Raymond "Ray" Kurzweil (/ˈkɜrzwl/ KURZ-wyl; born February 12, 1948) is an American author, computer scientist, inventor, futurist, and is a director of engineering at Google. Aside from futurology, he is involved in fields such as optical character recognition (OCR), text-to-speech synthesis, speech recognition technology, and electronic keyboard instruments. He has written books on health, artificial intelligence (AI), transhumanism, the technological singularity, and futurism. Kurzweil is a public advocate for the futurist and transhumanist movements, as has been displayed in his vast collection of public talks, wherein he has shared his primarily optimistic outlooks on life extension technologies and the future of nanotechnology, robotics, and biotechnology.

Kurzweil was the principal inventor of the first CCD flatbed scanner,[2] the first omni-font optical character recognition,[2] the first print-to-speech reading machine for the blind,[3] the first commercial text-to-speech synthesizer,[4] the Kurzweil K250 music synthesizer capable of simulating the sound of the grand piano and other orchestral instruments, and the first commercially marketed large-vocabulary speech recognition.[5]

Kurzweil received the 1999 National Medal of Technology and Innovation, America's highest honor in technology, from President Clinton in a White House ceremony. He was the recipient of the $500,000 Lemelson-MIT Prize for 2001,[6] the world's largest for innovation. And in 2002 he was inducted into the National Inventors Hall of Fame, established by the U.S. Patent Office. He has received twenty honorary doctorates, and honors from three U.S. presidents. Kurzweil has been described as a "restless genius"[7] by The Wall Street Journal and "the ultimate thinking machine"[8] by Forbes. PBS included Kurzweil as one of 16 "revolutionaries who made America"[9] along with other inventors of the past two centuries. Inc. magazine ranked him #8 among the "most fascinating" entrepreneurs in the United States and called him "Edison's rightful heir".[10]

Kurzweil has authored seven books, five of which have been national bestsellers. The Age of Spiritual Machines has been translated into 9 languages and was the #1 best-selling book on Amazon in science. Kurzweil's book The Singularity Is Near was a New York Times bestseller, and has been the #1 book on Amazon in both science and philosophy. His latest bestseller is How to Create a Mind: The Secret of Human Thought Revealed.[11] Kurzweil speaks widely to audiences public and private and regularly delivers keynote speeches at industry conferences like DEMO, SXSW and TED. His website catalogs his public speaking, publications and media appearances.[12] He maintains the news website KurzweilAI.net, which has over three million readers annually.[5]

Life, inventions, and business career

Early life

Ray Kurzweil grew up in the New York City borough of Queens. He was born to secular Jewish parents who had escaped Austria just before the onset of World War II. He was exposed via Unitarian Universalism to a diversity of religious faiths during his upbringing. His unitarian church had the philosophy of many paths to the truth – the religious education consisted of spending six months on a single religion before moving onto the next. Kurzweil is an agnostic[13] and panpsychist.[14] His father was a musician, a noted conductor, and a music educator. His mother was a visual artist. Kurzweil decided he wanted to be an inventor at the age of five.[15] In his youth, Kurzweil was an avid reader of science fiction literature. At the age of eight, nine, and ten, he read the entire Tom Swift Jr. series. At the age of seven or eight, he built a robotic puppet theater and robotic game. He was involved with computers and built computing devices by the age of twelve. At the age of fourteen, Kurzweil wrote a paper detailing his theory of the neocortex.[16] His parents were involved with the arts, and he is quoted in the documentary Transcendent Man as saying that the household always produced discussions about the future and technology.

Kurzweil attended Martin Van Buren High School. During class, he often held onto his class textbooks to seemingly participate, but instead, focused on his own projects which were hidden behind the book. His uncle, an engineer at Bell Labs, taught young Kurzweil the basics of computer science.[17] In 1963, at age fifteen, he wrote his first computer program.[18] He created a pattern-recognition software program that analyzed the works of classical composers, and then synthesized its own songs in similar styles. In 1965, he was invited to appear on the CBS television program I've Got a Secret, where he performed a piano piece that was composed by a computer he also had built.[19] Later that year, he won first prize in the International Science Fair for the invention;[20] Kurzweil's submission to Westinghouse Talent Search of his first computer program alongside several other projects resulted in him being one of its national winners, which allowed him to be personally congratulated by President Lyndon B. Johnson during a White House ceremony. These activities collectively impressed upon Kurzweil the belief that nearly any problem could be overcome.[21]

Mid-life

While in high school, Kurzweil had corresponded with Marvin Minsky and was invited to visit him at MIT, which he did. Kurzweil also visited Professor Rosenblatt at Cornell.[22]

He obtained a B.S. in computer science and literature in 1970 at MIT. He went to MIT to study with Marvin Minsky. He took all of the computer programming courses (eight or nine) offered at MIT in the first year and a half.

