This document provides an introduction to artificial intelligence, describing it as the development of computer systems that can perform tasks requiring human intelligence such as visual perception and decision-making. It distinguishes between weak AI, which can respond to specific situations but not think for itself, and strong AI, which could think and act like humans by learning from experiences. Examples of real-life AI applications are given such as self-driving cars and chatbots, while the benefits are said to include reducing risks to humans in areas like war, dangerous workspaces, and natural disasters or assisting with everyday tasks like cleaning and transportation.
