Steven Levy, writing on Wired around 30 years ago on the rise of spreadsheets:

Increasingly, however, businessmen are not telling but letting their spreadsheets do the talking. Because a spreadsheet looks so authoritative – and it was done by a computer, wasn’t it? – the hypothetical models get accepted as gospel. The spreadsheet presentation is becoming both more commonplace and more sophisticated: not only the numbers but the formats of the sheets themselves are designed to make eloquent points. This use of spreadsheets has less to do with productivity or insightful analysis than with the art of persuasion. “People doing negotiations now sit down with spreadsheets,” Bob Frankston said. “When you’re trying to sell a car, the standard technique is to ask for the other person’s objections, and then argue them away. If two people are in front of a spreadsheet, and one says, ‘Well, the numbers say this,’ the other can’t say, ‘Yes, but there’s something I can’t quite point to.’”
