If anyone, man or woman, decides to pursuit a given career because they can see others like them in the field, then really, I am grateful they don't. I want to work with people who deeply care about their choices. Who are dreamers. Who are willing to give a lot to fulfill their drive for knowledge. Who learns out of sheer curiosity of the world around them. Who can ask a meaningful questions. Who believe in what they do. Not with a sheep who chooses to follow other sheep.
If people want diversity at work, they should start with elementary school first. Do not assume any biological equality or lack of it up front but also do not ENFORCE any. Just give people equal rights to study and to make their own choices.
