Why do we have to have equal representation in every single area?
We don't. But women were software pioneers and there were lots of them working in the field for awhile, and now there are not.
"What happened to change that" is an interesting question, to me.
How much do CS and engineers make? Their salaries generally look a lot more attractive first few years out of school and then they plateau after few years, whereas other careers, IB, consulting, management, law, medicine, etc salaries can grow quite a bit.
