After a multi-pronged search (Pant's own article, Kyle McDonald's site, Wikipedia's
"Low-background steel" article, John Graham-Cumming's blog, lowbackgroundsteel.ai's
About page, and search-engine aggregation), Rajiv Pant's March 2025 essay remains the
only located account for the claim that artist/programmer Kyle McDonald applied the
low-background-steel analogy to AI training data on December 5, 2022. Pant writes:
"Programmer and artist Kyle McDonald made a similar observation in an X (formerly
Twitter) post on December 5, 2022, noting that just as particle detectors require
special steel manufactured before nuclear contamination, future AI might need
training data collected before 2022." The archived copy of Pant's page, fetched
directly rather than via a search summary, contains no hyperlink to the post and no
quotation marks around the sentence. Every other page repeating the claim traces back
to this same unlinked sentence; none add an independent trace to McDonald's own text.

The account also carries internal signs of being written from recollection rather than
from a document open in another tab. Discussing Graham-Cumming's own earlier tweets on
the same analogy one paragraph earlier, Pant flags that "his specific tweet on this
subject is no longer available" — an explicit caveat about access. No comparable
caveat, link, or quotation mark accompanies the McDonald claim that follows it, and the
prose pattern ("made a similar observation... noting that...") reads as characterization
rather than transcription. This bears on
[[claim-low-background-steel-ai-metaphor-predates-graham-cummings-site]], which uses
McDonald's account as part of its case that the metaphor "emerged organically" rather
than originating with [[entity-john-graham-cumming|Graham-Cumming]]: that evidence leg
is exactly as strong as [[entity-rajiv-pant|Pant]]'s unlinked paraphrase, no stronger.

> McDonald's — not because he checked it, as far as this search can tell, but because
