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

“In any case, what I’ve found amounts to a total mismatch between the so-called “rapid buildout” of AI data centers and reality.”

Where Are All The Data Centers?, paragraph 135.

Our reading:

The claimed rapid buildout of AI data centers does not match reality.

Assessment: Unresolved

What happened

Was it true for the period described?

Outcome: Unresolved

We checked, and the evidence so far doesn’t settle it.

Judged on a plain reading. They named no measure, so we used the reading a typical informed reader would take. It is spelled out under “How we judged it”.

Evidence up to . Checked .

Why

Sightline reports that 26% of expected capacity in its tracked data-center and AI-factory pipeline slipped in 2025 [e3]. CBRE reports that primary North American data-center supply grew 36% year over year to 9,432 MW in 2025 [e4]. These records show delays alongside substantial growth, but neither matches AI-specific delivery promises to usable capacity commissioned by those deadlines [e3, e4]. They therefore neither establish nor refute the claimed mismatch through May 12, 2026 [e3, e4].

Caveats

  • Both datasets cover broader categories than AI-only capacity.
  • The evidence does not provide a matched project cohort covering October 2023 through May 12, 2026.
  • Forecast delays for year-end 2026 do not establish missed deadlines by May 12.
  • The claim gives no numerical threshold for a material mismatch.

Evidence (2 items)

  • Context only: Sightline Climate, now Currence,

    26% of expected capacity slipped

    Why it matters: The tracked large-facility pipeline shows real delivery slippage. It combines data centers and AI factories, so it cannot by itself establish the claimed AI-wide mismatch.

  • Context only: CBRE Research,

    36% year-over-year

    Why it matters: Substantial realized supply growth cautions against equating delays with little actual buildout. The series covers primary North American data center markets and does not isolate AI capacity or match it to original promises.

Where we had to interpret

  • The ordinary factual reading is that usable AI capacity is coming online materially more slowly than public buildout claims imply.
  • The contextual construction cycle runs from October 2023 through May 12, 2026.
  • Compare announced delivery with actual commissioning for the same projects and dates. Do not treat all announced future capacity as already overdue.
  • The speaker supplies neither a numerical shortfall threshold nor a defined set of public claims.

Right if: Broad, matched records show a material shortfall between AI capacity publicly represented as deliverable by specified dates and usable capacity actually commissioned by those dates.

Wrong if: Broad, matched records show that actual usable AI capacity substantially tracks the delivery pace represented in public claims.

We wrote this test after the outcome was known.

What would settle it

A defined, broadly representative cohort of AI data-center announcements with original delivery dates and verified usable capacity commissioned by those dates through May 12, 2026. Records must distinguish campus phases and use consistent power measures.

    The final check failed: a cited source didn’t say what the write-up said, and our summary didn’t match their words.
