Our reading of the claim

Reference (stated reasonable reading)

Late

Criterion: Internet volunteers pool unused computation into virtual parallel systems reaching the stated approximately 20-petaflop scale.

Deadline: 2009 · Included in this comparison

At original deadlinePARTLY FULFILLED
By review dateFULFILLED

Volunteer computing was already real, but the 2010 retrospective’s cited throughput was below the 20-petaflop target. Folding@home’s documented 2020 exascale aggregate easily exceeds that numerical threshold. It remains distributed task throughput, not a single brain emulator.

Deadline and follow-up notes

At deadline: Volunteer computing was already real, but the 2010 retrospective’s cited throughput was below the 20-petaflop target.

By review: Folding@home’s documented 2020 exascale aggregate easily exceeds that numerical threshold. It remains distributed task throughput, not a single brain emulator.

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.

Alternative interpretation: 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.

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.
  • An earlier documented instance could refine timing; the documented-by date is not claimed to be the invention year.
