An anonymous reader writes: A column on the Wall Street Journal argues that sexism in the tech industry is as old as the tech industry itself. At its genesis, computer programming faced a double stigma -- it was thought of as menial labor, like factory work, and it was feminized, a kind of "women's work" that wasn't considered intellectual (Editor's note: the link could be paywalled; alternative source). In the U.K., women in the government's low-paid "Machine Operator Class" performed knowledge work including programming systems for everything from tax collection and social services to code-breaking and scientific research. Later, they would be pushed out of the field, as government leaders in the postwar era held a then-common belief that women shouldn't be allowed into higher-paid professions with long-term prospects because they would leave as soon as they were married. Today, in the U.S., about a quarter of computing and mathematics jobs are held by women, and that proportion has been declining over the past 20 years. A string of recent events suggest the steps currently being taken by tech firms to address these issues are inadequate.
