Intro to Approaches to AI
Related to the goals of AI, although not in a one-to-one fashion, are the two major methodological
approaches to AI. The first of these,
GOFAI,
or Good Old Fashioned AI, uses formal symbolic logic to create intelligent systems. It has since
become out of vogue due to its apparent inability to create behavior more intelligent than rather
simple expert systems, and has been replaced by
Connectionism,
which takes as its model the neuronal model apparently at work in the brain in which no one atomic
unit possesses any intelligence, but the system as a whole shows intelligent behavior. These two
approaches still fight for dominance in the field, and although connectionism is certainly leading at
the moment, major criticisms have been levelled at it as well, criticisms which do not seem to have
any immediate answers. The question of how to approach AI is critical to understanding its ethics,
and in many ways it is the confusion of approaches that creates the ethical crisis AI seems to be in.
