Capability, adoption, and timing

A related breakthrough is not automatically fulfillment. Review must check the actual capability, how widely it was required to be used, the specified technology, and the original deadline. A prototype cannot establish a claim about routine or widespread use.

Research notes & history

Assessment is conditional on the stated criterion and population. Documented examples establish availability, not universal adoption. The original book edition has not been independently collated.

Open questions

  • Original-edition collation remains an attribution task; it does not erase the stated outcome assessment.

Review history

— Evidence v0.2: PENDING. A future numerical hardware forecast with an unresolved brain-equivalence interpretation. Do not use model marketing or a single low-precision accelerator specification to declare it already fulfilled. Change: Complete deadline/current outcome assessment under explicit scope; separate uncertainty from verdict.

— Evidence v0.3: EDITORIAL_ASSESSMENT_COMPLETE; supplied verdict PENDING. The 2029 forecast has not matured. Checked consumer hardware does not currently reach the stated arithmetic scale. This is pending, not failed in 2026.
