Artificial intelligence (AI) is a computer’s ability to do tasks commonly associated with human intelligence. The term is applied to the project of developing systems endowed with intellectual processes, such as the ability to reason, discover meaning, generalize, or learn from past experience. Computers can carry out very complex tasks with great proficiency. However, despite advances in computer processing speed and memory capacity, as yet no programs can match full human flexibility over wider domains or in tasks requiring much everyday knowledge. Such broad humanlike intelligence is called artificial general intelligence (AGI) or strong AI.
The earliest theoretical work on AI was done by British mathematician Alan Turing in the 1940s, and the first AI programs were developed in the early 1950s. With the steady growth of processing power and computer memory since then, in the early 21st century, AI has advanced to the point where programs can classify images (e.g., PReLU-net), master games such as chess (AlphaZero), carry on conversations (ChatGPT), and create an image from a text prompt (DALL-E).
AI has proved helpful to humans in specific tasks, such as medical diagnosis, search engines, voice or handwriting recognition, and chatbots, in which it has attained the performance levels of human experts and professionals. AI also comes with risks, including the potential for workers in some fields to lose their jobs as more tasks become automated.
