El Capitan beat Kurzweil’s 2005 supercomputer forecast by a factor of 5,000. Your desktop missed it by one hundred.
Kurzweil’s 2005 computing predictions split along a clean line: bolt a computer to a face and it ships; bolt one to a star and twenty-one years of exponential scaling has not moved it.
Kurzweil listed exotic computing substrates in 2005 as heirs to silicon. Twenty-one years on, silicon won by getting weirder — and his lone forward bet, that quantum stays special-purpose, has aged best of all.
Ten 2005 predictions about transistors, DNA computing, autonomic systems, battlefield networks, and cosmic compute limits — scored against 2026 reality.
Kurzweil’s curve kept bending. Almost none of the specific mechanisms he nominated to keep it bending actually arrived.
Kurzweil predicted molecular computing as the sixth paradigm. What arrived was 3D-stacked silicon, reversible logic startups, and an AI power crisis nobody saw coming.
