| Re: What will the next 150 years be like? These are a few of the predictions Ray Kurzweil has made. He has been making future predictions for decades and almost all of them were accurate so far. 2030s Nanomachines could be directly inserted into the brain and could interact with brain cells to totally control incoming and outgoing signals. As a result, truly full-immersion virtual reality could be generated without the need for any external equipment. Afferent nerve pathways could be blocked, totally canceling out the "real" world and leaving the user with only the desired virtual experience. Brain nanobots could also elicit emotional responses from users. Using brain nanobots, recorded or real-time brain transmissions of a person's daily life known as "experience beamers" will be available for other people to remotely experience. This is very similar to how the characters in Being John Malkovich were able to enter the mind of Malkovich and see the world through his eyes. Recreational uses aside, nanomachines in peoples' brains will allow them to greatly expand their cognitive, memory and sensory capabilities, to directly interface with computers, and to "telepathically" communicate with other, similarly augmented humans via wireless networks. The same nanotechnology should also allow people to alter the neural connections within their brains, changing the underlying basis for the person's intelligence, memories and personality. Human body 2.0 (as Kurzweil calls it) is incrementally accumulated into this decade. It consists of a nanotechnological system of nourishment and circulation, obsolescing many internal organs, and an improved skeleton. 2040s 2045: The Singularity $1000 buys a computer a billion times more intelligent than every human combined. This means that average and even low-end computers are vastly smarter than even highly intelligent, unenhanced humans. The Singularity occurs as artificial intelligences surpass human beings as the smartest and most capable life forms on the Earth. Technological development is taken over by the machines, who can think, act and communicate so quickly that normal humans cannot even comprehend what is going on. The machines enter into a "runaway reaction" of self-improvement cycles, with each new generation of A.I.s appearing faster and faster. From this point onwards, technological advancement is explosive, under the control of the machines, and thus cannot be accurately predicted. The Singularity is an extremely disruptive, world-altering event that forever changes the course of human history. The extermination of humanity by violent machines is unlikely (though not impossible) because sharp distinctions between man and machine will no longer exist thanks to the existence of cybernetically enhanced humans and uploaded humans. Post-2045: "Waking up" the Universe The physical bottom limit to how small computer transistors (or other equivalent, albeit more effective components, such as memristors integrated into Crossbar latches) can be shrunk is reached. From this moment onwards, computers can only be made more powerful if they are made larger in size. Because of this, A.I.s convert more and more of the Earth's matter into engineered, computational substrate capable of supporting more A.I.s. until the whole Earth is one, gigantic computer. At this point, the only possible way to increase the intelligence of the machines any farther is to begin converting all of the matter in the universe into similar massive computers. A.I.s radiate out into space in all directions from the Earth, breaking down whole planets, moons and meteoroids and reassembling them into giant computers. This, in effect, "wakes up" the universe as all the inanimate "dumb" matter (rocks, dust, gases, etc.) is converted into structured matter capable of supporting life (albeit synthetic life). Kurzweil predicts that machines might have the ability to make planet-sized computers by 2099, which underscores how enormously technology will advance after the Singularity. The process of "waking up" the universe could be complete as early as 2199, or might take billions of years depending on whether or not machines could figure out a way to circumvent the speed of light for the purposes of space travel. With the entire universe made into a giant, highly efficient supercomputer, AI and human hybrids (so integrated that, in truth it is a new category of "life") would have both supreme intelligence and physical control over the universe. Kurzweil suggests that this would open up all sorts of new possibilities, including abrogation of the laws of Physics, interdimensional travel, and a possible infinite extension of existence (true immortality). |
