Ray Kurzweil

Kurzweil was born on February 12, 1948, in the New York City borough of Queens and grew up in an academic family; his father was a musician and conductor and his mother a visual artist, and both encouraged his creativity. At five he began building his own model boats, cars and rockets, at 12 he built a simple computing device, and he learned to program with the help of an uncle who was an engineer at Bell Labs.⁠[1][2][3][3][3][3]

Kurzweil began his first pattern-recognition project at 15. In high school he taught a computer to recognize patterns in compositions by Mozart and Chopin and create melodies in their styles; the project won first prize at the International Science Fair and a place in the Westinghouse Science Talent Search, which took him to the White House to meet President Lyndon Johnson, and in 1965 he appeared on the television show I’ve Got a Secret, hosted by Steve Allen. In high school he also began corresponding with MIT artificial intelligence pioneer Marvin Minsky, and he graduated from Martin Van Buren High School in New York in 1965.⁠[3][4][4][4][3][2]

Kurzweil chose the Massachusetts Institute of Technology partly because of his relationship with Minsky, majoring in computer science and creative writing (or, by another account, computer science and literature). As a sophomore he started the Select College Consulting Program, which used a computer program to match high school students with colleges; to handle a database of 2 million college facts he had to pay $1,000 an hour to use the only computer in New England with enough memory. The business was later sold to the publisher Harcourt, Brace & World for $100,000 plus royalties. He received his bachelor’s degree from MIT in 1970.⁠[3][1][4][4][4][3]

In 1974 Kurzweil founded Kurzweil Computer Products to pursue pattern-recognition technologies such as optical character recognition. At the time OCR could only read fonts designed for machines, such as Courier and OCR-A; his team developed the first “omni-font” OCR capable of reading any typeface and the first flatbed scanner to use a charge-coupled device (CCD). By the National Inventors Hall of Fame’s count, he has founded nine companies since 1973.⁠[4][4][1][1][1]

In 1976 Kurzweil introduced the Kurzweil Reading Machine, which combined omni-font OCR, the CCD flatbed scanner and the first full text-to-speech synthesizer to turn print into computer speech, enabling blind and visually impaired people to read printed material; it was regarded as the most significant advance for the blind since the introduction of Braille in 1829. Using only 64K of memory, the machine scanned text line by line, recognized each character, determined pronunciation from pre-programmed phonological rules and spoke the words through a synthesizer, and it has been called the first commercial product to use artificial intelligence technology successfully. The musician Stevie Wonder was among its first users, and the two became friends.⁠[3][4][1][1][3][3][4]

In the early 1980s Stevie Wonder suggested to Kurzweil the idea of bridging the gap between acoustic and electronic instruments. In 1982 the two, with software engineer Bruce Cichowlas, co-founded Kurzweil Music Systems, with Wonder as musical adviser, aiming to capture and recreate the true sounds of acoustic instruments such as the grand piano, violin, guitar and drums. The team’s K250 keyboard synthesizer is regarded as the first electronic instrument to successfully reproduce the sounds of acoustic instruments; accounts date its introduction to 1983 or 1984. In 1990 Kurzweil sold the company to the Korean instrument maker Young Chang.⁠[3][5][3][3][3][4][3]

In 1987 Kurzweil Applied Intelligence, a company he founded, released the first commercial speech recognition system and developed a specialized system that let physicians create medical reports on their computers by voice. Later versions allowed all typing, editing and formatting of a text file to be done by voice alone and gradually adapted to a user’s speech habits, making fewer mistakes over time.⁠[4][4][3][3]

In 1990 Kurzweil published his first book, The Age of Intelligent Machines, accompanied by an award-winning documentary film. Its predictions about the course of computing in the 1990s and early 2000s, including the emergence of the World Wide Web, a computer defeating the world chess champion by 1998 and the use of intelligent weapons in warfare, have been recognized as fairly accurate. The same year he was named Design News’ Engineer of the Year.⁠[4][4][3][3]

In 1994 Kurzweil received the Dickson Prize from Carnegie Mellon University. In 1996 he started his fourth company, Kurzweil Educational Systems, to create and market print-to-speech reading technology for visually impaired students; the company, now Kurzweil Education, is owned by Cambium Learning.⁠[4][4][5]

