A simple resolution for the question of this thread is easy: For now, girls tend to pursue what girls do and know that computer science (CS) is for boys and not part of what girls do. So, girls try to avoid CS in college. When they try CS in college, mostly they don't like it. Why don't they like it? Girls are (1) much more emotional than boys, (2) much more social, (3) eager to get praise, acceptance, and approval from others from work that "helps people" in the sense I explained (essentially volunteer work to help suffering people), e.g., one of the daughters of Bush 43 went to Ethiopia, and (4) better at, and more strongly seek, human to human contact. So, on these criteria, girls see that CS is so detailed and technical it seems (1) emotionally cold, (2) not very social, (3) not good for work that "helps people", and (4) not good for human to human contact. So, many girls who try CS soon conclude that they don't like it. For the future, girls who do not want to concentrate on being mommies, unlike for nearly all of history, will be able to so not concentrate and, thus, on average will be removing their genes from the gene pool. What will be left will be genes of women especially determined to be good as mommies and even less interested in CS. You missed it with my: "He's all fired up about the technical topic. Sorry, but boys have strong desires to master any technical topics around them that appear important. In part there is a lot of innate curiosity." Then for my "I'll let you justify that yourself" you didn't! The "technical topics" here are not yet nearly all that would be popular on Hacker News. Instead the topics are whatever are "around them" (the boys as they grow up). So, depending on what they see in their family, adults' careers, neighborhood, community, etc., the topics might be about cars, cattle raising, household electricity, operation of a commercial pizza oven, cardiology, roasting pastrami, trading foreign currencies, computing, etc. Why? The usual explanation is that the boys know that they are small versions of men, that men take competency in their careers very seriously, that they, the boys, do not have such competency, feel vulnerable and out of control from the lack of competency, and, thus, as part of growing up into such competency are eager to soak up everything that is relevant they can. That's the standard explanation. Although you didn't 'get it' the first time I explained it, didn't work it out for yourself, I believe you can understand this point. For whatever reasons, you are straining to disagree with what I wrote. I remember a girl in the fifth grade: Her handwriting was good, and mine, as is common for boys at that age, was poor. So, she looked at my paper and said that she couldn't read it. So, I copied the paper again in block letters, and again she said she couldn't read it. I copied it again in larger, extremely clear block letters, and she gave the same answer. Of course, she was lying and having fun manipulating. You are doing much the same. Enjoy the games of fifth grade girls.
