An odd take: While I admire Margaret Hamilton, it has less to do with her undoubted technical chops, and more to do with her willingness to be a symbol, an icon, a photograph, a meme.
When I came to the geek trade in 1980, there were *lots* of women. The first two hardcore systems programmers I ever met were women.
I didn't need Hamilton to look up to, I already had two serious geek women to learn from.
That changed. There are many fewer women in the trade today than there were back then.

Today I look at an organization's diversity as an indicator of its health. I look for balance of genders, across ages, etc. Some have it, but many don't. I'm sure there are many reasons, but I think it may boil down to women having less tolerance for bad environments.
Also, I took a college class in programming from a professor who happened to be a woman. Through her passion for teaching it, I graduated with computer science as a second major.
