Ben Goertzel (born 1966) is an American AI researcher and entrepreneur best known as an advocate of Artificial General Intelligence (AGI). AGI refers to machines with broad, human-like intelligence – capable of learning or performing any intellectual task a person can. Goertzel has led or founded many companies and research projects (including Webmind, Novamente, OpenCog and SingularityNET) aiming toward this goal. He was chief scientist at Hanson Robotics (working on the humanoid robot Sophia) and later co-founded SingularityNET, a blockchain-based AI platform. Throughout his career Goertzel has emphasized a hybrid approach to intelligence that combines symbolic rule-based methods with neural-network learning. He is also a prominent transhumanist, reflecting his long-term view of AI’s impact on society.
Early Life and Education
Ben Goertzel was born in Rio de Janeiro, Brazil, on December 8, 1966, to American parents. His father, Ted Goertzel, was a sociology professor at Rutgers University. His family moved to the United States when he was a child, and Goertzel grew up in a home rich in science and the humanities. A precocious student, he left high school after tenth grade to enroll at Simon’s Rock College of Bard, an early-college program in Massachusetts. He completed a bachelor’s degree in Quantitative Studies there, and went on to graduate school. In 1989 he earned a Ph.D. in mathematics from Temple University in Philadelphia.
After finishing his doctorate, Goertzel worked in academia in the late 1980s and early 1990s, holding research and teaching positions in mathematics, cognitive science and complex systems at universities in the United States, New Zealand and Australia. This period laid the groundwork for his interdisciplinary approach, as he explored the connections between psychology, dynamical systems and computation. In the mid-1990s, he also became a novelist and publisher, reflecting his broad interests. By 1997 Goertzel decided to leave academia and try building advanced AI in industry.
Major Projects and Ideas
Goertzel’s career has spanned a succession of experimental AI companies and open-source initiatives. In 1997 he founded the company Intelligenesis, later renamed Webmind, based in New York. Webmind aimed to create a “global brain” by developing intelligent software to navigate and learn from the Internet. It built a prototype system with natural-language and pattern-recognition capabilities. However, Webmind was a dot-com era startup that ultimately failed to secure funding. By 2001 the company had shut down, after burning through its investments. (By that time Goertzel had already authored a book, Creating Internet Intelligence (2002), outlining how the Internet could evolve into a distributed cognitive system.)
In response to Webmind’s collapse, Goertzel founded the company Novamente LLC in 2001 as a successor project. Novamente continued his work on AGI, developing the Novamente AI Engine, a software platform intended to model the mind. In a 2007 paper, Goertzel and collaborator Cassio Pennachin described this engine as an “integrative” AI system that combines multiple paradigms: symbolic reasoning, probabilistic inference, evolutionary learning and neural-network methods In other words, Novamente aimed to leverage the strengths of various AI approaches in one architecture. Novamente’s technology was also applied commercially; for example, Goertzel’s group started Biomind LLC around 2002 to use AI for gene-expression analysis in bioinformatics.
In parallel with his commercial ventures, Goertzel helped build the academic and open-source foundation of the AGI community. He co-founded the Artificial General Intelligence (AGI) Society and later chaired its annual conference series, first held in 2006. These conferences collected papers on the theory and practice of general intelligence. He also co-founded the OpenCog Foundation in 2008, launching OpenCog as a public, open-source AGI research framework OpenCog implements many of Goertzel’s ideas: it represents knowledge in a large graph structure called the AtomSpace (nodes and links) and runs multiple cognitive algorithms on it. This architecture exemplifies his idea of “cognitive synergy,” where logic-based inference, pattern recognition and learning processes all operate together on the same data. In OpenCog, for example, each link in the knowledge graph carries a probabilistic truth value and an “attention” weight (akin to a neural network weight) blending symbolic facts with weighted connections.
Goertzel’s publications and ideas have also circulated widely. Early in his career (1993–1997) he published several theoretical books proposing mathematical models of mind. These include The Structure of Intelligence (1993) and Chaotic Logic (1994), which explore how complex mental processes might emerge from interacting components. His 2006 book The Hidden Pattern: A Patternist Philosophy of Mind laid out a comprehensive philosophy for AGI, exploring how mind could be viewed as evolving patterns. In 2014 he co-edited the volume Engineering General Intelligence, a collection of research on AGI architectures. Later he wrote a more public-oriented book, The AGI Revolution: An Inside View of the Rise of Artificial General Intelligence (2016), describing the state of the field and his predictions for the future.
