AI-Fizzle Sub-World 1B: Energy, Semiconductor Fab & Economic ROI Exhaustion (1.3%)

Logarithmic scaling laws require exponentially costly $1T+ power and chip clusters for marginal gains, causing the AI capex bubble to deflate into steady utility.

In this sub-variant of AI-Fizzle (44% of the AI-Fizzle branch → 1.3% overall), capability gains remain strictly logarithmic in compute while electrical grid buildouts, lithography limits, and inference energy costs scale linearly or worse. Capital markets pull back from $1T+ training runs, and AI settles into a mature utility industry akin to commercial aviation.
Verification Note: Models the thermodynamic and capex diminishing-returns path to AI-Fizzle.
Operationalized Forecast Question (exclusive_branch)Horizon: 2050-01-01

Will energy and capex diminishing returns stall frontier AI scaling well below AGI before 2050?

Resolution Criteria: Resolves YES if AI-Fizzle occurs primarily due to economic and thermodynamic scaling limits.

Logarithmic capability returns vs. exponential energy and fab costs could stall frontier training runs once clusters require >15 GW of dedicated baseload.

If each linear step in reasoning reliability requires 10x more test-time and training FLOPs, macroeconomic ROI could flatten out before full AGI, turning frontier AI into a mature utility like commercial aviation.
