Artificial intelligence has progressed significantly from its earliest concepts in ancient Greece. Key developments include Turing's work in the 1930s, the coining of the term "artificial intelligence" by John McCarthy in 1956, and IBM's Watson demonstrating success in healthcare and finance applications by applying natural language processing, hypothesis generation, and evidence-based learning. Current applications of AI include driverless vehicles, automated assembly lines, surgical robotics, and next-generation traffic control systems. However, fully simulating human-level intelligence through strong AI remains challenging, as scientists have yet to determine the "algorithms of thought" that underlie human cognition.
