Grew up with Atari 800xl in 1980s in communistic Poland and confirm the same. It is quite obvious what happened but first what I really don't like about the article: Object ovation of women. You have "agents" who decide for themselves -- men -- and objects who need to be told/encouraged or have stuff explained as otherwise they will apparently not understand why they should study CS. Or have mammography ( when was the last time you seen an ad explaining men to have prostate checked? ), participate in politics, etc? You don't tell agents what to do. Agents take action by the definition of being an agent. Objects on the other hand need to be told. Feminism is objectifying women this way.

And explanation of why not these many women are in the CS percentage wise today as in 1984? Easy. As CS became very popular instead of being highly scientific niche subordinate to mathematics department, it just became as any other engineering department - overflown with men.

Btw, I studied English language for my Masters. Hihhly recommended : male/female ratio 1 to 7. 😉 And no, there are no articles encouraging men to take foreign languages as their University Major. As we are not objectifying them as feminists are objectifying women. We know that advising agents would be inappropriate. But if you want to spend 4 or 5 years with chicks around you -- go study foreign language. And you can still pick up programming after partying with them for five years 😉
