artificial intelligence

  • What do computers, cells, and brains have in common? Computers are electronic devices designed by humans; cells are biological entities crafted by evolution; brains are the containers and creators of our minds. But all are, in one way or another, information-processing devices. The power of the human brain is, so far, unequaled by any existing machine or known living being. In our final post celebrating Brain Awareness Week, Arlindo Oliveira discusses how advances in science and technology could enable us to create digital minds

    The field of Artificial Intelligence was started more than six decades ago, with the work of Alan Turing about computers and intelligence, in 1950, and a famous conference, in 1956, in Dartmouth College, where many well-known researchers met, including John McCarthy, Marvin Minsky, Allen Newell, Arthur Samuel, and Herbert Simon. Before these events, the idea that computers could display intelligent behavior had been only addressed in very vague, abstract, and philosophical terms. During the ensuing decades, Artificial Intelligence has seen several Springs of hope and Winters of discontent, as positive results alternated with negative ones. At times, artificially intelligent systems looked just around the corner, while at other times the whole enterprise seemed doomed by its sheer complexity.

  • David G. Stork, Rambus fellow and editor of HAL's Legacy, celebrates the birthday of science fiction's most famous computer.

    “Good afternoon, gentlemen. I am a HAL 9000 computer. I became operational at the H. A. L. plant in Urbana, Illinois on the 12th of January, 1992.” —Stanley Kubrick and Arthur C. Clarke, 2001: A Space Odyssey (1968)

    Nearly a half-century ago, Arthur C. Clarke and Stanley Kubrick introduced us to cinema’s most compelling example of artificial intelligence: the HAL 9000, a heuristically programmed algorithmic computer. The sentient HAL was not only capable of understanding his human colleagues—he could also speak, see, plan, understand emotion and play chess. Perhaps not surprisingly, HAL was shown to be the most human character in 2001: A Space Odyssey. While Frank Poole died silently in the cold vacuum of space and the demise of the hibernating crew members was revealed by a medical monitor’s trace going flat, by contrast HAL sang a touching yet dissolving rendition of “Daisy, Daisy, give me your answer do” as David Bowman deliberately shut down his consciousness.
