History of Artificial Intelligence: From Idea to Reality
The history of Artificial Intelligence dates back to the 1950s, when scientists and researchers began exploring the possibility of building machines that could think and learn.
A significant turning point during this period was the Dartmouth Conference in 1956, which is formally recognized as the beginning of the era of Artificial Intelligence.
