Kurzweil’s curve kept bending. Almost none of the specific mechanisms he nominated to keep it bending actually arrived.
219 US patents for devices that read biomarkers from sweat — a category that barely existed before 2010. Half were granted in the last five years.
In 2024, the USPTO granted 21 patents for materials engineered to radiate heat through Earth’s atmosphere and into the vacuum of space. The technique requires zero electricity. The trick that made it work came from telecom.
Kurzweil bet on rotaxanes, nanotubes, and self-assembling polymers to carry computing past silicon. Twenty years later, only spintronics made it to market — and the brain got matched anyway.
A UCLA psychiatrist patented a device that plays your brain’s own deep-sleep frequency through your skull to clear Alzheimer’s plaque. Behind it: 64 patents, 144 clinical trials, and an FDA-approved device already treating patients.
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.
Kurzweil predicted strong AI via brain reverse-engineering. It arrived via transformers and text. Every destination was right. Every route was wrong.
Kurzweil predicted human-level AI by the mid-2020s. He got the direction right and the mechanism completely wrong.
The solid-state battery story in the US press is QuantumScape’s share price and CATL’s announcements. The patent data tells a different story. Toyota holds 200 of the 1,148 US solid-state battery grants issued since 2020 — 14x QuantumScape, eight times the US pure-plays combined. A slow-walking incumbent is still an incumbent.
