AI Takeoff is the process of an Artificial General Intelligence going from a certain threshold of capability (often discussed as "human-level") to being super-intelligent

and capable enough to control the fate of civilization. There has been much debate about whether AI takeoff is more likely to be slow vs fast, i.e., "soft" vs "hard".

AI takeoff is sometimes casually referred to as AI FOOM

.

Soft takeoff

A soft takeoff

refers to an AGI that would self-improve over a period of years or decades. This could be due to either the learning algorithm being too demanding for the hardware or because the AI relies on experiencing feedback from the real-world that would have to be played out in real-time. Possible methods that could deliver a soft takeoff, by slowly building on human-level intelligence, are Whole brain emulation, Biological Cognitive Enhancement, and software-based strong AGI [1]. By maintaining control of the AGI's ascent it should be easier for a Friendly AI to emerge.

Vernor Vinge, Hans Moravec and have all expressed the view that soft takeoff is preferable to a hard takeoff as it would be both safer and easier to engineer.

Hard takeoff

A hard takeoff (or an AI going "FOOM" [2]) refers to AGI expansion in a matter of minutes, days, or months. It is a fast, abruptly, local increase in capability. This scenario is widely considered much more precarious, as this involves an AGI rapidly ascending in power without human control. This may result in unexpected or undesired behavior (i.e. Unfriendly AI). It is one of the main ideas supporting the Intelligence explosion hypothesis.

The feasibility of hard takeoff has been addressed by Hugo de Garis, Eliezer Yudkowsky, Ben Goertzel, Nick Bostrom, and Michael Anissimov. It is widely agreed that a hard takeoff is something to be avoided due to the risks. Yudkowsky

points out several possibilities that would make a hard takeoff more likely than a soft takeoff such as the existence of large resources overhangs or the fact that small improvements seem to have a large impact in a mind's general intelligence (i.e.: the small genetic difference between humans and chimps lead to huge increases in capability) [3].
