Readers with a background in the esoteric world of computers may be familiar with "logic gates." These are devices that apparently perform simple logical thought, in electronic form. For example, an "AND gate" produces an affirmative output only when both of its inputs are affirmative. Conversely, an "OR gate" produces an affirmative output when either
of its inputs is affirmative. For many decades computer designers have been hobbled by a limited choice of gates: AND, OR, NOT, NOR, and a few other simple types.
For as long as computers have existed, debate has raged among fatuologists
(those who study the future) over whether enormous numbers of the simple gates listed above, interconnected in some unknown pattern, will someday duplicate human thought.
Recently, however, researchers have been working to enlarge the 'vocabulary' beyond these simple gates. A group led by Professor Mandine Typhon at the University of Calabraxas reports successful implementation of SO, HOWEVER, BECAUSE, ALTHOUGH, WHATEVER and UH HUH gates in 0.1 micron BiCMOS technology.
