#103 – Ben Goertzel: Artificial General Intelligence

In plain words

This interview is about Artificial General Intelligence (AGI) — machines that can think like humans. Ben Goertzel thinks big companies like Google control AI and data like "psychopaths," so he prefers decentralized AI networks like SingularityNet. He highlights three things: OpenCog (his AGI system being rewritten because it's too slow, can't work well with neural nets, and can't run on 10,000 machines); Sophia robot (criticized as fake, but he says it's more transparent than Facebook's AI); and GPT-3 (he calls it an "idiot" that understands nothing).

New Arguments and Analysis of Perspectives

Based on the continuation of the dialogue, the following extracts and supplements new arguments, data, and perspectives, focusing on Ben Goertzel's unique insights into the technical path, social impact, and philosophical dimensions of AGI. All analysis is new content and does not repeat the preceding sections.


1. Historical Evolution and Mainstreaming of the AGI Community

Ben details the shift of AGI from "fringe enthusiasts" to "mainstream marketing term," providing specific data:

  • First AGI Workshop (2006): Only about 60 attendees, held in a Bethesda Marriott conference room, with participants mostly "intense-eyed outsiders."
  • Current AGI Conference: Hundreds of attendees annually, becoming the primary gathering for those "not obsessed with deep neural networks but still pursuing AGI."
  • Mainstreaming Milestones: From Putin publicly stating "Russia needs to be the leader in AGI" to Intel's CTO declaring at the 2008 Singularity Summit that "the singularity will occur in 2045, and it will run on Intel chips inside."

New Evidence: Ben argues that the "summers and winters" of AGI are overly exaggerated in the US; in reality, global AI research (Germany, Japan, Russia) has been steadily growing, unaffected by fluctuations in US military funding. For example, Germany had autonomous vehicles in the 1980s, and Russia has a deep foundation in program specialization.


2. Motivation for the OpenCog 2.0 / True AGI Redesign

Ben publicly disclosed for the first time the three major technical bottlenecks driving the redesign of OpenCog, which had not been detailed previously:

Bottleneck Specific Issue Expected Resolution
Type-Checking Speed Checking of higher-order probabilistic dependent types in the current system is extremely slow, making it impossible to support types as first-class citizens Implement faster type inference, supporting variable types and operations between complex types
Deep Neural Network Interoperability Integration with computation graphs from frameworks such as Torch is cumbersome and lacks real-time access capability Design native, efficient serial/parallel interfaces between hypergraphs and neural network computation graphs
Distributed Scalability The current architecture was not designed for the scale of 10,000 machines, and cross-RAM distribution is inefficient Refactor the underlying layer to support large-scale distributed hypergraph storage and processing

New Insight: Ben believes the mathematical paradigm of AGI remains unchanged, but the infrastructure must be upgraded from its 2001–2008 design, otherwise it cannot support modern computational demands. He particularly emphasizes that "graph processors" will have a revolutionary impact on architectures like OpenCog, similar to the impact of GPUs on deep learning.


3. Neural Networks as "Oracle" Rather Than Internal Representation

Ben clearly distinguishes between two ways of utilizing neural networks, and provides specific experimental cases:

  • Grammar Induction Experiment: Uses a Transformer model (e.g., GPT-2) as a "sentence probability oracle" to guide a symbolic grammar learning algorithm. Method: Generate sentences using candidate grammar rules, have the Transformer judge their probabilities, and thus filter rules. Result: More effective than directly extracting the Transformer's internal representation.
  • Rejection of GPT-3's Understanding: Ben states bluntly that "GPT-3 is a complete idiot; it doesn't understand anything." He believes that scale does not lead to understanding, just as "a faster car won't get you to Mars."

New Argument: Cites the InfoGAN example, noting that while InfoGAN can automatically learn semantic variables (e.g., nose length), attempts to extend it into a Bayesian network (e.g., Google's Edward framework) have all failed. Ben speculates that backpropagation may not be able to handle such semantic structures, and that evolutionary algorithms (e.g., CMAES) might be more effective.


4. Decentralized AI vs. Centralized Enterprises

Ben provides new comparative data from a philosophical and political economy perspective:

Dimension Centralized (Google/Amazon/Pharma) Decentralized (SingularityNet/Rejuve)
Data Control Taking 23andMe as an example, its genomic data is exclusively licensed to GlaxoSmithKline, with users unable to share Users maintain autonomous control through secure data wallets, with analysis proceeds returned to network members
AI Talent Flow The majority of AI PhDs are absorbed by 6-12 large corporations Open-source and community-driven projects attract dispersed independent researchers
Ethical Tendency As self-organizing entities, corporations exhibit "psychopathic" traits (even if individuals are well-intentioned) The protocol itself is built on mathematical trust, with no central manipulator
Regulatory Adaptability Vulnerable to government regulation and compliance pressures The protocol layer exists prior to regulation, forming a "fait accompli" that forces regulatory adaptation

New Perspective: Ben argues that the current control of AI and medical data by "psychopathic corporate intelligence" poses a greater threat to humanity than malicious AGI. Citing the precedent of Napster/BitTorrent, he points out that the emergence of decentralized tools can alter the regulatory trajectory.