In 1968, during his sophomore year at MIT, Kurzweil started a company that used a computer program to match high school students with colleges. The program, called the Select College Consulting Program, was designed by him and compared thousands of different criteria about each college with questionnaire answers submitted by each student applicant. Around this time, he sold the company to Harcourt, Brace & World for $100,000 (roughly $670,000 in 2013 dollars) plus royalties.[23]

In 1974, Kurzweil founded Kurzweil Computer Products, Inc. and led development of the first omni-font optical character recognition system, a computer program capable of recognizing text written in any normal font. Before that time, scanners had only been able to read text written in a few fonts. He decided that the best application of this technology would be to create a reading machine, which would allow blind people to understand written text by having a computer read it to them aloud. However, this device required the invention of two enabling technologies—the CCD flatbed scanner and the text-to-speech synthesizer. Development of these technologies was completed at other institutions such as Bell Labs, and on January 13, 1976, the finished product was unveiled during a news conference headed by him and the leaders of the National Federation of the Blind. Called the Kurzweil Reading Machine, the device covered an entire tabletop.

Kurzweil's next major business venture began in 1978, when Kurzweil Computer Products began selling a commercial version of the optical character recognition computer program. LexisNexis was one of the first customers, and bought the program to upload paper legal and news documents onto its nascent online databases.

Kurzweil sold his company to Lernout & Hauspie. Following the bankruptcy of the latter, the system became a subsidiary of Xerox formerly known as Scansoft and now as Nuance Communications, and he functioned as a consultant for the former until 1995.

Kurzweil's next business venture was in the realm of electronic music technology. After a 1982 meeting with Stevie Wonder, in which the latter lamented the divide in capabilities and qualities between electronic synthesizers and traditional musical instruments, Kurzweil was inspired to create a new generation of music synthesizers capable of accurately duplicating the sounds of real instruments. Kurzweil Music Systems was founded in the same year, and in 1984, the Kurzweil K250 was unveiled. The machine was capable of imitating a number of instruments, and in tests musicians were unable to discern the difference between the Kurzweil K250 on piano mode from a normal grand piano.[24] The recording and mixing abilities of the machine, coupled with its abilities to imitate different instruments, made it possible for a single user to compose and play an entire orchestral piece.

Kurzweil Music Systems was sold to Korean musical instrument manufacturer Young Chang in 1990. As with Xerox, Kurzweil remained as a consultant for several years. Hyundai acquired Young Chang in 2006 and in January 2007 appointed Raymond Kurzweil as Chief Strategy Officer of Kurzweil Music Systems.[25]

Later life

Concurrent with Kurzweil Music Systems, Kurzweil created the company Kurzweil Applied Intelligence (KAI) to develop computer speech recognition systems for commercial use. The first product, which debuted in 1987, was an early speech recognition program.

Kurzweil started Kurzweil Educational Systems in 1996 to develop new pattern-recognition-based computer technologies to help people with disabilities such as blindness, dyslexia and ADD in school. Products include the Kurzweil 1000 text-to-speech converter software program, which enables a computer to read electronic and scanned text aloud to blind or visually impaired users, and the Kurzweil 3000 program, which is a multifaceted electronic learning system that helps with reading, writing, and study skills.

Raymond Kurzweil at the Singularity Summit at Stanford in 2006

During the 1990s Kurzweil founded the Medical Learning Company.[26] The company's products included an interactive computer education program for doctors and a computer-simulated patient. Around the same time, Kurzweil started KurzweilCyberArt.com—a website featuring computer programs to assist the creative art process. The site used to offer free downloads of a program called AARON—a visual art synthesizer developed by Harold Cohen—and of "Kurzweil's Cybernetic Poet", which automatically creates poetry. During this period he also started KurzweilAI.net, a website devoted towards showcasing news of scientific developments, publicizing the ideas of high-tech thinkers and critics alike, and promoting futurist-related discussion among the general population through the Mind-X forum.

