The legends of Prester John, popular in Europe from the 12th through the 17th centuries, told of a Christian patriarch and king said to rule over a Christian nation lost amidst the Muslims and pagans in the Orient. Written accounts of this kingdom are variegated collections of medieval popular fantasy. Reportedly a descendant of one of the Three Magi, Prester John was said to be a generous ruler and a virtuous man, presiding over a realm full of riches and strange creatures, in which the Patriarch of the Saint Thomas Christians resided. His kingdom contained such marvels as the Gates of Alexander and the Fountain of Youth, and even bordered the Earthly Paradise. Among his treasures was a mirror through which every province could be seen, the fabled original from which derived the “speculum literature” of the late Middle Ages and Renaissance, in which the prince’s realms were surveyed and his duties laid out. Despite the non-existence of Prester John, the medieval belief in the legend affected several hundred years of European and world history, directly and indirectly, by encouraging Europe’s explorers, missionaries, scholars and treasure hunters.

Could the net become self-aware?

In engineering terms, it is easy to see qualitative similarities between the human brain and the internet’s complex network of nodes, as they both hold, process, recall and transmit information. “The internet behaves a fair bit like a mind,” says Ben Goertzel, chair of the Artificial General Intelligence Research Institute, an organisation inevitably based in cyberspace. “It might already have a degree of consciousness”.

Not that it will necessarily have the same kind of consciousness as humans: it is unlikely to be wondering who it is, for instance. To Francis Heylighen, who studies consciousness and artificial intelligence at the Free University of Brussels (VUB) in Belgium, consciousness is merely a system of mechanisms for making information processing more efficient by adding a level of control over which of the brain’s processes get the most resources. “Adding consciousness is more a matter of fine-tuning and increasing control… than a jump to a wholly different level,” Heylighen says.

How might this manifest itself? Heylighen speculates that it might turn the internet into a self-aware network that constantly strives to become better at what it does, reorganising itself and filling gaps in its own knowledge and abilities.  ~newscientist.com

The idea that we live in a hologram probably sounds absurd, but it is a natural extension of our best understanding of black holes, and something with a pretty firm theoretical footing. It has also been surprisingly helpful for physicists wrestling with theories of how the universe works at its most fundamental level.

The holograms you find on credit cards and banknotes are etched on two-dimensional plastic films. When light bounces off them, it recreates the appearance of a 3D image. In the 1990s physicists Leonard Susskind and Nobel prizewinner Gerard ‘t Hooft suggested that the same principle might apply to the universe as a whole. Our everyday experience might itself be a holographic projection of physical processes that take place on a distant, 2D surface.  ~newscientist.com

What does this mean, really?
