2. Redefining Artificial General Intelligence (AGI)

(13:15 – 37:45)

Why AGI Definitions Matter

• Practical Impact: NLW argues AGI definitions are "useless" for daily enterprise AI use, but become critical as progress toward AGI shapes market and investment decisions. (13:25)

Current & Historical Definitions

• Andrej Karpathy: Sets a high bar – AGI can do any economically valuable task at human or better performance, not just knowledge work. (14:55)
  • Quote: "AGI was a system...that could do any economically valuable task at human performance or better." (15:05)
• OpenAI: Evolving definitions—from "AI systems that are generally smarter than humans" (2023), to the "five levels of AI" framework, ranging from chatbots up to organizational-level performance.
• Other Entities:
  • Gartner: AGI as "intelligence of a machine that can accomplish any intellectual task a human can perform."
  • Google: AGI as the hypothetical ability to "understand or learn any intellectual task a human can."
  • Amazon: Software able to "perform tasks not necessarily trained or developed for."
• ARC AGI Prize: Focuses on generalization and skill acquisition, not just task performance. "AGI is a system that can efficiently acquire new skills outside of its training data." (17:20)

The Impact of Definitions

• AGI definitions, once just "nebulous," now influence "how markets should treat AI stocks." (15:50)
• Vague definitions have triggered contract disputes, e.g., Microsoft's deal with OpenAI.

3. The New Quantifiable AGI Framework

(20:40 – 37:45)

• Center for AI Safety’s Paper: "Definition of AGI" (20:40)

  • Proposes a measurable framework, benchmarking a model against the cognitive abilities of a well-educated adult.
  • Grounded in Psychological Theory: Cattell-Horn-Carroll model of cognition.
  • 10 Cognitive Categories: Reading/writing, math, reasoning, working memory, memory (storage and retrieval), visual, auditory, speech, knowledge.

• Scoring Results

  • GPT-4: 27%
  • GPT-5: 58%
    • Major gains in reading/writing, math.
    • New competence in reasoning, memory retrieval, visual, and auditory.
    • Still major deficiencies, especially in memory.

• Analysis of Current Shortfalls

  • Quote (Dan Hendricks, Center for AI Safety): "People who are bullish about AGI timelines rightly point to rapid advancements like math. The skeptics are correct to point out...AIs have many basic cognitive flaws...There are many barriers to AGI, but they each seem tractable." (26:30)
  • Quote (Lewis Gleason, content creator): "For the first time, we have a framework that turns AGI from a buzzword into a measurable spectrum." (28:05)
  • Quote (Rohan Paul, on memory): "[Today's systems] fake memory by stuffing huge context windows and fake precise recall by leaning on retrieval from external tools, which hides real gaps in storing new facts...Both GPT-4 and GPT-5 fail to form lasting memories across sessions and still mix in wrong facts when retrieving, which limits dependable learning and personalization over days or weeks." (33:00)
  • Memory as Bottleneck: No AI yet matches humans in storing/retrieving persistent information over time; even state-of-the-art models "forget" between sessions.

• Utility and Limitations

  • Framework is functional, not economic—high cognitive scoring does not guarantee business value.
  • Some companies, like OpenAI and Microsoft, tie AGI definitions to financial performance (e.g., $100B in profits) for contractual clarity.

• Economic vs. Cognitive AGI

  • Quote (Elon Musk): "AGI is...capable of doing anything a human with a computer can do, but not smarter than all humans and computers combined. ... probably three to five years away." (Elon on X, paraphrased at 36:05)
  • Even without AGI, current models are already "having and will have a profound impact on the economy exactly as they are right now." (37:05)

Notable Quotes & Memorable Moments

• “All of a sudden progress toward AGI is going to be considered a meaningful factor when it comes to how markets should treat AI stocks.” – NLW (13:45)
• "Each category was equally weighted and given a score out of 10...GPT-4 scored 27% while GPT-5 achieved 58%." – NLW, summarizing the new paper (24:40)
• "For the first time, we have a framework that turns AGI from a buzzword into a measurable spectrum.” – Lewis Gleason (28:05)
• "The biggest hole by a mile is around memory." – NLW (31:10)
• "You hear when people critique...models don't have memory and they can't learn in the way that humans do." – NLW (32:55)
• Elon Musk: “AGI is...capable of doing anything a human with a computer can do, but not smarter than all humans and computers combined...probably three to five years away.” (36:05)
• “An incredibly powerful model, whether it's AGI or not, could have a profound impact on the economy.” – NLW (37:10)

Tone and Closing Thoughts

Whittemore adopts an analytical, occasionally skeptical tone, repeatedly noting that "AGI" is more a matter for market sentiment and philosophical debate than daily enterprise impact. But with the introduction of a quantitative framework, the conversation is poised to shift from nebulous speculation to something that "turns AGI from a buzzword into a measurable spectrum." He cautions, however, that business impact and market value may not map cleanly onto cognitive test scores, and memory remains the critical obstacle to true AGI as defined in this new research.

"Ultimately I think this is a extremely useful contribution to the field. I hope that more people dig in and if nothing else, it creates a useful heuristic for the future when inevitably we rage and scream and kick with every new model release about how some big wall has been hit." – NLW (37:28)

Summary Takeaway

This episode brings clarity to a long-murky debate, spotlighting a new, rigorous approach to measuring AGI. While GPT-5 may be 58% 'there' by cognitive benchmarks, massive gaps in persistent memory and "continual learning" remain. For now, AI’s march toward AGI is no longer a matter of pure guesswork; the field finally has a scorecard—even if the economic implications are still up for debate.
