http://en.wikipedia.org/wiki/Technological_singularity The technological singularity is a theoretical future point of unprecedented technological progress, caused in part by the ability of machines to improve themselves using artificial intelligence.[1] Statistician I. J. Good first wrote of an "intelligence explosion", suggesting that if machines could even slightly surpass human intellect, they could improve their own designs in ways unforeseen by their designers, and thus recursively augment themselves into far greater intelligences. The first such improvements might be small, but as the machine became more intelligent it would become better at becoming more intelligent, which could lead to an exponential and quite sudden growth in intelligence. Vernor Vinge later called this event "the Singularity" as an analogy between the breakdown of modern physics near a gravitational singularity and the drastic change in society he argues would occur following an intelligence explosion. In the 1980s, Vinge popularized the singularity in lectures, essays, and science fiction. More recently, some prominent technologists such as Bill Joy, founder of Sun Microsystems, voiced concern over the potential dangers of Vinge's singularity (Joy 2000). Following its introduction in Vinge's stories, particularly Marooned in Realtime and A Fire Upon the Deep, the singularity has also become a common plot element throughout science fiction. Others, most prominently Ray Kurzweil, define the singularity as a period of extremely rapid technological progress. Kurzweil argues such an event is implied by a long-term pattern of accelerating change that generalizes Moore's Law to technologies predating the integrated circuit and which he argues will continue to other technologies not yet invented. Critics of Kurzweil's interpretation consider it an example of static analysis, citing particular failures of the predictions of Moore's Law. Robin Hanson proposes that multiple "singularities" have occurred throughout history, dramatically affecting the growth rate of the economy. Like the agricultural and industrial revolutions of the past, the technological singularity would increase economic growth between 60 and 250 times. An innovation which allowed a replacement for virtually all human labor could trigger this singularity. Critics note that proponents of the "singularity" tend to ignore all of the negative impacts of technology, only focusing on the positive effects. The singularity also draws criticism from anarcho-primitivism and environmentalism advocates.

Since the design of machines is one of these intellectual activities, an ultraintelligent machine could design even better machines; there would then unquestionably be an ‘intelligence explosion,’ and the intelligence of man would be left far behind. Thus the first ultraintelligent machine is the last invention that man need ever make. ” Mathematician and author Vernor Vinge greatly popularized Good’s notion of an intelligence explosion in the 1980s, calling the creation of the first ultraintelligent machine the Singularity. Vinge first addressed the topic in print in the January 1983 issue of Omni magazine. Vinge (1993) contains the oft-quoted statement, "Within thirty years, we will have the technological means to create superhuman intelligence. Shortly thereafter, the human era will be ended." Vinge refines his estimate of the time scales involved, adding, "I'll be surprised if this event occurs before 2005 or after 2030." Vinge continues by predicting that superhuman intelligences, however created, will be able to enhance their own minds faster than the humans that created them. "When greater-than-human intelligence drives progress," Vinge writes, "that progress will be much more rapid." This feedback loop of self-improving intelligence, he predicts, will cause large amounts of technological progress within a short period of time. Most proposed methods for creating smarter-than-human or transhuman minds fall into one of two categories: intelligence amplification of human brains and artificial intelligence. The means speculated to produce intelligence augmentation are numerous, and include bio- and genetic engineering, nootropic drugs, AI assistants, direct brain- computer interfaces, and mind transfer. Despite the numerous speculated means for amplifying human intelligence, non-human artificial intelligence (specifically seed AI) is the most popular option for organizations trying to advance the singularity, a choice addressed by Singularity Institute for Artificial Intelligence (2002). Hanson (1998) is also skeptical of human intelligence augmentation, writing that once one has exhausted the "low-hanging fruit" of easy methods for increasing human intelligence, further improvements will become increasingly difficult to find. It is difficult to directly compare silicon-based hardware with neurons. But Berglas (2008) notes that computer speech recognition is approaching human capabilities, and that this capability seems to require 0.01% of the volume of the brain. This analogy suggests that modern computer hardware is within a few orders of magnitude as powerful as the human brain. It is also noted that the entire human genome is only about 750 megabytes of data, of which only 1.5% codes genes, most of which have nothing to do with intelligence. There is also only about 1% difference in the genes of a human and chimpanzee. This suggests that the "software" in the brain we are born with is relatively small — there is simply no storage space for a huge, arbitrary program. One other factor potentially hastening the singularity is the ongoing expansion of the community working on it, resulting from the increase in scientific research within developing countries. [edit] Economic aspects Dramatic changes in the rate of economic growth have occurred in the past because of some technological advancement. Based on population growth, the economy doubled every 250,000 years from the Paleolithic era until the Neolithic Revolution. This new agricultural economy began to double every 900 years, a remarkable increase. In the current era, beginning with the Industrial Revolution, the world’s economic output doubles every fifteen years, sixty times faster than in the agricultural era. If the rise of superhuman intelligences causes a similar revolution, one would expect the economy to double at l
