Let's play a game, you name a 80s geek hero movie for every 80s action hero movie I name, ok?
Do we have to start or do you agree that I win?
Yes, there were a few "geeky" movies. But claiming that they have anything to do with women avoiding computer science is ridiculous. If anything, the 80s movies were misogynic in general. Women were stereotypically abused as either the love interest for the hero, the dumb idiot that gets the hero in trouble or needs to be rescued by him or the inefficient example of how women just can't do what the hero later has to fix.
Women in anything but romance/love stories were basically the same as geeks in 80s movies: The bumbling idiot that makes the hero look so much better.
