It defines AI as intelligence exhibited by machines, and notes the two main types are weak AI, which simulates human thought, and strong AI, which equals or surpasses human level intelligence. Key figures in AI history discussed include Alan Turing, the father of computer science, and John McCarthy who coined the term AI. Examples are given of current AI applications in areas like military, medicine, banking, cell phones, and toys/games. The future impact of AI and robotics on jobs is also addressed.
