"Maps are data"

Maps are locations where people store and retrieve information about how the world around them is structured. In what they show and what they don't show, you can see the worldview of the people who created them.

"Data is data" means data is created.

In what it shows and what it doesn't, you can see the worldview of the people who created it. Every data set is like a map of what's important; you can read it like a map for its history.

Don't take data as a given.

Bricklin [Visicalc] enrolled in the Harvard University MBA program, with the aim of equipping himself with a wider skill set than programming—he did not want to suffer the same fate as many programmers he had encountered who had become unemployed in their fifties.

Karpor [Lotus] took several years to mature socially, drifting in and out of transcendental meditation, a period as a disc jockey, and taking a master’s course in psychological counseling. He enrolled for an MBA at MIT’s Sloan School of Management in 1978. In July 1978, he bought an Apple II computer and it was a turning point in his life.

"I know of one venture capital firm that assumes people manipulate spreadsheets," Kapor said. "So they have this other model to put against the first one, to factor the stuff out.
