The world at the time.

Watkins collected technical forecasts for a December 1900 Ladies' Home Journal article about the next century. Wireless telegraphy and experimental wireless voice systems gave this forecast a technological starting point.

What happened.

Wireless telephony became practical and eventually global through mobile networks, with ITU reporting more than 740 million mobile phones in use by the end of 2000. The central capability existed by the deadline, although worldwide calls commonly combined radio links with wired infrastructure.

The counter-signal.

An archived September 1900 account described wireless voice apparatus as crude and still awaiting larger machines and rigorous tests. That contemporary gap matters: experiments did not yet establish a dependable global service.

Verdict.

Reasoning: sound · Outcome: right

The claim succeeds as a forecast of global wireless access, not as a claim that every intermediate circuit would be wireless. Its century-long horizon also allowed several different technical architectures to satisfy the prediction.

Exact excerpt is from the archived original article; month known but date field deliberately year-only. The source documents ship-to-shore voice in 1919 and cellular demonstration in 1973; global-service interpretation is editorial.

Cause of death / explanatory lens.

No cause of death assigned

The lesson.

How much does a long horizon compensate for an immature mechanism?
