Each speed tier follows a predictable ~10-year lifecycle:
Years 0-2: INTRODUCTION - Standards ratified, samples shipping, $$$$ pricing
Years 2-4: GROWTH - Volume ramps, multiple vendors, pricing drops 40-60%
Years 4-6: MAINSTREAM - Peak shipments, broad adoption, pricing drops another 30-50%
Years 6-8: MATURITY - Pricing floor, commoditized, Chinese competition dominant
Years 8-10: DECLINE - Next-gen overtakes, volumes drop, maintenance-only
Years 10+: LEGACY - Minimal shipments, long-tail demand
