John McCarthy AI pioneer dies

In 1956 John McCarthy organised the Dartmouth Summer Research Conference on Artificial Intelligence and thereby coined the term AI. He  invented the programming language LISP whilst at MIT and then went on the head the Stanford AI Lab (SAIL), which did groundbreaking work in robotics. Before these achievements he was a pioneer of timesharing networked computers. He foresaw the the power of computing in the cloud with processing becoming a utility you purchased as and when required; though during the thirty years of the PC revolution the ideas were largely ignored.
John McCarthy was 84.
