Broad Discussions of Artificial Intelligence
Exactly what the computer provides is the ability not to be rigid and unthinking but, rather, to behave conditionally. That is what it means to apply knowledge to action: It means to let the action taken reflect knowledge of the situation, to be sometimes this way, sometimes that, as appropriate...
In sum, technology can be controlled especially if it is saturated with intelligence to watch over how it goes, to keep accounts, to prevent errors, and to provide wisdom to each decision. --- Allen Newell, from Fairy Tales
If you are looking for an answer to the question What is Artificial Intelligence? and you only have a minute, then here's the definition the Association for the Advancement of Artificial Intelligence offers on its home page: "the scientific understanding of the mechanisms underlying thought and intelligent behavior and their embodiment in machines."
The National Academy of Science offers the following short summary of the field: "One of the great aspirations of computer science has been to understand and emulate capabilities that we recognize as expressive of intelligence in humans. Research has addressed tasks ranging from our sensory interactions with the world (vision, speech, locomotion) to the cognitive (analysis, game playing, problem solving). This quest to understand human intelligence in all its forms also stimulates research whose results propagate back into the rest of computer science—for example, lists, search, and machine learning." From Section 6: Achieving Intelligence of the 2004 report by the Computer Science and Telecommunications Board (CSTB) Computer Science: Reflections on the Field, Reflections from the Field (2004).
However, if you are fortunate enough to have more than a minute, then please get ready to embark upon an exciting journey exploring AI (but beware, it could last a lifetime) . . .
