EXPONENTIAL ASCENT · SATURATION CEILING · S-CURVE MODEL
DOUBLING EVERY 5.9 MONTHS → PLATEAU AS COMPUTE LIMITS BIND
"Just like Moore's Law, we saw the doubling in performance every 18 months with AI. We have now started to see that doubling every six months or so." — Satya Nadella, CEO Microsoft, Ignite 2024
This model begins with Nadella's reported 5.9-month doubling cadence from a baseline of 10 units in May 2025. But raw exponential growth is modified by an S-curve (logistic) ceiling — reflecting the eventual exhaustion of low-hanging software gains and society's unwillingness to build arbitrarily more compute. Growth slows as it approaches the saturation limit; use the slider to explore different timelines. TODAY (May 2026) sits at roughly 2 doublings in — still in the steep exponential phase.