In 1999, Kurzweil created a hedge fund called "FatKat" (Financial Accelerating Transactions from Kurzweil Adaptive Technologies), which began trading in 2006. He has stated that the ultimate aim is to improve the performance of FatKat's A.I. investment software program, enhancing its ability to recognize patterns in "currency fluctuations and stock-ownership trends."[27] He predicted in his 1999 book, The Age of Spiritual Machines, that computers will one day prove superior to the best human financial minds at making profitable investment decisions. In June 2005, Kurzweil introduced the "Kurzweil-National Federation of the Blind Reader" (K-NFB Reader)—a pocket-sized device consisting of a digital camera and computer unit. Like the Kurzweil Reading Machine of almost 30 years before, the K-NFB Reader is designed to aid blind people by reading written text aloud. The newer machine is portable and scans text through digital camera images, while the older machine is large and scans text through flatbed scanning.

In December 2012 Kurzweil was hired by Google in a full-time position to "work on new projects involving machine learning and language processing".[28] Google co-founder Larry Page and Kurzweil agreed on a one-sentence job description: "to bring natural language understanding to Google".[29]

Personal life

Kurzweil married Sonya Rosenwald Fenster in 1975 and has two children.[30] Sonya Kurzweil is a psychologist in private practice and clinical instructor in Psychology at Harvard Medical School; she is interested in the way that digital media can be integrated into the lives of children and teens.[31]

He has a son, Ethan Kurzweil, a venture capitalist,[32] and a daughter, Amy Kurzweil.[33]

Creative approach

Kurzweil said "I realize that most inventions fail not because the R&D department can’t get them to work, but because the timing is wrong - not all of the enabling factors are at play where they are needed. Inventing is a lot like surfing: you have to anticipate and catch the wave at just the right moment."[34][35]

For the past several decades, Kurzweil's most effective and common approach to doing creative work has been conducted during his lucid dreamlike state which immediately precedes his awakening state. He claims to have constructed inventions, solved difficult problems, such as algorithmic, business strategy, organizational, and interpersonal problems, and written speeches in this state.[22]

Books

Kurzweil's first book, The Age of Intelligent Machines, was published in 1990. The nonfiction work discusses the history of computer artificial intelligence (AI) and forecasts future developments. Other experts in the field of AI contribute heavily to the work in the form of essays. The Association of American Publishers' awarded it the status of Most Outstanding Computer Science Book of 1990.[36]

In 1993, Kurzweil published a book on nutrition called The 10% Solution for a Healthy Life. The book's main idea is that high levels of fat intake are the cause of many health disorders common in the U.S., and thus that cutting fat consumption down to 10% of the total calories consumed would be optimal for most people.

In 1999, Kurzweil published The Age of Spiritual Machines, which further elucidates his theories regarding the future of technology, which themselves stem from his analysis of long-term trends in biological and technological evolution. Much emphasis is on the likely course of AI development, along with the future of computer architecture.

Kurzweil's next book, published in 2004, returned to human health and nutrition. Fantastic Voyage: Live Long Enough to Live Forever was co-authored by Terry Grossman, a medical doctor and specialist in alternative medicine.

The Singularity Is Near, published in 2005, was made into a movie starring Pauley Perrette from NCIS.[37] In February 2007, Ptolemaic Productions acquired the rights to The Singularity is Near, The Age of Spiritual Machines and Fantastic Voyage including the rights to film Kurzweil's life and ideas for the documentary film Transcendent Man, which was directed by Barry Ptolemy.

Transcend: Nine Steps to Living Well Forever,[38] a follow-up to Fantastic Voyage, was released on April 28, 2009.

Kurzweil's latest book, How to Create a Mind: The Secret of Human Thought Revealed, was released on Nov. 13, 2012.[39] In it Kurzweil describes his Pattern Recognition Theory of Mind, the theory that the neocortex is a hierarchical system of pattern recognizers, and argues that duplicating this architecture in machines could lead to an artificial superintelligence.[40]

Kurzweil is also writing a novel called Danielle, about his imaginary superheroine daughter who solves problems through intelligence.[41]

