Our reading of the claim

Reference (stated reasonable reading)

Correct

Criterion: The pocket/worn personal computers in the surrounding passage generally use electronic storage rather than rotating media.

Deadline: 2009 · Included in this comparison

At original deadlineFULFILLED
By review dateFULFILLED

Flash-based phones and small music players fit the devices described in the passage by 2009. This remains a full success for that device class. Buttons, haptic motors and exceptions do not defeat “for the most part.”

Deadline and follow-up notes

At deadline: Flash-based phones and small music players fit the devices described in the passage by 2009.

By review: This remains a full success for that device class. Buttons, haptic motors and exceptions do not defeat “for the most part.”

Most personal computing devices have no moving parts.

How My Predictions Are Faring — Ray Kurzweil

1999 · Attribution / year unconfirmed
The Computer Itself, prediction 6, printed p. 15

AUTHOR RETROSPECTIVE REPRINT

Source publication: 2010-10 · Access: text checked

Reprinted forecast passages are used for attribution; the author’s favorable self-grades are not independent outcome evidence. Original book editions were not inspected.

CONTEXT · 2008-07-14

iPhone App Store downloads top 10 million (opens in a new tab)

Opening announcement and descriptions of wireless application downloads and Multi-Touch features. The release establishes downloadable applications on iPhone/iPod touch and their touch interface. Evidence limits: It does not establish storage technology or the absence of moving components; see the added flash-player source.

SUPPORTS · 2005-01-11

Apple introduces iPod shuffle (2005) (opens in a new tab)

USB flash-drive paragraph and Pricing & Availability section. Apple documents a shipping flash-storage player in January 2005. Interpreting flash storage as avoiding mechanical disk storage supports the portable-device criterion. Evidence limits: This is an editorial inference about storage; physical switches remain, and the source does not establish a majority across all personal devices.

Source checked as of 2026-10-18
PRIMARY PRODUCT RELEASE

Source publication: 2005-01-11 · Access: primary page text checked

Documents a USB flash-storage music player and immediate shipping. Flash storage supports an absence of mechanical storage, not the absence of all physical switches.

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.

i
Alternative interpretation: The reference does not extend a contextual claim about truly personal devices to servers. Current cumulative fulfillment does not mean every laptop or computer is fanless.

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.

Review history

— Evidence v0.2: UNREVIEWED. Phones and notebooks cannot be silently combined or separated to obtain a favorable majority. Apple’s 2008 Air still offered a hard disk as well as an SSD option. A sales/installed-base denominator is needed. Change: Complete deadline/current outcome assessment under explicit scope; separate uncertainty from verdict.

— Evidence v0.3: EDITORIAL_ASSESSMENT_COMPLETE; supplied verdict CORRECT. Flash-based phones and small music players fit the devices described in the passage by 2009. This remains a full success for that device class. Buttons, haptic motors and exceptions do not defeat “for the most part.”

— citation-supplement-2026-10-18: 2 primary citation checks/additions. Primary citation locators, source-specific support limits and additional corroborating references; no changes to verdicts, eligibility or timing judgments.
