population of the United States, whom the computer then interrogates to determine the country's overall orientation. All elected offices are then filled by the candidates the computer calculates as acceptable to the populace. Asimov wrote this story as the logical culmination – and/or possibly the reductio ad absurdum – of UNIVAC's ability to forecast election results from small samples.WEB, 2014-05-08, Voters can be influenced by voter advice websites, but they do not follow the guidance blindly,weblink 2020-08-11, Democratic Audit, en-GB, WEB, Data-driven democracy: Who decides?,weblink 2020-08-11, aecpa.es, es-ES, In possibly the most famous Multivac story, "The Last Question", two slightly drunken technicians ask Multivac if humanity can reverse the increase of entropy. Multivac fails, displaying the error message "INSUFFICIENT DATA FOR MEANINGFUL ANSWER". The story continues through many iterations of computer technology, each more powerful and ethereal than the last. Each of these computers is asked the question, and each returns the same response until finally the universe dies. At that point Multivac's final successor, the Cosmic AC (which exists entirely in hyperspace) has collected all the data it can, and so poses the question to itself. As the universe died, Cosmic AC drew all of humanity into hyperspace in order to preserve them until it could finally answer the Last Question. Ultimately, Cosmic AC did decipher the answer, announcing "Let there be light!" and essentially ascending to the state of the God of the Old Testament.{{Citation|last=Nahin|first=Paul J.|title=Computers as Gods|date=2014|work=Holy Sci-Fi!|series=Science and Fiction|pages=95–107 |publisher=Springer |doi=10.1007/978-1-4939-0618-5_5|isbn=978-1-4939-0617-8}} Asimov claimed this to be the favorite of his stories.WEB,weblink Frequently Asked Questions about Isaac Asimov, Of his own work, what were Asimov's favorite and least favorite novels?

Significance

Asimov's depiction of Multivac has been seen as the defining conceptualization of the genre of computers for the period, just as his development of robots defined a subsequent generation of thinking machines,BOOK, Warrick, Patricia S., The cybernetic imagination in science fiction, 1980, MIT Press, 0-262-23100-X, Science fiction images of computers and robots, 5831667, and Multivac has been described as the direct ancestor of HAL 9000. Though the technology initially depended on bulky vacuum tubes, the concept – that all information could be contained on computer(s) and accessed from a domestic terminal – constitutes an early reference to the possibility of the Internet (as in "Anniversary")."About MultiVAX".