In more recent years, Goertzel has focused on fusing AI with blockchain and decentralized models. In 2017 he co-founded SingularityNET, a decentralized marketplace for AI services The idea is that developers can publish AI algorithms as services on the network, and users can “buy” these services with cryptocurrency. Goertzel’s goal is to democratize access to AI by avoiding central control by big tech companies. SingularityNET’s initial coin offering (ICO) raised tens of millions of dollars within minutes, reflecting investor enthusiasm. More recently, Goertzel has spoken of building an “Artificial Superintelligence Alliance” (launched around 2024) to unite open-source AGI efforts Throughout, he has maintained that these ventures all move toward his vision of crossing a threshold to true AGI.
Approach and Methods
Goertzel defines intelligence very broadly, emphasizing pattern detection and goal-directed behavior. In a 2007 talk he stated that intelligence is “the ability to detect patterns in the world and in the agent itself, measurable in terms of emergent behavior achieving complex goals in complex environments” By emergent behavior, he means sophisticated capabilities that arise from the interaction of simpler processes. Instead of hardwiring a robot with all knowledge, he proposes giving an AI a simple “baby” mind and letting it learn. For instance, he has spoken of training a starter AI agent inside a simulated or virtual environment (like a video game world) where it can explore and develop more advanced skills over time This developmental, bottom-up strategy contrasts with trying to program adult-level intelligence directly.
A hallmark of Goertzel’s method is combining symbolic and connectionist techniques. Symbolic AI refers to representing knowledge with explicit symbols and logical rules (like expert systems), while connectionist AI refers to neural networks that learn statistical patterns from data. These approaches were often seen as rivals, but Goertzel argues that both are needed for AGI. In his envisioned systems (as in OpenCog), knowledge is stored as an interconnected network where each node or relationship has an associated probability and weight. For example, a link might say “Cat → isA → Animal” with some confidence value, and also have an “attention” weight that influences learning. Reasoning in this framework involves both logic-like inference and neural-like learning: one part of the system might apply deductive rules (backward chaining inference), while another part adjusts weights through learning or evolutionary search. Goertzel developed algorithms called Probabilistic Logic Networks (PLN) to perform uncertain reasoning in this context. This integrative architecture is at the heart of his cognitive-synergy idea.
In practical terms, Goertzel’s open-source projects often implement this mix: OpenCog, for instance, includes sub-components for logical rule application, fuzzy inference, pattern mining, evolutionary program synthesis and artificial neural networks, all operating on the same knowledge base. He emphasizes self-organization and learning, hoping that emergent structure will lead to general intelligence rather than brittle, narrow behavior. In short, his method is to cast a wide net of AI methods – from language-processing to reinforcement learning – and let them co-evolve in a common system. By contrast with modern industry AI (which often focuses on deep neural networks for specific tasks), Goertzel’s approach is explicitly multi-paradigm and concerned with high-level cognitive architecture.
Influence and Community Roles
Ben Goertzel has been a prominent figure in the small but vocal AGI community for decades. He helped popularize the term “Artificial General Intelligence” in the 2000s; the name itself was coined by his colleague Shane Legg to title a book of Goertzel’s essays, and the term stuck as a label for human-level AI He founded or led many of the key organizations dedicated to AGI research: for example, he co-founded the AGI Society and chairs its conference, he chairs the OpenCog Foundation which supports open-source AGI software, and he was long-time Vice-Chair of Humanity+, a major transhumanist non-profit He also served as Director of Research at the Machine Intelligence Research Institute (MIRI, formerly the Singularity Institute), which focuses on AI safety and existential risk.
Through these roles and his publications, Goertzel has undoubtedly influenced many researchers interested in general-purpose AI. His conferences and edited volumes have provided a forum for AGI ideas. His vision of a decentralized AI future has reached into the blockchain community, and even some mainstream AI researchers are aware of his work: tech press articles on the future of AI often mention him and his projects (for example, MIT Technology Review and The Verge have profiled him’s work Perhaps most notably, he has always maintained that developing AGI will require careful attention to ethics and safety; in public talks he discusses concepts like “friendly AI” and the social implications of superintelligence. By championing both the technical and philosophical sides of AGI, he has helped keep the conversation alive.
