"women seem to be less underrepresented among CS folks in cultures where STEM professions are not historically low-status."

The correlation isn't so clear. STEM is even more unpopular among Japanese and Korean women than English-speaking nation women.

But thanks for pointing out that CS is hardly a desirable route to a good and comfortable life unless you love it for its own sake. It requires the same level of skills and ability necessary for a much more profitable and less difficult career in medicine, law, accountancy, dentistry, business administration, public administration, or the like.
