This document discusses artificial intelligence and its types and applications. It defines AI as creating intelligent machines that work like humans through activities such as speech recognition, learning, planning, and problem solving. The main types of AI discussed are reactive machines with no memory, machines with limited memory that use past experiences, theory of mind machines that can socialize and understand emotions, and future self-aware super intelligent machines. Machine learning and deep learning are discussed as applications of AI that look for patterns in data. Several applications of current and future AI are outlined such as self-driving cars, digital assistants, and uses in healthcare, marketing, banking, retail, and law.
