"Pushed out" is an odd narrative for an industry that is bending over backwards to try and draw more women in. Is it even possible that women (on average) are less interested in tech work and thus have chosen (on aggregate) to pursue other careers instead? It seems like even asking that question is forbidden.
Why is the same level of angst not applied to education, where <20% of primary school teachers are male? Have the public schools been pushing men out, or are men just not interested? Or maybe it's some of both? Do we even know?
