The widely-circulated 'silicon will never transmute into qualia' line attributed to Faggin's *Irreducible* is most likely a reviewer's paraphrase, not the book's wording

The sentence "The electrical signals of silicon will never transmute into qualia" — repeated across secondary summaries and AI-search results as if it were a direct quotation from Federico Faggin's book Irreducible — traces to a single identifiable origin: Colin W. P. Lewis's August 2025 review essay on onepercentrule.substack.com. In that essay the sentence appears in the reviewer's own running prose, carrying neither quotation marks nor a "he writes"/"Faggin says" attribution, unlike other sentences in the same piece that are explicitly marked as direct quotes ("'More cannot come out of less,' he writes"). That structural asymmetry is a signal the line is the reviewer's paraphrase of Faggin's position, not a transcription of the text.

An independently-sourced review — Frank S. Robinson's in Philosophy Now Issue 170 (2025) — quotes the book on the same point with a page citation (p.9), and the wording differs materially: "I could not find any way to convert the electrical signals of the computer into qualia, because qualia belong to a different kind of reality with no apparent connection to symbols." This is first-person and confessional ("I could not find any way"), refers to "the computer" rather than "silicon," and lacks the flat "will never" declarative framing. Two Goodreads reader-quote pages for the book contain no instance of "silicon," "qualia," or "transmute" — weak corroborating, not dispositive, negative evidence.

The line captures Faggin's argument accurately in substance; what is in doubt is only whether it is his wording. This note inherits an [unverified-quote — needs direct read] flag against the primary book and stays seedling, routing its verification to question-verify-faggin-irreducible-qualia-quote. It is the correction that most directly revises claim-faggin-4004-designer-argues-classical-silicon-cannot-be-conscious, which had inherited the Substack line as its anchor quote.