Movies

Kurzweil wrote and co-produced a movie directed by Anthony Waller, called The Singularity Is Near: A True Story About the Future, in 2010 based, in part, on his 2005 book The Singularity Is Near. Part fiction, part non-fiction, he interviews 20 big thinkers like Marvin Minsky, plus there is a B-line narrative story that illustrates some of the ideas, where a computer avatar (Ramona) saves the world from self-replicating microscopic robots. In addition to his movie, an independent, feature-length documentary was made about Kurzweil, his life, and his ideas, called Transcendent Man.
Filmmakers Barry Ptolemy and Felicia Ptolemy followed Kurzweil, documenting his global speaking-tour. Premiered in 2009 at the Tribeca Film Festival, Transcendent Man documents Kurzweil's quest to reveal mankind's ultimate destiny and explores many of the ideas found in his New York Times bestselling book, The Singularity Is Near, including his concept exponential growth, radical life expansion, and how we will transcend our biology. The Ptolemys documented Kurzweil's stated goal of bringing back his late father using AI. The film also features critics who argue against Kurzweil's predictions.

In 2010, an independent documentary film called Plug & Pray premiered at the Seattle International Film Festival, in which Kurzweil and one of his major critics, the late Joseph Weizenbaum, argue about the benefits of eternal life.[42]

The feature-length documentary film The Singularity by independent filmmaker Doug Wolens (released at the end of 2012), showcasing Kurzweil, has been acclaimed as "a large-scale achievement in its documentation of futurist and counter-futurist ideas” and “the best documentary on the Singularity to date."[43]

Kurzweil frequently comments on the application of cell-size nanotechnology to the workings of the human brain and how this could be applied to building AI. While being interviewed for a February 2009 issue of Rolling Stone magazine, Kurzweil expressed a desire to construct a genetic copy of his late father, Fredric Kurzweil, from DNA within his grave site. This feat would be achieved by exhumation and extraction of DNA, constructing a clone of Fredric and retrieving memories and recollections—from Ray's mind—of his father.[44] Kurzweil kept all of his father's records, notes, and pictures in order to maintain as much of his father as he could. Ray is known for taking over 200 pills a day, meant to reprogram his biochemistry. This, according to Ray, is only a precursor to the devices at the nano scale that will eventually replace a blood-cell, self updating of specific pathogens to improve the immune system.[44]

Views

The Law of Accelerating Returns

In his 1999 book The Age of Spiritual Machines Kurzweil proposed "The Law of Accelerating Returns", according to which the rate of change in a wide variety of evolutionary systems (including the growth of technologies) tends to increase exponentially.[45] He gave further focus to this issue in a 2001 essay entitled "The Law of Accelerating Returns", which proposed an extension of Moore's law to a wide variety of technologies, and used this to argue in favor of Vernor Vinge's concept of a technological singularity.[46] Kurzweil suggests that this exponential technological growth is counter-intuitive to the way our brains perceive the world—since our brains were biologically inherited from humans living in a world that was linear and local—and, as a consequence, he claims it has encouraged great skepticism in his future projections.

Stance on the future of genetics, nanotechnology, and robotics

Kurzweil is working with the Army Science Board to develop a rapid response system to deal with the possible abuse of biotechnology. He suggests that the same technologies that are empowering us to reprogram biology away from cancer and heart disease could be used by a bioterrorist to reprogram a biological virus to be more deadly, communicable, and stealthy. However, he suggests that we have the scientific tools to successfully defend against these attacks, similar to the way we defend against computer software viruses. He has testified before Congress on the subject of nanotechnology, advocating that nanotechnology has the potential to solve serious global problems such as poverty, disease, and climate change. "Nanotech Could Give Global Warming a Big Chill".[47]

In media appearances, Kurzweil has stressed the extreme potential dangers of nanotechnology[19] but argues that in practice, progress cannot be stopped because that would require a totalitarian system, and any attempt to do so would drive dangerous technologies underground and deprive responsible scientists of the tools needed for defense. He suggests that the proper place of regulation is to ensure that technological progress proceeds safely and quickly, but does not deprive the world of profound benefits. He stated, "To avoid dangers such as unrestrained nanobot replication, we need relinquishment at the right level and to place our highest priority on the continuing advance of defensive technologies, staying ahead of destructive technologies. An overall strategy should include a streamlined regulatory process, a global program of monitoring for unknown or evolving biological pathogens, temporary moratoriums, raising public awareness, international cooperation, software reconnaissance, and fostering values of liberty, tolerance, and respect for knowledge and diversity."[48]

