Here’s an example of what Andrew McAfee wrote about tech toys of the rich becoming tools of the masses: An article from Peter H. Lewis in the July 19, 1992 New York Times, which was prescient about the emergence of smartphones (if a decade too early), without realizing they’d be for everyone. Andy Grove, quoted in the piece, thought it all fantasy. An excerpt:

Sometime around the middle of this decade no one is sure exactly when — executives on the go will begin carrying pocket-sized digital communicating devices. And although nobody is exactly sure what features these personal information gizmos will have, what they will cost, what they will look like or what they will be called, hundreds of computer industry officials and investors at the Mobile ’92 conference here last week agreed that the devices could become the foundation of the next great fortunes to be made in the personal computer business.

“We are writing Chapter 2 of the history of personal computers,” said Nobuo Mii, vice president and general manager of the International Business Machines Corporation’s entry systems division.

How rich is this lode? At one end of the spectrum is John Sculley, the chief executive of Apple Computer Inc., who says these personal communicators could be ‘the mother of all markets.’

At the other end is Andrew Grove, the chairman of the Intel Corporation, the huge chip maker based in Santa Clara, Calif. He says the idea of a wireless personal communicator in every pocket is “a pipe dream driven by greed.”
