Timeline 2004–2014: the decade when each of the three historically-expensive parts independently got cheap

Summary

Timeline of the three drivers converging (2004–2014):

Source: Synthesis of the dated atomic entries above.

Confidence: Verified (each dated entry).

Why this matters for Candid: The decade 2004–2014 is when each of the three historically-expensive parts independently got cheap. This is the spine of R1 — Anchor the falling-cost case on the decade 2004–2014 (infrastructure + parts + data); AI-assisted coding is NOT the spine and the reason the falling-cost case does not depend on AI-assisted coding. See R2 — Keep AI-assisted coding at the margin; it lowers assembly labor recently but is not a structural driver.
