Many of the most recognized writers on the singularity, such as Vernor Vinge and Ray Kurzweil, define the concept in terms of the technological creation of superintelligence, and argue that it is difficult or impossible for present-day humans to predict what a post-singularity would be like, due to the difficulty of imagining the intentions and capabilities of superintelligent entities .A good way to understand the singularity is to imagine explaining the internet to somebody living in the year 1200. Your frames of reference would be so different that it would be almost impossible to convey how the internet works, let alone what it means to our society. You are on the other side of what seems like a singularity to our person from the Middle Ages. But from the perspective of a future singularity, we are the medieval ones. Advances in science and technology mean that singularities might happen over periods much shorter than 800 years. And nobody knows for sure what the hell they'll bring. Artificial intelligence is the technology that most people believe will usher in the singularity. Authors like Vinge and singulatarian Ray Kurzweil think AI will usher in the singularity for a twofold reason. First, creating a new form of intelligent life will completely change our understanding of ourselves as humans. Second, AI will allow us to develop new technologies so much faster than we could before that our civilization will transform rapidly. A corollary to AI is the development of robots who can work alongside - and beyond - humans. Another singularity technology is the self-replicating molecular machine, also called autonomous nanobots, "gray goo," and a host of other things. Basically the idea is that if we can build machines that manipulate matter at the atomic level, we can control our world in the most granular way imaginable. And if these machines can work on their own? Who knows what will happen. For a dark vision of this singularity, see Greg Bear's novel Blood Music or Bill Joy's essay "The Future Doesn't Need Us"; for a more optimistic vision, Rudy Rucker's Postsingular. And finally, a lot of singulatarian thought is devoted to the idea that synthetic biology, genetic engineering, and other life sciences will eventually give us control of the human genome. Two world-altering events would come out of that. One, we could engineer new forms of life and change the course of human evolution in one generation. Two, it's likely that control over our genomes will allow us to tinker with the mechanisms that make us age, thus dramatically increasing our lifespans. Many futurists, from Kurzweil and Steward Brand, to scientists like Aubrey De Gray, have suggested that extreme human longevity (in the hundreds of years) is a crucial part of the singularity. Kurzweil predicts, based on mathematical calculations of exponential technological development, that the Singularity will come to pass by 2045. Most arguments against the possibility of the Singularity involve doubts that computers can ever become intelligent in the human sense. The human brain and cognitive processes may simply be more complex than a computer could be. Martin Ford in The Lights in the Tunnel: Automation, Accelerating Technology and the Economy of the Future postulates a "technology paradox" in that before the singularity could occur most routine jobs in the economy would be automated, since this would require a level of technology inferior to that of the singularity. This would cause massive unemployment and plummeting consumer demand, which in turn would destroy the incentive to invest in the technologies that would be required to bring about the Singularity. Job displacement is increasingly no longer limited to work traditionally considered to be "routine."
Biotechnology is the use of living systems and organisms to develop or make useful products, or "any technological application that uses biological systems, living...
