Artificial Intelligence (AI) refers to computer systems that mimic human intelligence. Its history spans decades, evolving from basic rule-based systems to advanced machine learning and neural networks. AI is categorized into Narrow AI (task-specific) and General AI (human-like abilities). Applications range from healthcare to finance, raising concerns about job displacement and ethical AI use. Future AI trends include deep learning and human-robot collaboration, with a focus on responsible development for societal benefit.
