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

“Anthropic has not created recursive self-improvement, nor has it done much more than create a very large language model that gets higher benchmarks in tests built for large language models, wrapped in a veneer of mysticism and panic-hype built to scare organizations in paying them to use it.”

AI's Brokenomics, paragraph 14. The full statement is at the source.

Our reading, the sentence that was checked:

Anthropic has not created recursive self-improvement, nor has it done much more than create a very large language model that scores higher on benchmarks built for large language models, wrapped in mysticism and panic-hype meant to scare organizations into paying to use it.

From the speaker

  • Anthropic has not created recursive self-improvement
  • nor has it done much more than create a very large language model
  • gets higher benchmarks
  • built to scare organizations in paying them to use it

Our interpretation

  • Recursive self-improvement means a system autonomously developing a more capable successor, rather than assisting human researchers.
  • The ordinary technical reading of the second clause is that Mythos offered little demonstrated practical advance beyond benchmark scores.
  • The target period covers the April-to-June Mythos development and release sequence described in the context, ending on the post date.
  • The allegation about marketing intent is a separate component. Useful capabilities would not, by themselves, disprove that allegation.

Counts as supported if: Evidence that Anthropic had not achieved autonomous successor development supports the first component. Independent evaluations showing little practical advance outside benchmarks would support the second. Establishing the alleged marketing intent would require direct evidence of that purpose.

Counts as contradicted if: A demonstrated autonomous successor-development cycle would contradict the first component. Substantial verified results on practical tasks outside benchmark tests would contradict the second under the stated reading.

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

Current assessment

Was it true for the period described?

Outcome: Mixed

Part of the claim holds and part does not, and the record says which part is which.

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 itself said it had not achieved recursive self-improvement. That part holds on the public record. The broader dismissal of practical progress is challenged by Mozilla's report of 271 vulnerabilities fixed after its Mythos evaluation. Those are results in deployed software, not merely benchmark scores. The marketing-intent allegation remains unproven. The mixed assessment depends on reading the second clause as a claim about practical capabilities.

Limitations

  • The recursive self-improvement evidence is a company disclosure from June 4, shortly before the post.
  • Mozilla collaborated with Anthropic, although Mozilla maintained the affected software and reported the fixes.
  • The assessment does not resolve the speaker's characterization of marketing motives.

Evidence (2 items)

  • Supports the claim: Anthropic,

    We are not there yet

    Why it matters here: Anthropic explicitly acknowledges that it has not reached the autonomous successor-development capability it defines as recursive self-improvement. This supports that component of Zitron's statement.

  • Goes against the claim: Mozilla,

    Why it matters here: Mozilla identifies the evaluation as its application of Mythos Preview to Firefox. Vulnerabilities fixed in a shipped browser constitute practical results beyond benchmark scores.

What would settle it

Direct evidence of marketing intent and a clearer definition of what the speaker meant by doing much more than improving benchmark performance would resolve the remaining components.