Goertzel’s influence also extends through the platforms he has created. The OpenCog codebase has been used by researchers in several countries, and SingularityNET raised awareness of decentralized approaches to AI. Even if many AI labs concentrate on narrow machine learning today, Goertzel can be credited with keeping alive the idea of a general intelligence. He has often pointed out that in the 2000s, talking about AGI was “lunatic fringe,” but now it’s “coming in from the cold” In this sense his legacy may be that the goal of AGI is now discussed at places like DeepMind and OpenAI, albeit usually under terms like “solve intelligence.”
Critiques and Controversies
A balanced view of Goertzel’s career must note that many experts are skeptical of his vision. The mainstream AI community generally focuses on narrow machine learning and regards AGI talk as speculative or premature. Figures like Facebook’s AI chief Jerome Pesenti have openly criticized the idea: Pesenti went so far as to call AGI a “bugbear” and said he doesn’t even understand what the term means New York University researcher Julian Togelius tweeted that “belief in AGI is like belief in magic,” reflecting a common sentiment Andrew Ng, former head of Google Brain, has advised people to “cut out the AGI nonsense and spend more time on urgent problems” In this environment, Goertzel’s persistent optimism can seem eccentric. He has repeatedly predicted that AGI is only a few years or a decade away – for instance, around 2017 he said machines could match human intelligence in 5–10 years and in 2025 he projected an AGI breakthrough in the next 1–3 years So far, such predictions have not been borne out on any clear timeline.
Goertzel’s commercial and publicity projects have also drawn critique. Some AI experts view the robot Sophia — of which he was a chief scientific advisor — as largely a media creation rather than a true intelligence. The Verge reported that many observers consider Sophia “best categorized as a chatbot with a face,” and that claiming it has near-human AI is misleading Goertzel himself admitted in interviews that Sophia is not AGI, but he defended the hype by saying it attracts attention and talent to AI research Similarly, some skeptics question whether combining AI with cryptocurrency (as in SingularityNET) is a substantive advance or a marketing strategy. Critics argue that tokenizing AI services might not solve any core technical problems and risk distracting from research.
Another critique is that Goertzel’s approach has produced interesting concepts but few widely-acknowledged results. OpenCog exists as an open library, but it has not (yet) demonstrated an AGI system beyond research prototypes. Some say his ideas are too eclectic or philosophical to lead directly to a breakthrough. His heavy use of jargon (terms like “cosmist” or “friendly singularity”) also sometimes alienates mainstream readers. Lastly, as with any visionary, there is debate over how far we should invest in AGI when current AI has important issues (data bias, job impacts, safety) to solve. Detractors suggest that focusing on immediate challenges might be more practical. Nevertheless, Goertzel’s supporters argue that raising questions about AGI now is a valuable precaution.
Legacy and Current Role
Ben Goertzel is still actively working, so the full measure of his legacy remains to be seen. However, he has already carved a unique place in the history of AI. As one of the first to champion AGI as a research goal, his writings and projects have inspired a generation of enthusiasts who believe in human-level AI. He helped turn the idea of “superintelligence” from a fringe conjecture into a topic of public debate and research agendas. Even critics now acknowledge that thinking about AI’s long-term future (as Goertzel has) is important for guiding policy and ethics.
Much of his continuing legacy lies in the community infrastructure he built. The AGI conferences and OpenCog code provide a platform for others to contribute. SingularityNET, whether successful or not, has provoked discussion on how AI could be shared rather than locked up by tech giants. In interviews he often stresses that AGI research should be open, collaborative and benevolent – principles that align with broader movements for open science and ethical AI.
In sum, Goertzel’s work has had an outsized impact on those interested in the question “Can machines truly think?” Even now, terms he promoted (AGI, global brain, singularity) are widely used, if sometimes contentiously. If future breakthroughs do lead to human-level AI, philosophers and historians may look back at his code, essays and initiatives as early steps in that journey. Regardless of when or whether AGI is achieved, his vision of blending brain-like learning with symbolic intelligence and of aligning AI with human values is likely to remain a reference point in debates about the future of technology.
