"I don't have an e-mail address. As much as I admire the Internet I suffer literally agoraphobia, which in it's original sense means a fear of the marketplace. I do not want to receive three hundred e-mail messages per week from strangers…"
- William Gibson

Or earlier in this article Present Inefficiency in the Jury System in The Law Magazine, Or, Quarterly Review of Jurisprudence (1849):

While therefore we would desire our juries to be moulded after a higher standard, we do not mean that we want in them a superior degree of particular, partial or artificial intelligence, but a legal guarantee for greater general and judicial talent.

The Oxford English Dictionary lists the following proposal as the first use of the phrase "artificial intelligence":

"A Proposal for the Dartmouth Summer Research Project on Artificial Intelligence" authored by John McCarthy [credited with coining the phrase], Marvin Minsky, Nathaniel Rochester, and Claude E. Shannon.

The proposal aimed to study if machines could use language, form abstractions and concepts, solve kinds of problems now reserved for humans, and improve themselves.

The conference was actually held from June 19 to August 16, 1956, at Dartmouth College; widely recognized as the birth of AI as a field of study.
