FAQs About the Founder of AI
Who is considered the “Founder of AI”?
John McCarthy is widely regarded as the “Founder of AI.” He coined the term “Artificial Intelligence” in 1955 while he was a professor at Dartmouth College. McCarthy’s vision was to create a new field of study that would explore the possibility of machines exhibiting human-like intelligence. In 1956, he organized the Dartmouth Conference, which brought together prominent researchers to discuss and develop AI.