Health and aging

Kurzweil admits that he cared little for his health until age 35, when he was found to suffer from a glucose intolerance, an early form of type II diabetes (a major risk factor for heart disease). Kurzweil then found a doctor (Terry Grossman, M.D.) who shares his non-conventional beliefs to develop an extreme regimen involving hundreds of pills, chemical intravenous treatments, red wine and various other methods to attempt to live longer. Kurzweil was ingesting "250 supplements, eight to 10 glasses of alkaline water and 10 cups of green tea" every day and drinking several glasses of red wine a week in an effort to "reprogram" his biochemistry.[49] Lately, he has cut down the number of supplement pills to 150.[50]

Kurzweil joined the Alcor Life Extension Foundation, a cryonics company. In the event of his declared death, Kurzweil will be perfused with cryoprotectants, vitrified in liquid nitrogen, and stored at an Alcor facility in the hope that future medical technology will be able to repair his tissues and revive him.[51]

He has authored three books on the subjects of nutrition, health and immortality: The 10% Solution for a Healthy Life, Fantastic Voyage: Live Long Enough to Live Forever and Transcend: Nine Steps to Living Well Forever.[52] In all, he recommends that other people emulate his health practices to the best of their abilities. Kurzweil and his current "anti-aging" doctor, Terry Grossman, MD., now have two websites promoting their first[53] and second book.[54]

He claims to know that in the future, everyone will live forever.[55] In a 2013 interview, Kurzweil said that in 15 years, medical technology could add more than a year to one's remaining life expectancy for each year that passes, and we could then "outrun our own deaths". He has been an extreme advocate of SENS Research Foundation for the successful defeating of aging, and has encouraged acts of donation to hasten their rejuvenation research.[29][56]

Kurzweil's view of the human neocortex

According to Kurzweil, technologists will be creating synthetic neocortexes based on the operating principles of the human neocortex with the primary purpose of extending our own neocortexes. He claims to believe that the neocortex of an adult human consists of approximately 300 million pattern recognizers. He draws on the commonly accepted belief that the primary anatomical difference between humans and other primates that allowed for superior intellectual abilities was the evolution of a larger neocortex. He claims that the six-layered neocortex deals with increasing abstraction from one layer to the next. He says that at the low levels, the neocortex may seem cold and mechanical because it can only make simple decisions, but at the higher levels of the hierarchy, the neocortex is likely to be dealing with concepts like being funny, being sexy, expressing a loving sentiment, creating a poem or understanding a poem, etc. He claims to believe that these higher levels of the human neocortex were the enabling factors to permit the human development of language, technology, art, and science. He stated, "If the quantitative improvement from primates to humans with the big forehead was the enabling factor to allow for language, technology, art, and science, what kind of qualitative leap can we make with another quantitative increase? Why not go from 300 million pattern recognizers to a billion?”[57]

Encouraging futurism and transhumanism

Kurzweil's standing as a futurist and transhumanist has led to his involvement in several singularity-themed organizations. In December 2004, Kurzweil joined the advisory board of the Singularity Institute for Artificial Intelligence.[58] In October 2005, Kurzweil joined the scientific advisory board of the Lifeboat Foundation.[59] On May 13, 2006, Kurzweil was the first speaker at the Singularity Summit at Stanford.[60] In May 2013, Kurzweil was the keynote speaker at the 2013 proceeding of the Research, Innovation, Start-up and Employment (RISE) international conference in Seoul, Korea Republic.[61]

In February 2009, Kurzweil, in collaboration with Google and the NASA Ames Research Center, announced the creation of the Singularity University training center for corporate executives and government officials. The University's self-described mission is to "assemble, educate and inspire a cadre of leaders who strive to understand and facilitate the development of exponentially advancing technologies and apply, focus and guide these tools to address humanity's grand challenges".[62] Using Vernor Vinge's Singularity concept as a foundation, the university offered its first nine-week graduate program to 40 students in June, 2009.

