Kurzweil said the brain’s design fits in less than Microsoft Word. Twenty-one years later, the genome held the line. Word did not.
-
Kurzweil pointed at the wrong telescope, the wrong observatory, the wrong funder — and the right capability.
-
Kurzweil called the curves on connectomics and brain decoding. He missed on the wires — optic nerve, spindle cells, and millisecond fMRI.
-
Carbon nanotubes were supposed to replace silicon. The Internet was supposed to route around failures. Both bets aged badly.
-
The 2020s were supposed to inflect life expectancy upward. They didn’t. But the molecular machinery Kurzweil predicted just entered human trials.
-
GPT-4.5 passed a three-party Turing test in 2025 — four years ahead of Kurzweil’s 2029 bet. But the machine that crossed the line was not the one he predicted would.
-
Twenty years after Kurzweil predicted detailed models of hundreds of human brain regions by 2025, the deadline has arrived — and the delivery looks nothing like what he described.
-
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.
-
Kurzweil said global brain observation would arrive in the 2020s. In September 2025, 621,733 neurons across 279 brain areas, in Nature. Twelve neuroscience predictions, scored.

Kurzweil said we wouldn’t need to map every connection in the brain. The connectomics field disagreed and just spent a decade doing exactly that.
