In computer science, artificial intelligence (AI), sometimes called machine intelligence, is intelligence demonstrated by machines, in contrast to the natural intelligence displayed by humans and animals. Colloquially, the term "artificial intelligence" is used to describe machines that mimic "cognitive" functions that humans associate with other human minds, such as "learning" and "problem solving".^[1]

As machines become increasingly capable, tasks considered to require "intelligence" are often removed from the definition of AI, a phenomenon known as the AI effect.^[2] A quip in Tesler's Theorem says "AI is whatever hasn't been done yet."^[3] optical character recognition is frequently excluded from things considered to be AI, having become a routine technology.^[4] Modern machine capabilities generally classified as AI include successfully understanding human speech,^[5] competing at the highest level in strategic game systems (such as chess and Go),^[6] autonomously operating cars, intelligent routing in content delivery networks, and military simulations.
