So the young woman gets to university/college and wonders, "What sort of field should I study?" She picks up some newspapers or looks at some financial reports and realizes all the major high tech companies have MALE CEO's and decides the field isn't for her?

As I recall when I was there, everyone was thinking about (in this order):

a) What sort of stuff do I find interesting?

b) What sort of job might I get when I'm finished my studies?

I don't think it has changed all that much. 

Too bad ridiculous opinions such as yours have come to dominate the discussion.
