The Technological Singularity

by Murray Shanahan

The last of these options raises the possibility of a whole virtual society of artificial intelligences living in a simulated environment. Liberated from the constraints of real biology and relieved of the need to compete for resources such as food and water, certain things become feasible for a virtual society that are not feasible for a society of agents who are confined to wetware. For example, given sufficient computing resources, a virtual society could operate at hyper-real speeds. Every millisecond that passed in the virtual world could be simulated in, say, one-tenth of a millisecond in the real world. If a society of AIs inhabiting such a virtual world were to work on improving themselves or on creating even more intelligent successors, then from the standpoint of the real world their progress would be duly accelerated. And if they were able to direct their technological expertise back out to the real world and help improve the computational substrate on which they depended, then the rate of this acceleration would in turn be accelerated. This is one route to a singularity-like scenario. The result would be explosive technological change, and the consequences would be unpredictable.
