Thank you for mentioning this - there's a perception that CS and tech has always been male dominated, but there were plenty of women programmers in the 80's and the field has become even more male-dominated since. It's really annoying that one of the primary qualifications for tech CEO's is apparently 'be a tall man, ideally white but Asian is OK too'
"In the United States, the number of women represented in undergraduate computer science education and the white-collar information technology workforce peaked in the mid-1980s, and has declined ever since"
