Our reading of the claim

Reference (stated reasonable reading)

Wrong / missed

Criterion: Typical users have at least twelve separately functional worn/carried computing devices linked in a body network.

Deadline: 2009 · Included in this comparison

At original deadlineNOT FULFILLED
By review dateNOT FULFILLED

Contemporary device-ownership surveys show a handful of gadgets, not typical twelve-node body networks. Phones, watches and earbuds create useful small networks, but not typical twelve-device ensembles. This is a medium-confidence prevalence judgment, not a claim that no enthusiast has twelve devices.

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: A phone’s internal chips are not counted as separate body-LAN computers; that redefinition would make the original list of personal functions misleading. No global body-LAN census is available.

Review history

— Evidence v0.2: UNSCORABLE. Counting chips inside a phone is not the same as counting independently networked worn devices. The legacy paraphrase removed both the numerical threshold and body-LAN condition. No stable counting convention is specified. Change: Complete deadline/current outcome assessment under explicit scope; separate uncertainty from verdict.

— Evidence v0.3: EDITORIAL_ASSESSMENT_COMPLETE; supplied verdict WRONG. Contemporary device-ownership surveys show a handful of gadgets, not typical twelve-node body networks. Phones, watches and earbuds create useful small networks, but not typical twelve-device ensembles. This is a medium-confidence prevalence judgment, not a claim that no enthusiast has twelve devices.
