"This is a gem that will shape your way of seeing and thinking about the world forever. Rich was one of the true visionaries of Xerox PARC and this unique book, in both its form and content, provides a window into a brilliant and incredibility imaginative mind at work."

Publishers Weekly review:

The Plenitude is the word of Silicon Valley polymath Gold for the limitless stuff produced to feed our consumer-focused economy, but this small, posthumous (Gold died in 2003) book reads more like his private notebook than a business guide. That's not a bad thing: Gold, a scientist, inventor and artist who worked at times for the toy company Mattel and the legendary Xerox PARC research labs, is good company. Based on a few of his lectures, this breezy book shares thoughts on creative hats Gold has worn, such as artist and engineer, and the worldviews they impose on practitioners (e.g., engineers like to solve problems while designers are contemptuous of artists for their detachment from the commercial). The later part of the book weighs consumerism's pros and cons, coming out in favor—where else could an inventor fall?—while offering valid critiques (e.g., so much of what we make and buy is ugly). Throughout, Gold displays casual insights—such as illustrating the sheer abundance of the plenitude by pointing out the variety of shirts in an audience and the work that went into each—and pads this very skinny book with his own goofy cartoons. The result is a fun splash in some of the important ideas behind modern consumption.

MIT Press has the table of contents and sample chapters here. The book was reviewed last month in the LA Times:

This little book, with its simple logic and language and unforgettable, whimsical drawings, will change the way its readers look at the world around them.
