Ray Kurzweil

• 1. Introduction

  ›

  Ray Kurzweil was born on the 12th of February 1948 in Queens, New York City, to parents who had fled Austria just before World War II. By the time he was twelve years old, he had already taught himself to work with computers at a moment when only a dozen such machines existed in all of New York City. That detail alone stops you cold. Most children in 1960 had never seen a computer. Kurzweil was already building them.

  His father was a concert pianist and conductor. His mother was a visual artist. The household, Kurzweil has said, always discussed the future and technology. By his early teens he had read the entire Tom Swift Jr. series, built a robotic puppet theater, and written statistical programs for a predecessor of Head Start. At fifteen, he wrote his first computer program.

  In 1965, at seventeen, he appeared on a CBS television program called I've Got a Secret, where he performed a piano piece composed by a computer he had built himself. President Lyndon B. Johnson personally congratulated him at a White House ceremony after he won first prize at the International Science Fair for the same invention.

  What follows is the story of how a boy from Queens turned that early astonishment into a career that touched blind readers, electronic music, artificial intelligence, and some of the most debated predictions about the human future ever put into print.

  In 1974, Kurzweil founded Kurzweil Computer Products and set out to solve a problem that had quietly limited millions of people: the inability of computers to read text in arbitrary typefaces. Scanners at the time could handle only a handful of fonts. Kurzweil's team built the first omni-font optical character recognition system, capable of reading text in any normal font.

  The logical next step, as Kurzweil saw it, was to turn that recognition into spoken words for people who could not see the page at all. The device required two enabling technologies that did not yet exist: a CCD flatbed scanner and a text-to-speech synthesizer. Development of both was completed at outside institutions, including Bell Labs. On the 13th of January 1976, the finished product was unveiled at a news conference with leaders of the National Federation of the Blind.

  The Kurzweil Reading Machine was large enough to cover an entire tabletop. Stevie Wonder heard about it on The Today Show and later became the user of the first production unit, beginning what would become a long personal and professional association between the two men.

  When a commercial version of the optical character recognition software went on sale in 1978, LexisNexis was among the first customers, buying it to upload paper legal and news documents into nascent online databases. Kurzweil eventually sold the company to Xerox, where it evolved through several names and mergers before becoming part of Nuance Communications in 2005.

  For inventing the Kurzweil Reading Machine, he received the 1978 Grace Murray Hopper Award from the Association for Computing Machinery, along with a $35,000 prize. The National Medal of Technology, the United States' highest honor in technology, followed in 1999, presented by President Bill Clinton at a White House ceremony specifically in recognition of Kurzweil's work helping people with disabilities.

• 3. The Sound of Machines

  After a 1982 meeting with Stevie Wonder, in which Wonder described the gap between what electronic synthesizers could do and what traditional instruments could do, Kurzweil decided to close that gap. Kurzweil Music Systems was founded that same year. In 1984, the Kurzweil K250 was unveiled.

  The K250 could imitate a range of instruments. Kurzweil's press materials claimed that musicians could not tell its piano mode apart from a real grand piano, though reviewers who tested that claim directly raised doubts. What was not in dispute was the machine's recording, mixing, and multi-instrument capability, which made it possible for a single musician to compose and perform an entire orchestral piece.

  South Korean manufacturer Young Chang bought Kurzweil Music Systems in 1990, though Kurzweil stayed on as a consultant. Hyundai later acquired Young Chang in 2006, and in 2007 appointed Kurzweil as Chief Strategy Officer of Kurzweil Music Systems.

  The K250's cultural reach extended into an unlikely corner. On the 12th of December 2000, the Canadian alternative rock band Our Lady Peace released an album called Spiritual Machines on Columbia Records. The project evolved into a conceptual interpretation of Kurzweil's 1999 book The Age of Spiritual Machines. The band had emailed Kurzweil to ask permission to use the book's title. His enthusiasm led them to invite him to record spoken excerpts from the book for inclusion as short interspersed tracks. The Kurzweil K250 keyboard was also used on the recording.

  In 2015, Kurzweil received a Technical Grammy Award specifically for the invention of the K250.