5. Ethical Defense and Transparency Claims of Sophia Robot

Ben responded to criticism from Jan LeCun and others, presenting new arguments:

  • Transparency: Ben himself has detailed in H+ Magazine the three software systems inside Sophia (timeline editor, hybrid chatbot, OpenCog), and pointed out that Facebook's AI operations are far less transparent than Sophia's.
  • User Perception: Even when users are fully informed that Sophia is remotely operated, they still insist that "it is Phil's soul speaking" (Austin experiment). Ben argues that the human projection of anthropomorphic emotions cannot be eliminated, so the key lies in the use case rather than technical details.
  • Ethical Contrast: Ben retorts: "If Jan LeCun allows Facebook to use machine learning to drive people toward consumerism and political extremism, why not allow machine learning to create a cute, dramatic robot that lets some fools fall into dramatic illusion?"

New Data: Comparative experiment of Sophia's chatbot versus Facebook's Transformer model: Sophia's sentence structure is more repetitive but maintains a long conversational arc; Facebook's model produces more fluent sentences but tends to digress. Neither possesses genuine understanding.


6. Meaning of Life and Values of Superintelligence

Ben proposes "joy, growth, choice" as a triadic value set and offers new arguments:

  • Attitude toward death: Ben argues that "death gives life meaning" is as absurd as "torture gives poetry meaning." He suggests that people should have a "pain adjustment knob" rather than being forced into a pain-free state.
  • Relationship between superintelligence and happiness: Ben refutes the view that "intelligence is a burden," arguing that superintelligence will unlock "new forms of joy" because, with root-level access to one's own brain, it becomes possible to design new subjective experiences.
  • Multiple versions of the self: Ben envisions retaining both a human version (with adjustable pain, immortal) and a superhuman version (merged with AGI), with possible communication between the two. He cites the idea that "one subjective second for a superintelligence could be a million subjective years" to illustrate the difference in time scales.

New evidence: Ben uses his own experience of composing music as an example — when playing the piano, he first plays by feel, then later reflects on and declaratively analyzes his improvisational actions, which resembles the interaction between a neural oracle and symbolic reasoning.


7. Modern Interpretations of Nietzsche and Dostoevsky

Ben offers a new literary-philosophical analysis:

  • Nietzsche’s “Übermensch”: Ben argues that Nietzsche lacked technological imagination, but his analysis of “self-conscious self-construction, the illusion of free will, and the origin of good and evil” closely aligns with the concept of “obtaining the right to modify conscious self” in AGI.
  • Dostoevsky’s “Polyphony”: Ben cites Bakhtin’s theory of the “polyphonic novel,” contending that the interweaving of multiple characters’ subjective perspectives in The Brothers Karamazov reflects how humans collectively construct reality through social interaction—a metaphor for the coordination of multiple cognitive modules in an AGI system.

New Perspective: Ben suggests that if Nietzsche were transported to modern times, he might become addicted to TikTok and fail to produce great works—implying the threat of distraction to new ideas.


8. Specific Cases of COVID-19 Data Sharing and AI Application

Ben provides new data:

  • Personalized medicine: Using OpenCog's BioAtomSpace combined with gene expression data (25,000 genes) and clinical indicators, via graph-to-vector embedding fed into a neural network, for antiviral combination prediction. The key challenge is transfer learning with small samples; Ben argues that probabilistic reasoning algorithms are more suitable for such problems than deep neural networks.
  • Data silo problem: Ben criticizes that COVID clinical trial data is siloed by hospitals, citing the hydroxychloroquine incident (Surgisphere scandal) as a negative example. He proposes establishing a decentralized healthcare data platform similar to Rejuve.io, where users contribute data and share analysis revenue.

Comparison data:

Data Type Suitable Algorithm Limitation
Gene expression matrix (25K dimensions) XGBoost / CatBoost / Deep neural networks Unfriendly to logic engines
Small-sample multi-condition combinatorial clinical data OpenCog probabilistic reasoning Low efficiency in processing high-dimensional floating-point vectors

Summary

Ben Goertzel provides a wealth of new arguments in the sequel, covering technical restructuring (three major bottlenecks of OpenCog 2.0), methodology (neural networks as oracle), social philosophy (decentralization against corporate psychopathy), ethical justification (the legitimacy of Sophia's use), and the meaning of life (joy, growth, choice). These perspectives supplement his unique viewpoint as a core figure in the AGI field, with particular emphasis on the urgency of "building decentralized infrastructure before new technologies become entrenched."