In 1999 Kurzweil published The Age of Spiritual Machines: When Computers Exceed Human Intelligence, predicting that the lines between humans and computers would blur in the near future. He later said that in it he predicted AI would draw enormous interest within 30 years, when people thought it would take a century or more. The same year he received the National Medal of Technology from President Bill Clinton.⁠[4][6][3][1]

In 2001 Kurzweil won the $500,000 Lemelson-MIT Prize. The same year he published the essay “The Law of Accelerating Returns,” arguing that technological progress accelerates exponentially, so that the 21st century would bring not 100 years of progress but something more like 20,000 years (at the then-current rate), with machine intelligence surpassing human intelligence within a few decades.⁠[3][7][8][8]

In 2002 Kurzweil was inducted into the National Inventors Hall of Fame for his work on optical character recognition. In the early 2000s he also worked with the National Federation of the Blind to develop the K-NFB Reader mobile app (later renamed the OneStep Reader), which could photograph printed text anywhere and read it aloud.⁠[1][5][5][5]

On September 22, 2005, Kurzweil published The Singularity Is Near, which predicted that computers would reach human-level intelligence by 2029 and that humans would merge with computers and become superhuman around 2045, a moment he called “the Singularity”; the book also responded specifically to criticisms of The Age of Spiritual Machines. It became a New York Times bestseller.⁠[9][6][7][9]

In 2008 Kurzweil and XPRIZE founder Peter DiamandisPeter DiamandisPeter Diamandis is a co-founder and partner of Link-XPV, a co-founder and partner of BOLD Capital Partners, and the founder and executive chairman of XPRIZE.

Inspired by The Singularity Is Near, Diamandis pitched the idea of a new university to educate tomorrow’s leaders at a dinner; the school was launched with support from NASA, Google and others and began a 10-week Graduate Studies Program.⁠[10][11][10][10][10]

On November 29, 2010, IEEE Spectrum published John Rennie’s critique “Ray Kurzweil’s Slippery Futurism,” which, citing Kurzweil’s 2005 TED claim that “by 2010 computers will disappear,” argued that his most successful predictions often lack originality and that most come with so many loopholes they border on the unfalsifiable, yet still earn him impressive speaker fees; the article also acknowledged that his genius as an inventor is “beyond dispute.”⁠[12][12][12][12][12]

On December 23 Kurzweil replied in a letter to the magazine, saying the article was filled with misquotes and misunderstandings and that Rennie had discussed only a handful of the more than 100 predictions for 2009 he made in the late 1990s, often getting them wrong; he noted that at least 98 percent of computers in and around the home are embedded in everyday products such as appliances and cars, and said it was the first time anyone had called one of his predictions both wrong and obvious.⁠[13][13][13][13]

On October 12, 2011, MicrosoftMicrosoftMicrosoft is a technology company founded by Bill Gates and Paul Allen in 1975 and headquartered in Redmond, Washington, with businesses spanning Windows, Microsoft 365, Azure, enterprise software, artificial intelligence, gaming and devices.Open the full entry co-founder Paul AllenPaul AllenPaul Allen (1953–2018) was an American entrepreneur, investor and philanthropist who co-founded Microsoft with Bill Gates in 1975. After leaving Microsoft’s management in 1983 he founded the investment and project-management firm Vulcan, owned the NFL’s Seattle Seahawks and the NBA’s Portland Trail Blazers, funded private spaceflight projects including SpaceShipOne and Stratolaunch, and created institutions such as the Allen Institute for Brain Science and the Allen Institute for Artificial Intelligence, giving more than $2.65 billion to philanthropy during his life.Open the full entry and his colleague Mark Greaves published “The Singularity Isn’t Near” in MIT Technology Review, arguing that the singularity, even if it eventually occurs, is not near; that the Law of Accelerating Returns is an assertion about predicting the future from the past rather than a physical law; and that the 2045 prediction seemed “quite far-fetched,” requiring unforeseeable, fundamentally unpredictable breakthroughs.⁠[8][8][8][8]