• 4. The Accelerating Returns Thesis

  ›

  Kurzweil's first book, The Age of Intelligent Machines, was written between 1986 and 1989 and published in 1990. The Association of American Publishers named it the Most Outstanding Computer Science Book of that year. In it, Kurzweil laid out predictions that would later be tested against reality: that computers would beat the best human chess players by the year 2000 (IBM's Deep Blue defeated World Champion Garry Kasparov in May 1997), and that the Internet would explode in both users and content, accessed wirelessly in the early 21st century.

  The 1999 book The Age of Spiritual Machines introduced what he called "The Law of Accelerating Returns": the idea that the rate of change in evolutionary systems, including technology, tends to increase exponentially. A 2001 essay extended this into an argument for a technological singularity drawing on John von Neumann's earlier concept.

  In October 2010, Kurzweil published a detailed self-assessment of his predictions. Of 147 predictions, he claimed 115 were entirely correct, 12 essentially correct, 17 partially correct, and three wrong. Critics pushed back. Newsweek identified several 2009 predictions that had not come true, including that the economy would boom and that continuous speech recognition would create the majority of text. Forbes concluded that Kurzweil's 2009 predictions were mostly inaccurate, finding seven incorrect, four partially correct, and one correct.

  The 2005 book The Singularity Is Near was eventually adapted into a film starring Pauley Perrette. Ptolemaic Productions acquired rights to three of his books in 2007, including for the documentary Transcendent Man, directed by Barry Ptolemy. His most recent book, The Singularity Is Nearer: When We Merge with AI, was published in 2024.

• 5. Health as Engineering Problem

  ›

  Kurzweil has said he paid little attention to his own health until age 35, when a diagnosis of glucose intolerance, an early form of type II diabetes, reframed the situation as an engineering problem to be solved rather than a condition to be managed.

  He found a doctor named Terry Grossman and together they developed what Kurzweil described as an unconventional regimen involving hundreds of pills, chemical intravenous treatments, red wine, and various other methods aimed at life extension. By 2007, he was consuming 250 supplements daily, eight to ten glasses of alkaline water, green tea, and several glasses of red wine each week in an effort to reprogram his biochemistry. By 2008 he had reduced the daily pill count to 150. By 2015 he had brought it down to 100.

  Grossman co-authored the 2004 book Fantastic Voyage: Live Long Enough to Live Forever with Kurzweil. A follow-up, Transcend: Nine Steps to Living Well Forever, was released in 2009. The 2012 book How to Create a Mind outlined his Pattern Recognition Theory of Mind, arguing that the neocortex is a hierarchical system of pattern recognizers and that emulating that architecture in machines could yield artificial superintelligence.

• 6. Critics and Supporters

  ›

  Bill Gates called Kurzweil "the best at predicting the future of artificial intelligence". Forbes described him in 1998 as "the ultimate thinking machine". The Wall Street Journal called him "a restless genius" in 1989. PBS placed him among 16 "revolutionaries who made America".

  The critics are equally prominent. Mitch Kapor, founder of Lotus Development Corporation, called the notion of a technological singularity "intelligent design for the IQ 140 people" and said it was fundamentally driven by a religious impulse. Cognitive scientist Douglas Hofstadter described Kurzweil's and Hans Moravec's books as "an intimate mixture of rubbish and good ideas" that were very hard to disentangle. VR pioneer Jaron Lanier coined the phrase "cybernetic totalism" to describe the culture surrounding Kurzweil's predictions, elaborating in an essay for the Edge Foundation called "One Half of a Manifesto".

  Bill Joy, co-founder of Sun Microsystems, agreed with Kurzweil's timeline but believed the technologies would create a dystopian rather than utopian world. Physicist Theodore Modis argued that Kurzweil's singularity thesis lacked scientific rigor. Science fiction authors Neal Stephenson and Bruce Sterling both voiced skepticism about its plausibility; Sterling delivered a 2004 talk at the Long Now Foundation titled The Singularity: Your Future as a Black Hole.

  In December 2012, Google co-founder Larry Page personally hired Kurzweil to work on machine learning and language processing. Page and Kurzweil agreed on a one-sentence job description: to bring natural language understanding to Google. In 2009, Kurzweil joined with Google and the NASA Ames Research Center to announce the creation of Singularity University, which offered its first nine-week graduate program to 40 students that same year.
