From George Anders 2015 column in Forbes magazine.
Stewart Butterfield, Slack’s 42-year-old cofounder and CEO, whose estimated double-digit stake in the company could be worth $300 million or more. He’s the proud holder of an undergraduate degree in philosophy from Canada’s University of Victoria and a master’s degree from Cambridge in philosophy and the history of science.
“Studying philosophy taught me two things,” says Butterfield, sitting in his office in San Francisco’s South of Market district, a neighborhood almost entirely dedicated to the cult of coding. “I learned how to write really clearly. I learned how to follow an argument all the way down, which is invaluable in running meetings. And when I studied the history of science, I learned about the ways that everyone believes something is true–like the old notion of some kind of ether in the air propagating gravitational forces–until they realized that it wasn’t true.”
