x = years before 2026 the technology appeared, y = years it took to reach most of humanity
source: Same 11 estimates and sources as adoption-10k-years.pages.dev (Our World in Data/ITU, World Bank, GSMA, archaeology refs; tech list Lipsey, Carlaw & Bekar 2005 via Wikipedia) • transform: Teal = measured, amber = reasoned bracket, pink = not yet a majority (not in fit). Fit: straight line in log(years taken) vs log(years since it appeared). Catch: every point must sit below the red dashed ceiling, and each tech took 31-99% of its age; random fractions in that range give R² about 0.98 on these axes, so the straightness is mostly built in. • drawn 2026-10-21 01:41 UTC
