This document discusses artificial intelligence and its applications. It defines AI as intelligence displayed by machines, and notes two categories of AI methods: symbolic AI and computational AI, which includes neural networks and fuzzy systems. The document then discusses various applications of AI in fields like finance, medicine, industries, telecommunications, robotics, and gaming. It provides examples of achievements in AI like self-driving cars and cancer diagnosis. The future of AI is discussed, with the possibility that the world may increasingly rely on artificial rather than natural intelligence.
