Artificial intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think and learn like humans. AI involves the development of algorithms and computer programs that can perform tasks that typically require human intelligence, such as visual perception, speech recognition, decision-making, and language translation. AI technologies include machine learning, natural language processing, robotics, and computer vision. AI has the potential to revolutionize many industries, including healthcare, finance, transportation, and manufacturing, by improving efficiency, accuracy, and decision-making. However, there are also concerns about the ethical and social implications of AI, such as job displacement, bias, and privacy.
