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

“To be clear, LLMs can absolutely write code, and can absolutely create software, but neither of those mean that the code is good, stable or secure, or that the same can be said of the software they create.”

AI Is Really Weird, paragraph 84. The full statement is at the source.

Our reading, the sentence that was checked:

LLMs can write code and create software, but that doesn't mean the code is good, stable, or secure.

From the speaker

  • LLMs can absolutely write code
  • can absolutely create software
  • neither of those mean that the code is good, stable or secure
  • the same can be said of the software they create

Our interpretation

  • Use 2026 Q1, the latest completed quarter before publication.
  • The plain reading is that code-generation capability does not itself guarantee software quality, stability, or security.
  • The sentence does not say that all generated code is defective or that it is necessarily worse than human-written code.
  • A working generated program with documented material defects is enough to demonstrate the absence of the asserted guarantee; population-wide defect rates are unnecessary.

Counts as supported if: Public artifacts or evaluations show that LLMs produce functioning software while generated outputs can still contain material correctness, stability, or security defects.

Counts as contradicted if: Evidence establishes that generating functioning software itself assures the listed quality properties within the claim's scope.

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

Current assessment

Was it true for the period described?

Outcome: Supported

The dated evidence matches what the claim committed to, under the criteria frozen before grading.

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

A public generated compiler both performed substantial compilation work and exhibited regressions, crashes, and hangs. This supports the modest claim that generating code and software does not guarantee quality or stability. Successful outputs are consistent with the claim, which expressly acknowledges that capability.

Limitations

  • This does not establish how often generated software is defective or compare it with human-written software.
  • The decisive examples concern functionality and stability; they do not separately measure security across coding LLMs.
  • The external bug reports were inspected as records, not independently reproduced.

Evidence (3 items)

  • Supports the claim: Anthropic,

    not all

    Why it matters here: Anthropic's generated compiler demonstrates substantive software-generation capability while retaining functional limitations. That directly fits the distinction in Zitron's sentence.

  • Supports the claim: Anthropic,

    broke existing functionality

    Why it matters here: The developer reports regressions in functioning generated software. Generation capability therefore did not guarantee stability in this example.

  • Supports the claim: bi6c, GitHub issue tracker,

    10 unique bugs

    Why it matters here: External testers identified compiler panics and hangs and supplied locations and reproduction materials. This independently supports the existence of material defects in the generated program.
