The bracketed-date phrase "the chain rule (1676), the first NNs (circa
1800), the first practical AI (1914)…" — widely excerpted as
[[entity-juergen-schmidhuber|Schmidhuber]]'s "timeline" of AI history,
including in the vault's own
[[claim-schmidhubers-annotated-history-projects-deep-learning-onto-pre-1900-mathematics]]
— is a single sentence from the Abstract of *Annotated History of Modern AI
and Deep Learning* (arXiv:2212.11279), describing what "a modern history of
AI & ML must emphasize." It is not the wording of the paper's own structural
divisions. The Table of Contents gives Sec. 2 as "1676: The Chain Rule For
Backward Credit Assignment" and Sec. 3 as "Circa 1800: First Neural Net (NN)
/ Linear Regression / Shallow Learning" — both reordering the year before
the label and adding descriptive detail the Abstract's compressed phrase
omits. "The first practical AI (1914)" has no corresponding section title
at all; the 1914 material (Leonardo Torres y Quevedo's chess end-game
automaton) is introduced in the Introduction and elaborated inside the body
of Sec. 18 ("It's the Hardware, Stupid!"), never as its own heading.

The phrase is genuine and verbatim — it is not a fabrication or a drift
of paraphrase — but it is a compression doing double duty as summary,
not the document's own periodization scheme. Anyone citing it as "the
paper's timeline entries" is citing an accurate quotation of an inaccurate
description of the paper's own structure.
