BC: EPOCH SIX .. .. .. .. .. .. .. .. . . .. .. .. .. .. ... .. .. .. After mastering the methods of technology and biology, Kurzweil predicts that human/machine civilization will expand its frontiers into the universe, gradually (or perhaps explosively) consuming the contents of the cosmos until the universe reaches a 'saturated' state where all inanimate matter has been converted to substrates for computation and intelligence, and a truly universal super-intelligence takes form. Next, Kurzweil briefly lays out a number of postulates and consequences in the first chapter as they relate to the Singularity. As stated, the Law of Accelerating Returns implies exponential- and non-linear growth in technological capabilities and human knowledge. Information technologies are experiencing superexponential growth since human economic investment in them increases as they become more powerful. Human brain-scanning techniques are reliant upon computers and advanced machines, which are all subject to the Law of Accelerating Returns. Therefore, our ability to understand the way the human brain works is improving tremendously every year. Based on the current trends, brain scans should give us a sound understanding of how the human brain works by the mid-2020s. Using that information, scientists should be able to create simulated human brains inside of computers, leading to the first Artificial Intelligence (a thinking computer capable of passing the Turing Test) by 2029. The computer hardware of that era should also be powerful enough to meet the cognitive needs of a simulated human mind. Artificial Intelligence would inevitably prove superior to human intelligence since the former would combine the fast speeds, memory capacity and recall, and instant downloading/learning abilities of computers with the creativity and pattern-recognition abilities of the human mind, effectively constituting a being with the strengths of both and the weaknesses of neither. Artificial Intelligences would also have the ability to edit their own software at will to instantly improve themselves, which is an ability humans naturally lack and can only approximate through laborious genetic engineering techniques. Biology presents inherent and insurmountable limitations that originate at the molecular level. These limitations handicap both potential mental abilities and physical abilities. This reality will inevitably lead to the creation of synthetic replacement parts that are far more durable and capable than natural human organs, limbs and cells. Some humans will choose to incorporate these engineered prostheses into their bodies, becoming cybernetically enhanced. Nanotechnology will play a major role in human brain augmentation with the advent of brain nanomachines designed specifically for interacting with human neurons. Brain cybernetics of this type would allow human users to vastly expand their cognitive abilities, to experience full-immersion virtual reality, and to directly interface with computers and other mentally augmented humans. Being naturally more powerful, the cybernetic portion of augmented human minds will come to predominate. A very broad range of advanced nanomachines will also be created, allowing the humans and machines of the future to alter their world with incredible power. Aside from the aforementioned brain augmentation role, nanotechnology could be used for a variety of tasks including a total repair of the Earth's environment and the near instantaneous manipulation of physical objects via foglets so as to blur the distinction between "real" and "virtual" reality. Kurzweil foresees the computers of the future using three-dimensional computer chips composed of nanotubes. This architecture will allow them to operate at terahertz speeds. Computer advances like this will eventually make A.I.'s so powerful that they will completely take over the cutting edge of all scientific research and development, and will generate new advancements (including improvements to their own programming) so quickly that normal humans will not be able to follow what is going on. By this point, the Singularity will definitely have been reached. In the far future, A.I.'s and cybernetic humans will live almost exclusively in full-immersion virtual reality worlds, which will themselves be contained in advanced computers. Computers will grow ever more advanced, but at some point, the bottom limit to transistor size as defined by the laws of Physics will be reached, and performance improvements will only be possible through the creation of new computers or the expansion of existing ones. More and more inanimate matter on the Earth will be restructured to form useful computer substrate, but it will eventually prove insufficient, and the future machine race will radiate out from the Earth in all directions, "saturating" first the solar system, then the Milky Way galaxy, and eventually the entire cosmos with "intelligence" by converting unstructured, inanimate "dumb" matter (e.g., Moon rocks, dead gas giant planets, meteoroids) into structured "smart" matter that lives in the sense that it supports thinking, feeling A.I.'s. Entire celestial bodies of countless number across the universe will be totally converted into computer substrate. The length of time it will take to finish the task of "waking up" the universe depends heavily on whether the speed of light can be surpassed or circumvented—the maximum rate of travel of course limiting the speed at which the advanced Earth civilization can spread across space to new locations.