On October 20 Kurzweil responded in the same publication, saying Allen had paraphrased his book’s title but appeared not to have read The Singularity Is Near, citing only his 2001 essay and not addressing the book’s arguments; drawing an analogy with the laws of thermodynamics, he argued that while individual technology projects are unpredictable, the overall trajectory of price-performance and capacity follows remarkably predictable paths.⁠[7][7][7][7]

On November 13, 2012, Kurzweil published How to Create a Mind, which, like The Singularity Is Near, became a New York Times bestseller.⁠[14][14]

On December 14, 2012, Kurzweil announced he was joining Google as a director of engineering, starting on December 17, to work on new projects in machine learning and language processing. He said he was thrilled to team up with Google on some of the hardest problems in computer science “so we can turn the next decade’s ‘unrealistic’ visions into reality.” As of October 2026 he is a principal researcher and AI visionary at Google, leading a team studying how computers can process, understand and use human language.⁠[15][15][15][11][2]

In 2019, in a talk at the COSM conference, investor Peter ThielPeter ThielPeter Thiel is an American entrepreneur and investor, a co-founder of PayPal and Palantir Technologies, and the first outside investor in Facebook. He is a partner at the venture capital firm Founders Fund and founded the Thiel Fellowship, which funds young people to leave college and build new things; his public skepticism of higher education, his support for Trump in 2016, and his funding of litigation against Gawker Media have drawn controversy.Open the full entry criticized the consensus in Silicon Valley and academia that science and technology are progressing extremely fast, citing Kurzweil’s The Singularity Is Near as the utopian version of that accelerationism, in which “all you need to do is sit back, eat some popcorn and watch the movie of the future unfold”; he described the other version as Hollywood-style dystopia, and argued that progress is in fact not as fast as advertised.⁠[16][17][17][17][17][17][17]

In March 2023 the Future of Life Institute published an open letter calling on all AI labs to pause the training of systems more powerful than GPT-4 for at least six months. In April Kurzweil explained why he did not sign: he considered the “more powerful than GPT-4” criterion too vague to be practical and saw a serious coordination problem, since those agreeing to a pause could fall far behind corporations or nations that did not; AI offers tremendous benefits in fields such as medicine, education and renewable energy, and the signers’ safety concerns could be addressed in a more tailored way. He noted that he had taken part in the 2017 Asilomar AI Principles conference and knew that safety is critical.⁠[18][18][18][18][18][18]

On June 25, 2024, Kurzweil published The Singularity Is Nearer, the sequel to The Singularity Is Near, reassessing his 1999 prediction that AI would reach human-level intelligence by 2029 and discussing nanobots, radical life extension beyond the current limit of 120, connecting brains to the cloud, AI’s effect on employment and the potential perils of biotechnology, nanotechnology and artificial intelligence. It became a New York Times bestseller.⁠[11][19][11][11][11][11]

When the book came out he said his 2029 and 2045 dates had not changed, and that by 2029 AI would reach not only human-level intelligence but also artificial general intelligence; he named the main driver as the exponential growth of computing price-performance, which he said doubles every 15 months. He envisions the Singularity arriving when human brains merge with the cloud through molecule-sized nanobots entering the brain noninvasively via the capillaries, expanding intelligence a millionfold by 2045; he also predicted that universal basic income would begin in the 2030s, and said his first plan is to stay alive and reach “longevity escape velocity.”⁠[6][6][6][6][6][6][6][6]

Besides the non-fiction works above, Kurzweil co-wrote the health and longevity books Fantastic Voyage: Live Long Enough to Live Forever and Transcend: Nine Steps to Living Well Forever with physician Terry Grossman. His first novel, Danielle: Chronicles of a Superheroine, an adventure about a young heroine accompanied by two non-fiction companion guides, reached No. 7 on the Publishers Weekly bestseller list and won the Moonbeam Children’s Book Award and the Pinnacle Book Achievement Award.⁠[20][20][2][2][21][21][21]

Kurzweil has received a Grammy Award for outstanding achievement in music technology, 11 honorary doctorates and awards from three U.S. presidents.⁠[11][3]
