The technological singularity is a hypothetical event in which artificial general intelligence (constituting, for example, intelligent computers, computer networks, or robots) would be capable of recursive self-improvement (progressively redesigning itself), or of autonomously building ever smarter and more powerful machines than itself, up to the point of a runaway effect—an intelligence explosion^[1][2]—that yields an intelligence surpassing all current human control or understanding. Because the capabilities of such a superintelligence may be impossible for a human to comprehend, the technological singularity is the point beyond which events may become unpredictable or even unfathomable to human intelligence.^[3]

Kurzweil predicts the singularity to occur around 2045^[6] whereas Vinge predicts some time before 2030.^[7] In 2012, Stuart Armstrong and Kaj Sotala published a study of artificial general intelligence (AGI) predictions by both experts and non-experts and found a wide range of predicted dates, with a median value of 2040.^[8] Discussing the level of uncertainty in AGI estimates, Armstrong stated at the 2012 Singularity Summit: "It's not fully formalized, but my current 80% estimate is something like five to 100 years."^[9]
