Based on what? They don't end up there, but we have evidence (based on decreasing enrollment in degrees) that they USED to be "more interested" (If you use that as criteria). Do you think they generationally are just more aware of what it really is now?
How would that happen without ALSO becoming more aware of the absolute vile GamerGate-type shit women have to face, from the smallest "let me assume you don't know anything" to the "let's make rape jokes" to the "Can a woman have confidence she probably won't be groped"?
If you start with the premise that women "seem to not like CompSci", you've already assumed the problem and normalized a lot of factors that don't have to be normalized.