Predictions

Past predictions

Kurzweil's first book, The Age of Intelligent Machines, presented his ideas about the future. It was written from 1986 to 1989 and published in 1990. Building on Ithiel de Sola Pool's "Technologies of Freedom" (1983), Kurzweil claims to have forecast the demise of the Soviet Union due to new technologies such as cellular phones and fax machines disempowering authoritarian governments by removing state control over the flow of information.[63] In the book Kurzweil also extrapolated preexisting trends in the improvement of computer chess software performance to predict that computers would beat the best human players "by the year 2000".[64] In May 1997 chess World Champion Garry Kasparov was defeated by IBM's Deep Blue computer in a well-publicized chess tournament.[65]

Perhaps most significantly, Kurzweil foresaw the explosive growth in worldwide Internet use that began in the 1990s. At the time of the publication of The Age of Intelligent Machines, there were only 2.6 million Internet users in the world,[66] and the medium was unreliable, difficult to use, and deficient in content. He also stated that the Internet would explode not only in the number of users but in content as well, eventually granting users access "to international networks of libraries, data bases, and information services". Additionally, Kurzweil claims to have correctly foreseen that the preferred mode of Internet access would inevitably be through wireless systems, and he was also correct to estimate that the latter would become practical for widespread use in the early 21st century.

Kurzweil's predictions for 2009 were mostly inaccurate, claims Forbes magazine. For example, Kurzweil predicted, "The majority of text is created using continuous speech recognition." This is not the case.[67]

Future predictions

In 1999, Kurzweil published a second book titled The Age of Spiritual Machines, which goes into more depth explaining his futurist ideas. The third and final part of the book is devoted to predictions over the coming century, from 2009 through 2099. In The Singularity Is Near he makes fewer concrete short-term predictions, but includes many longer-term visions.

He states that with radical life extension will come radical life enhancement. He says he is confident that within 10 years we will have the option to spend some of our time in 3D virtual environments that appear just as real as real reality, but these will not yet be made possible via direct interaction with our nervous system. "If you look at video games and how we went from pong to the virtual reality we have available today, it is highly likely that immortality in essence will be possible." He claims to know that 20 to 25 years from now, we will have millions of blood-cell sized devices, known as nanobots, inside our bodies fighting against diseases, improving our memory, and cognitive abilities. Kurzweil claims to know that a machine will pass the Turing test by 2029, and that around 2045, "the pace of change will be so astonishingly quick that we won't be able to keep up, unless we enhance our own intelligence by merging with the intelligent machines we are creating". Shortly after, Kurzweil claims to know that humans will be a hybrid of biological and non-biological intelligence that becomes increasingly dominated by its non-biological component. He stresses that "AI is not an intelligent invasion from Mars. These are brain extenders that we have created to expand our own mental reach. They are part of our civilization. They are part of who we are. So over the next few decades our human-machine civilization will become increasingly dominated by its non-biological component. In Transcendent Man Kurzweil states "We humans are going to start linking with each other and become a metaconnection we will all be connected and all be omni-present, plugged into this global network that is connected to billions of people, and filled with data." [68] Kurzweil states in a press conference that we are the only species that goes beyond our limitations- "we didn't stay in the caves, we didn't stay on the planet, and we're not going to stay with the limitations of our biology". In his singularity based documentary he is quoted saying "I think people are fooling themselves when they say they have accepted death".

In 2008, Kurzweil said in an expert panel in the National Academy of Engineering that solar power will scale up to produce all the energy needs of Earth's people in 20 years. According to Kurzweil, we only need to capture 1 part in 10,000 of the energy from the Sun that hits Earth's surface to meet all of humanity's energy needs.[69]

Reception

Praise

Kurzweil was referred to as "the ultimate thinking machine" by Forbes[8] and as a "restless genius"[7] by The Wall Street Journal.

Criticism

Kurzweil's ideas have generated criticism within the scientific community and in the media.
Although the idea of a technological singularity is a popular concept in science fiction, some authors such as Neal Stephenson[91] and Bruce Sterling have voiced skepticism about its real-world plausibility. Sterling expressed his views on the singularity scenario in a talk at the Long Now Foundation entitled The Singularity: Your Future as a Black Hole.[92][93] Other prominent AI thinkers and computer scientists such as Daniel Dennett,[94] Rodney Brooks,[95] David Gelernter[96] and Paul Allen[97] also criticized Kurzweil's projections.

