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

“We know how to build machines that do math (augmentation); we don’t know how to build machines that can read tax codes (replacement).”

Three baffling claims about AI and machine learning in four days, statistical errors in top journals, and claims from Yann LeCun that you should not believe., paragraph 23. The full statement is at the source.

Our reading, the sentence that was checked:

We do not currently know how to build machines that can read and understand tax codes well enough to replace accountants.

From the speaker

  • We know how to build machines that do math
  • we don’t know how to build machines that can read tax codes
  • replacement

Our interpretation

  • In context, read tax codes means interpret and apply tax law reliably enough to perform an accountant's tax-judgment work, including deductibility decisions.
  • It does not mean displaying text, recognizing characters, finding passages or executing rules already translated by people.
  • The reference to replacement does not require automation of unrelated accounting duties.
  • I use the current-year reporting window through publication for this ongoing capability claim, rather than a later model's capabilities.

Counts as supported if: Evidence covering the contemporary state of the field establishes that available systems lacked reliable autonomous interpretation and application of tax law at the stated replacement standard.

Counts as contradicted if: A system available by the post date demonstrates reliable autonomous tax-law interpretation and application across representative accountant judgment tasks, without case-by-case human translation of the governing rules.

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

The [statutory-reasoning research](https://arxiv.org/abs/2105.07903) documents serious earlier machine-reading limitations. The [original benchmark](https://arxiv.org/abs/2005.05257) also shows why human-authored rule execution must be distinguished from reading tax law autonomously. These sources are consistent with Marcus's contextual claim, but they are earlier, restricted evaluations. They do not establish the field-wide October 2022 absence of replacement-level capability.

Limitations

  • The cited tests are restricted tax-law tasks, not accountant replacement evaluations.
  • Earlier failures cannot automatically be carried forward to the post date.
  • The claim leaves jurisdiction and acceptable reliability unspecified.

Evidence (2 items)

  • Context only: arXiv,

    nearly at-chance

    Why it matters here: The sentence describes the earlier benchmark's weak neural baselines; the 2021 paper also reports improvements from added structure. These results motivate the concern but do not establish the capabilities of every relevant system in October 2022.

  • Context only: arXiv,

    hand-constructed Prolog-based system

    Why it matters here: A symbolic system could solve this restricted task after people encoded the law. This is material evidence against interpreting Marcus as denying all automated tax reasoning, but it does not meet the autonomous reading and replacement standard.

What would settle it

A contemporary capability survey or representative evaluation of systems available by October 16, 2022, testing autonomous tax-law judgment at a professional reliability standard.
