It really doesn't. Unless you seriously think punch card programming is the same as modern programming, or that the fact that only women were secretaries that did programming somehow provides data on the relative strengths and inclinations of women and men for programming work at that time.
Look, it's clear that you have no idea of the breadth and depth of data available on this subject, and a trite "sexism/oppression" narrative explains hardly any of it. For instance, the fact that as a nation becomes more egalitarian, the gender disparities in STEM increase, ie. Nordic countries have worse gender disparities than here, despite having less sexism, and oppressive countries like Iran actually have gender parity in STEM fields.

The fact is, there's good evidence that women are naturally less interested in STEM-like fields due to a well known psychological attitude on things vs. people. That attitude explains facts like why medicine and law have achieved approximate gender parity overall, but surgery is still dominated by men, pediatrics and family law is dominated by women.
