Nine of ten plasticity findings Kurzweil cited in 2005 held up. The reverse-engineering synthesis they were supposed to enable did not.
Kurzweil’s 2005 brain-scanning scouting report named specific labs. The milestones mostly arrived — through different teams entirely.
Kurzweil’s 2005 neuroscience facts held up. His fMRI and MEG specs got beaten — by instruments he didn’t name.
Nine of ten neuroscience claims from 2005 held up. The tenth — brain scanning doubling yearly — hit the physics of blood flow and skulls, and Kurzweil concedes it in the 2024 book.
Nine of ten nanotech milestones Kurzweil cited in 2005 were real. Almost none reached a product through the mechanism he named.
Kurzweil forecast diamondoid respirocytes in bloodstreams by the 2020s. What arrived instead is a 1.8-millimeter magnetic microrobot entering human trials in 2026 — right direction, wrong scale by three orders of magnitude.
The 2005 genetics chapter got the timelines mostly right. It got the machines, companies, and methods mostly wrong.
Of ten nanotech-for-the-environment predictions from 2005, the one with no named material — better lighting saving 200 Mt CO2/year — blew past its number by 2x. Almost every specific mechanism stayed in the lab.
Kurzweil bet on hydrogen cars, microbial cells, and sonofusion in 2005. Silicon photovoltaics quietly won everything.
Kurzweil bet on methanol laptops and coal with sequestration; lithium-ion won, FutureGen died, and the distributed fuel cell is booming — just inside AI data centers.
