Women as a whole aren't born being more inclined to go into non-CS fields. This preference is acquired at some point in childhood. I am comfortable making this claim because we know that in the mid 80s 37% of CS graduates were women vs. 12% today. Something happened in the meantime.

I don't think it is a result of supposed wage gaps (which supposedly exist in all fields) or supposed widespread sexism (as if other fields are any better). But I do think it is a problem. We have a shortage of good developers in this country and not being able to draw talent very well from roughly half the population is not helping.
