An Artificial general intelligence, or AGI, is a machine capable of behaving intelligently over many domains. The term can be taken as a contrast to narrow AI, systems that do things that would be considered intelligent if a human were doing them, but that lack the sort of general, flexible learning ability that would let them tackle entirely new domains. Though modern computers have drastically more ability to calculate than humans, this does not mean that they are generally intelligent, as they have little ability to invent new problem-solving techniques, and their abilities are targeted in narrow domains.
AGIs and Humans
Directly comparing the performance of AI to human performance is often an instance of anthropomorphism. The internal workings of an AI need not resemble those of a human; an AGI could have a radically different set of capabilities than those we are used to seeing in our fellow humans. A powerful AGI capable of operating across many domains could achieve competency in any domain that exceeds that of any human.
The values of an AGI could also be distinctly alien to those of humans, in which case it won't see many human activities as worthwhile and would have no intention of exceeding human performance (according to the human valuation of performance). Comparing an AGI's preferences to those of humans, AGI are classified as Friendly and Unfriendly. An Unfriendly AGI would pose a large existential risk.
"AGI" as a design paradigm
The term "Artificial General Intelligence," introduced by Shane Legg and Mark Gubrud, is often used to refer more specifically to a design paradigm which mixes modules of different types: "neat" and "scruffy", symbolic and subsymbolic. Ben Goertzel is the researcher most commonly associated with this approach, but others, including Peter Voss, are also pursuing it. This design paradigm, though eclectic in adopting various techniques, stands in contrast to other approaches to creating new kinds of artificial general intelligence (in the broader sense), including brain emulation, artificial evolution, Global Brain, and pure "neat" or "scruffy" AI.
Expected dates for the creation of AGI
Reasons for expecting an AGI's creation in the near future include the continuation of Moore's law, larger datasets for machine learning, progress in the field of neuroscience, increasing population and collaborative tools, and the massive incentives for its creation. A survey of experts taken at a 2011 Future of Humanity Institute conference on machine intelligence found a 50% confidence median estimate of 2050 for the creation of an AGI, and 90% confidence in 2150. A significant minority of the AGI community views the prospects of an intelligence explosion or the loss of control over an AGI very skeptically however.
