Artificial intelligence (AI) is defined as making computers do tasks that require intelligence when done by humans. There are two main types of AI: weak AI, where machines act intelligently to accomplish specific tasks, and strong AI, where machines have general human-level intelligence. AI works using artificial neurons and logic-based rules. It has many applications in areas like finance, medicine, manufacturing, customer service, and gaming. While AI provides benefits like speed and accuracy, it also faces limitations such as a lack of common sense and difficulty handling emergencies. The future of AI is uncertain but technology improvements may allow it to become more human-like over time.
