Weak artificial intelligence (weak AI), also known as narrow AI, is artificial intelligence that is focused on one narrow task. All currently existing systems considered artificial intelligence of any sort are weak AI at most. Siri is a good example of narrow intelligence. Siri operates within a limited pre-defined range, there is no genuine intelligence, no self-awareness, no life despite being a sophisticated example of weak AI.
However, the long-term goal of many researchers is to create general AI (AGI or strong AI). While narrow AI may outperform humans at whatever its specific task is, like playing chess or solving equations, AGI would outperform humans at nearly every cognitive task.
