1.Bloc 1 - Fundamental ConceptEasy· Physical electricity capacity
What physical substrate is primarily required to support the exponential growth of artificial intelligence and hypersonics, demanding actual megawatts rather than financial liquidity?
2.Bloc 1 - Fundamental ConceptEasy· Foreign-exchange reserves
What percentage of global foreign-exchange reserves did the U.S. dollar approximately account for in 2025, providing unparalleled liquidity for global contracts?
Under the Triffin Dilemma (1960), a country supplying the global reserve currency must run persistent current account deficits. What is the inevitable long-term consequence for the reserve currency's value?
Based on the Exorbitant Privilege (Giscard d'Estaing 1965), the U.S. avoids balance-of-payments crises primarily because it can perform which unique macroeconomic function?
6.Bloc 2 - Academic TheoryMedium· Energy Return on Investment (EROI)
Assuming the Energy Return on Investment (EROI) framework, if the energy required to extract critical minerals for grid storage exceeds the energy stored, what happens to net energy?
How do decade-long permitting bottlenecks for new transmission lines directly undermine the strategic concept of Energy Darwinism in the context of rising AI compute demand?
8.Bloc 3 - Contextual ApplicationHard· AI compute demand
Given the exponential growth in AI compute demand, how does the resulting electron gap challenge the assumption that financial liquidity alone can secure technological dominance?
9.Bloc 4 - Expert SynthesisExpert· Triffin Dilemma (1960) vs Energy Return on Investment (EROI)
How does the Triffin Dilemma (1960) contrast most sharply with Energy Return on Investment (EROI) when evaluating whether financial liquidity or physical energy surplus dictates long-term hegemonic survival?
10.Bloc 4 - Expert SynthesisExpert· Hegemonic Stability Theory (Kindleberger 1973) vs Exorbitant Privilege (Giscard d'Estaing 1965)
Hegemonic Stability Theory (Kindleberger 1973) and Exorbitant Privilege (Giscard d'Estaing 1965) differ most sharply on whether the global reserve currency acts primarily as a public good or what?