Daniel Lyons, writing in Newsweek, criticized Kurzweil for some of his predictions that turned out to be wrong, such as the economy continuing to boom from the 1998 dot-com through 2009, a US company having a market capitalization of more than $1 trillion, a supercomputer achieving 20 petaflops, speech recognition being in widespread use and cars that would drive themselves using sensors installed in highways; all by 2009.[98] To the charge that a 20 petaflop supercomputer was not produced in the time he predicted, Kurzweil responded that he considers Google a giant supercomputer, and that it is indeed capable of 20 petaflops.[98]

In the cover article of the December 2010 issue of IEEE Spectrum, John Rennie criticizes Kurzweil for several predictions that failed to become manifest by the originally predicted date. "Therein lie the frustrations of Kurzweil's brand of tech punditry. On close examination, his clearest and most successful predictions often lack originality or profundity. And most of his predictions come with so many loopholes that they border on the unfalsifiable."[99]

Bill Joy, cofounder of Sun Microsystems, agrees with Kurzweil's timeline of future progress, but thinks that technologies such as AI, nanotechnology and advanced biotechnology will create a dystopian world.[100] Mitch Kapor, the founder of Lotus Development Corporation, has called the notion of a technological singularity "intelligent design for the IQ 140 people...This proposition that we're heading to this point at which everything is going to be just unimaginably different—it's fundamentally, in my view, driven by a religious impulse. And all of the frantic arm-waving can't obscure that fact for me."[101]

Some critics have argued more strongly against Kurzweil and his ideas. Cognitive scientist Douglas Hofstadter has said of Kurzweil's and Hans Moravec's books: "It's an intimate mixture of rubbish and good ideas, and it's very hard to disentangle the two, because these are smart people; they're not stupid."[102] Biologist P. Z. Myers has criticized Kurzweil's predictions as being based on "New Age spiritualism" rather than science and says that Kurzweil does not understand basic biology.[103][104] VR pioneer Jaron Lanier has even described Kurzweil's ideas as "cybernetic totalism" and has outlined his views on the culture surrounding Kurzweil's predictions in an essay for Edge.org entitled One Half of a Manifesto.[43][105]

In a critical review of Kurzweil's book How to Create a Mind: The Secret of Human Thought Revealed, philosopher Colin McGinn refers to "the hype so blatantly brandished in its title" and asks: "He is clearly a man of many parts—but is ultimate theoretician of the mind one of them?" McGinn calls Kurzweil's claim that pattern recognition is the key to mental phenomena "obviously false" and concludes that the book is "interesting in places, fairly readable, moderately informative, but wildly overstated".[106]

John Gray, the British philosopher, argues that contemporary science is what magic was for ancient civilizations. It gives a sense of hope for those who are willing to do almost anything in order to achieve eternal life. He quotes Kurzweil's Singularity as another example of a trend which has almost always been present in the history of mankind.[107]

Nassim Nicholas Taleb, Lebanese American essayist, scholar and statistician, criticized his approach of taking multiple pills to achieve longevity in his book Antifragile.

Hans Christian Ørsted (/ˈɜrstɛd/;[3] Danish: [ˈhanˀs ˈkʰʁæsd̥jan ˈɶɐ̯sd̥ɛð]; often rendered Oersted in English; 14 August 1777 – 9 March 1851) was a Danish physicist and chemist who discovered that electric currents create magnetic fields, an important aspect of electromagnetism. He shaped post-Kantian philosophy and advances in science throughout the late 19th century.[4]

In 1824, Ørsted founded Selskabet for Naturlærens Udbredelse (SNU), a society to disseminate knowledge of the natural sciences. He was also the founder of predecessor organizations which eventually became the Danish Meteorological Institute and the Danish Patent and Trademark Office. Ørsted was the first modern thinker to explicitly describe and name the thought experiment.

A leader of the so-called Danish Golden Age, Ørsted was a close friend of Hans Christian Andersen and the brother of politician and jurist Anders Sandøe Ørsted, who eventually served as Danish prime minister (1853–54).

The oersted (Oe), the cgs unit of magnetic H-field strength, is named after him.

Early life and studies


The young H.C. Ørsted

Ørsted was born in Rudkøbing. As a young boy Ørsted developed his interest in science while working for his father, who owned a pharmacy.[5] He and his brother Anders received most of their early education through self-study at home, going to Copenhagen in 1793 to take entrance exams for the University of Copenhagen, where both brothers excelled academically. By 1796 Ørsted had been awarded honors for his papers in both aesthetics and physics. He earned his doctorate in 1799 for a dissertation based on the works of Kant entitled "The Architectonics of Natural Metaphysics".

