Pundit ClaimsAI claims by Gary Marcus and Ed Zitron, with the evidence

“I guarantee you Anthropic, Google and Meta are all working on something doing exactly the same thing, because what they are describing is something that limits every single Large Language Model due to the very nature of how they’re built, something Reuters even acknowledges by adding that “this is something that has eluded AI models to date.””

Put Up Or Shut Up, paragraph 23. The full statement is at the source.

Our reading, the sentence that was checked:

Every LLM is limited by its nature in planning ahead and autonomously doing research, and Anthropic, Google and Meta are all working on the same problem.

From the speaker

  • Anthropic, Google and Meta
  • are all working on something doing exactly the same thing
  • limits every single Large Language Model
  • due to the very nature of how they’re built

Our interpretation

  • The referenced capability is planning ahead to navigate the web autonomously and reliably for research.
  • Exactly the same thing means a comparable research objective, not identical code or model architecture.
  • The claim combines three companies' development activity with a universal, architecture-based explanation of model limitations.
  • I use July 2024 through the post date as the current reporting window. Earlier research is context, not proof that an identical project remained active then.

Counts as supported if: Records establish that all three named companies were developing comparable autonomous research capabilities by the post date, while evaluations and technical analysis establish the claimed shared architectural limitation.

Counts as contradicted if: Reliable records show that a named company was not pursuing that objective, or a contemporary LLM demonstrates the allegedly missing reliable autonomous research capability, or technical evidence refutes the asserted architectural cause.

Retrospective: these criteria were written after the outcome was public.

Current assessment

Was it true for the period described?

Outcome: Unresolved

The record was checked, and the evidence available by the cutoff does not settle it.

Scored on a plain reading. The speaker named no measure for this claim, so it was judged on the reading an informed reader would take, stated below under our interpretation. Both reviews had to find that reading fair.

Rationale

Anthropic reported agentic coding results in June 2024 [e1]. Google-affiliated researchers described web planning and action-taking in July 2023 [e2]. Meta's May 6, 2024 GAIA record describes a benchmark involving reasoning, browsing and tools [e3]. These records do not establish comparable autonomous-research projects active at all three companies during July 1–16, 2024 [e1] [e2] [e3]. A July 1, 2024 paper reports low success rates on tested web tasks and improvements from adding search [e4]. Those findings establish limitations in the tested agents, but do not establish an inherent architectural barrier affecting every LLM [e4]. Both the company-specific development claim and the universal architectural explanation remain unresolved [e1] [e2] [e3] [e4].

Limitations

  • The company records concern different activities and predate the target period [e1] [e2] [e3].
  • The demonstrated web actions do not establish reliable autonomous research [e2].
  • The evaluations do not establish architecture as the necessary cause of every LLM's limitations [e4].

Evidence (4 items)

  • Supports the claim: arXiv; Jing Yu Koh and colleagues,

    still far worse than humans.

    Why it matters here: The contemporary paper supports the limited proposition that web agents had substantial capability gaps. Its improvements from inference-time search do not establish that every model's limitations were inherent in its architecture.

    Why it matters here: Anthropic was developing and evaluating agentic capabilities before the post. Coding performance does not establish a comparable autonomous web-research project or a universal architectural limit.

    Why it matters here: This establishes earlier Google-affiliated work on planning and acting on websites. It also cautions against reading Zitron as claiming that all autonomous web action was impossible, but does not establish reliable deep research in July 2024.

What would settle it

Dated records establishing or ruling out comparable autonomous-research projects at each named company during July 1–16, 2024, plus technical analysis and contemporary evaluations testing the asserted architectural necessity against a defined research task and reliability threshold.
