"From 1984 to 2006, the number of women majoring in computer science dropped from 37% to 20% — just as the percentages of women were increasing steadily in all other fields of science, technology, engineering, and math, with the possible exception of physics. The reasons women left computer science are as complex and numerous as why they had entered in the first place. But the most common explanation is that the rise of personal computers led computing culture to be associated with the stereotype of the eccentric, antisocial, male “hacker.” Women found computer science less receptive professionally than it had been at its inception.
Why do we care about a long-gone moment in early computing history when the presence of women was unexceptional?
Because it looks like women are now returning to computer science."
