IMO, this also means that there never was a big discrimination or opportunity problem after hiring (in promotions et al). They fixed the hiring pipeline and solved the supply-side bottleneck leading to more female representation in leadership.
Makes me wonder if solving this at an even more grassroots level will lead to even better results ie. ensuring more women are a part of the working economy and more women are educated.
