#!/usr/bin/env python3 """ Successive Technology Cycles Compress -- Inventory Prediction #22 Prediction: Each successive major technology cycle is shorter than the previous one, because learning curves accumulate and alpha_eff increases. Paper 6 (AI Transition), Corollary "Duration compression": τ_{n+1}/τ_n ≈ (α_n/α_{n+1}) · [competition ratio] Qualitative prediction (marked "Q" in prediction inventory). Lean: CESProofs/Hierarchy/TransitionDynamics.lean transition_duration_scaling [axiom] -- T ~ O(1/sqrt(eps_drift)), Neishtadt GSPT wright_law_duration [schematic] -- semiconductor 8yr, generic 11yr CESProofs/Dynamics/BusinessCycles.lean canard_delay [proved] -- positivity of 1/sqrt(eps * Tdot) Five subtests: 1. Wright's Law Duration Formula (N=12 technology eras): τ ~ ln(cost_ratio) / α. Tests whether α × τ_wave correlates with ln(cost_ratio), the QUANTITATIVE prediction from the formula. 2. α-vs-Duration Spearman (N=12 technology eras): Higher learning rate α predicts shorter wave duration. 3. Geometric dimension mediation (N=12): d=2 (planar) technologies have shorter cycles than d=1 (assembly) controlling for cost reduction magnitude. 4. Technology diffusion speed compression (N=11 US technologies): Newer technologies reach 25% household adoption faster. 5. Technology diffusion speed with GDP control (N=11): Same as #4 but residualized against GDP per capita at launch year. Data: wave_learning_rates.csv (12 eras with α, d, wave_duration, cost_ratio), household adoption data from Census/CPS/FCC/Nielsen/Pew, Maddison GDP. Review Notes (2026-03-12) ------------------------- Theory match: CORRECT - Subtests 1-3 test quantitative duration compression across 12 eras. - Subtests 4-5 test a corollary: newer technologies diffuse faster, with and without GDP per capita control. I/O audit: CORRECT - All subtests: α or time index → duration/adoption lag (correct direction) Data-signal alignment: ADEQUATE to STRONG - wave_learning_rates.csv: 12 eras with published α estimates, N=12 - Diffusion data: Census/CPS household surveys, N=11 - GDP control uses Maddison Project historical estimates Code quality: CLEAN Confidence in verdict: MEDIUM-HIGH — N=12 eras gives adequate power; quantitative formula test is genuinely falsifiable """ import sys, os sys.path.insert(0, os.path.join(os.path.dirname(__file__), '..', '..')) import numpy as np from math import factorial from itertools import permutations from scipy import stats from common.stats import log_result, spearman_test from common.data import load_compiled _cache = {} # populated by main(), used by figures() # Technology diffusion speed: years from commercial launch to ~25% US # household penetration.
