Artificial Intelligence (AI) is a broad field of computer science focused on creating systems that can perform tasks that typically require human intelligence. This can include tasks such as learning, problem-solving, understanding natural language, and perceiving and interacting with the environment. AI technologies can range from highly specialized systems, such as image recognition algorithms, to more general applications, such as virtual assistants or autonomous vehicles.

In the context of your question, it's important to note that AI is not inherently good or bad; its impact depends on how it's designed, deployed, and controlled. While the popular culture often portrays extreme scenarios like those found in "WALL-E" and "Terminator," the reality of AI a wide and diverse spectrum of applications, from helpful and beneficial to potentially harmful if not carefully managed.
