That wasn't the reality of it, of course. Those women were doing massive amounts of the work around the logic of the systems.
But there was a hierarchy, and everyone knew it. Wasn't until the 70s and 80s that things turned into a man's world. Once people figured out that there were hard problems to solve and plenty of opportunities to yell, "Yeah! We Really Fucked that problem in the ass!" Yeah, right about that time, the women started leaving.
My mom's roommate didn't quit NASA until she retired quite nicely in 1995. And by that time it was a very different place.
You can laugh and mock someone who started with punch cards all you want, and maybe even think she's a dinosaur who didn't keep up. But this woman taught me assembly, C, Lisp, C++, SQL, and Python. Not too shabby for a punchcard programmer from the 50s. I'd say she kept up just fine.
But boy, did she want out of that environment. She was not a happy camper by the time the 90s rolled around.
The thing you aren't getting is that it's the people on the ground who did a lot of the work to make programming languages not suck.
In fact, it was almost embarrassing for a man if he knew how to type since that was women's work.
So I'm sure that played a role once keyboard came into the picture.
Before that, when it was mostly punchcards, women were manual "computers" that did the calculations. So it seems reasonable that computers were considered women's work and thus that drive the trend.
Whether women were more or less suited to the job wouldn't seem to be relevant at the time.
I would say "more or less preferred" is a more relevant and less acerbic metric to consider.
I think James Damore's main thesis (or one of his main theses) was that men had more of a natural and biologically driven preference to work with things/machines. So if women were placed in these positions, it detracts from the narrative that "something mysterious happened in the 80s that caused women to flee the computer industry".
When ceos started realizing the potential social and economic power of the magic typing box it was no longer socially taboo for men to operate them. Of course, no self respecting business elite man would use one, only dirty hippie social rejects.
That's what makes the whole thing extra sad. For the longest time silicon valley types had to deal with being social outcasts in the business world. Rather than learn from that to be more inclusive they just took up the mantle of the business elite they replaced and perpetuated the same system of prejudice. In fact now that I think about it part of excluding women from the profession might have been an attempt at self preservation. Early tech people knew they were already looked down upon, if they didn't amp up the sexism to make it clear they were real men they would look even weaker to their east coast elite superiors.
No, that's not what I'm saying at all. It doesn't matter how well they "performed". What matters is: would they have chosen that profession if they weren't placed there? Could it be that men preferred computer-related careers more than women did? If so, then the fact that many women were placed in those careers initially is completely irrelevant to the question of why there aren't a lot of women in those careers now.
