It is an overarching computer science discipline that deals with making machines think like humans, having consciousness and the ability to adjust to the changing environment by taking decisions creatively all by themselves after learning, over time. AI isn't new, as a matter of fact it was coined in 1956 by Professor John McCarthy at Dartmouth. He gathered a group of mathematicians and scientists to see if machines could learn by way of trial and error to develop formal reasoning. The roots of AI however, can also be traced back to Alan Turing's work. Note: The aspect of AI that is related to the creative decision-making ability of machines is known as general AI or Human Level AI.
