Italian-American physicist and microprocessor pioneer who led the design of the **Intel 4004** (1970–71) — the first commercial microprocessor — executing its silicon-gate, transistor-level circuit design, and who later founded Zilog and co-created the Z80. In the vault he is the spine of a second thread entirely: the engineer who built the first microprocessor's circuits and then argued, decades on, that classical silicon computation can *never* produce consciousness. With physicist [[entity-giacomo-mauro-dariano|Giacomo Mauro D'Ariano]] he co-developed **Quantum Information Panpsychism** (QIP), the position that qualia require private, non-clonable quantum states — something classical, freely-copyable computation structurally lacks. His 2024 book *Irreducible* (not 2021 — that was his memoir *Silicon*) is the popular statement of the view.

## Updates
- 2026-08-07: Page created at promotion of the *Irreducible* quote-verification capture. QIP confirmed as his and D'Ariano's own primary-sourced term ([[claim-quantum-information-panpsychism-is-dariano-and-faggins-own-term]]); *Irreducible*'s date corrected to 2024 ([[claim-faggin-irreducible-published-2024-not-2021]]); the "silicon…transmute into qualia" line reframed as a likely reviewer paraphrase ([[claim-silicon-transmute-qualia-line-is-a-reviewers-paraphrase]]).
