An "intelligence explosion" is what happens if a machine intelligence has fast, consistent returns on investing work into improving its own cognitive powers, over an extended period. This would most stereotypically happen because it became able to optimize its own cognitive software, but could also apply in the case of "invested cognitive power in seizing all the computing power on the Internet" or "invested cognitive power in cracking the protein folding problem and then built nanocomputers".

A strong version of this idea suggests that once the positive feedback starts to play a role, it will lead to a very dramatic leap in capability very quickly. This is known as a “hard takeoff.” In this scenario, technological progress drops into the characteristic timescale of transistors rather than human neurons, and the ascent rapidly surges upward and creates superintelligence (a mind orders of magnitude more powerful than a human's) before it hits physical limits. A hard takeoff is distinguished from a "soft takeoff" only by the speed with which said limits are reached.

Published arguments

Philosopher David Chalmers published a significant analysis of the Singularity, focusing on intelligence explosions, in Journal of Consciousness Studies. His analysis of how they could occur defends the likelihood of an intelligence explosion. He performed a very careful analysis of the main premises and arguments for the existence of the a singularity from an intelligence explosion. According to him, the main argument is:"

1. There will be AI (before long, absent defeaters).
2. If there is AI, there will be AI+ (soon after, absent defeaters).
3. If there is AI+, there will be AI++ (soon after, absent defeaters).

4. There will be AI++ (before too long, absent defeaters). "

He also discusses the nature of general intelligence, and possible obstacles to a singularity. A good deal of discussion is given to the dangers of an intelligence explosion, and Chalmers concludes that we must negotiate it very carefully by building the correct values into the initial AIs.

Luke Muehlhauser and Anna Salamon argue in Intelligence Explosion: Evidence and Import in detail that there is a substantial chance of an intelligence explosion within 100 years, and extremely critical in determining the future. They trace the implications of many types of upcoming technologies, and point out the feedback loop...