In 1801 Ørsted received a travel scholarship and public grant which enabled him to spend three years travelling across Europe. In Germany he met Johann Wilhelm Ritter, a physicist who believed there was a connection between electricity and magnetism. This made sense to Ørsted since he believed in Kantian ideas about the unity of nature and that deep relationships existed between natural phenomena.[5]

Their conversations drew Ørsted into the study of physics. He became a professor at the University of Copenhagen in 1806 and continued his research with electric currents and acoustics. Under his guidance the University developed a comprehensive physics and chemistry program and established new laboratories.

In 1800, Alessandro Volta discovered a galvanic battery inspiring Ørsted to think about the nature of electricity and to conduct his first electrical experiments. Between 1800 to 1803, he visited to Germany, France and Holland for lectures. He again visited Germany and France in 1812 after publishing a manual called Videnskaben om Naturens Almindelige Love and Første Indledning til den Almindelige Naturlære (1811). In Berlin he wrote his famous essay on the identity of chemical and electrical forces in which he first stated the connection existing between magnetism and electricity. Then, in Paris he translated that essay in Latin with Marcel de Serres.

The Royal Society of London gave him the Copley Medal and the French Academy awarded him with 3,000 gold francs. Ørsted was just 43 when he made this great discovery. He established the Royal Polytechnic Institute in 1829 of which he was the first director.

Electromagnetism

On 21 April 1820, during a lecture, Ørsted noticed a compass needle deflected from magnetic north when an electric current from a battery was switched on and off, confirming a direct relationship between electricity and magnetism.[6] His initial interpretation was that magnetic effects radiate from all sides of a wire carrying an electric current, as do light and heat. Three months later he began more intensive investigations and soon thereafter published his findings, showing that an electric current produces a circular magnetic field as it flows through a wire. This discovery was not due to mere chance, since Ørsted had been looking for a relation between electricity and magnetism for several years. The special symmetry of the phenomenon was possibly one of the difficulties that retarded the discovery.[7]

It is sometimes claimed that Italian Gian Domenico Romagnosi was the first person who found a relationship between electricity and magnetism, about two decades before Ørsted's 1820 discovery of electromagnetism. Romagnosi's experiments showed that an electric current from a voltaic pile could deflect a magnetic needle.[8] His researches were published in two Italian newspapers and were largely overlooked by the scientific community.[9]

Ørsted's findings stirred much research into electrodynamics throughout the scientific community, influencing French physicist André-Marie Ampère's developments of a single mathematical formula to represent the magnetic forces between current-carrying conductors. Ørsted's work also represented a major step toward a unified concept of energy.

In 1822, he was elected a foreign member of the Royal Swedish Academy of Sciences.

Later years

In 1825, Ørsted made a significant contribution to chemistry by producing aluminium for the first time. While an aluminium-iron alloy had previously been developed by British scientist and inventor Humphry Davy, Ørsted was the first to isolate the element via a reduction of aluminium chloride.
In 1829, Ørsted founded Den Polytekniske Læreanstalt ('College of Advanced Technology') which was later renamed the Technical University of Denmark (DTU).[10]

Ørsted died at Copenhagen in 1851, aged 73, and was buried in the Assistens Cemetery in the same city.

Legacy

The centimetre-gram-second system (CGS) unit of magnetic induction (oersted) is named for his contributions to the field of electromagnetism.

The 100 danske kroner note issued from 1950 to 1970 carried an engraving of Ørsted. The buildings that are home to the Department of Chemistry and the Institute for Mathematical Sciences at the University of Copenhagen are named The H.C. Ørsted Institute, after him. The first Danish satellite, launched 1999, was named after Ørsted. Two medals are awarded in Ørsted's name: the Oersted Medal for notable contributions in the teaching of physics in America, awarded by American Association of Physics Teachers, along with the H. C. Ørsted Medal for Danish scientists, awarded by the Danish Selskabet for Naturlærens Udbredelse (Society for the Dissemination of Natural Science), which Ørsted founded. The H.C. Ørsted Lectureship is awarded to two prominent researchers annually, and has been bestowed upon the following scientists:

Writings

Ørsted was a published writer and poet. His poetry series Luftskibet ("The Airship") was inspired by the balloon flights of fellow physicist and stage magician Étienne-Gaspard Robert.[14] Shortly before his death, he submitted a collection of articles for publication under the title "The Soul in Nature".
The book presents Ørsted's life philosophy and views on a wide variety of issues.[15]
