I wonder how the wide-scale move to work-from-home will change this. Having more flexible work environments while also making caregiving more possible (because, let's be honest, women still do the vast majority of caregiving, even if they work full-time) AND not spending as much time in a physical office reduces the exposure to these "traditionally male cultures" might make software development more attractive to women.

Just some random thoughts, it will be a long time before we know the effect.
