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

“A rack of Vera Rubin or Blackwell GPUs will cost as much to run in five years as they do today, as will an incomplete data center cost just as much to finish construction, connect to the grid or acquire behind-the-meter (IE: generators) power for.”

AI Doesn't Have ROI, paragraph 53. The full statement is at the source.

Our reading, the sentence that was checked:

In five years, a rack of Vera Rubin or Blackwell GPUs will cost as much to run as it does today, and unfinished data centers will cost as much to complete and power.

From the speaker

  • A rack of Vera Rubin or Blackwell GPUs
  • will cost as much to run in five years as they do today
  • an incomplete data center
  • cost just as much to finish construction, connect to the grid or acquire behind-the-meter (IE: generators) power

Our interpretation

  • Five years is measured from June 2, 2026, giving a June 2, 2031 comparison date.
  • As much is read as no material reduction, rather than exact equality to the cent.
  • The comparison concerns the same rack generation and configuration at comparable utilization and service levels, not the cost per token of newer hardware.
  • The unfinished-facility comparison holds location, remaining construction scope and required power capacity comparable.
  • The ordinary reading uses nominal costs in the same currency. Currency, inflation treatment and accounting basis are not specified.
  • I apply the five-year comparison to both clauses. No separate requirement that the bubble first burst is stated in this sentence.

Counts as supported if: Comparable June 2031 records show no material reduction from June 2026 in both rack running costs and the costs of completing and powering comparable unfinished facilities.

Counts as contradicted if: Comparable June 2031 records show materially lower running costs for the specified racks or materially lower completion and power-provision costs for comparable unfinished facilities. Divergent results across components would require a mixed assessment.

Prospective: these criteria were frozen before the deadline, while the outcome was not yet public.

Current assessment

Did the forecast come true?

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 comparison falls due on June 2, 2031. No decisive event fixes the relevant future costs. Current construction forecasts and hardware efficiency claims cannot establish what the same racks and comparable unfinished facilities will cost then.

Limitations

  • The two cost components need separate matched measurements.
  • The unknown accounting basis prevents a decisive money comparison without further clarification.
  • Lower cost per unit of computation would not necessarily mean lower absolute rack running costs.

Evidence (1 item)

  • Context only: JLL,

    average global cost

    Why it matters here: This is a forecast for 2026 shell-and-core construction costs, not an observed 2031 outcome. It excludes tenant technology fit-out and does not match the full completion-and-power comparison.

What would settle it

Matched June 2026 and June 2031 records for rack operating bills and comparable facility completion and power costs, using explicit cost boundaries and accounting treatment.
