I'm a game developer who used to work at studios of over 200+ men with no females.
It changes, really fast and it happens overnight.
The arguments back then were:
Women don't play videogames.
Women don't code.
Women don't draw.
Within 10 years some of the brightest and most talented developers are females. Several major studios are headed by women.
Last year's Game of the Year (Uncharted 4) was written by a woman, and several key positions were held by women.
I also teach part time (3D Character Art).
When I started teaching 7 years ago, it was all-boys. The arguments were "Boys grow up reading comics, and copying them at a young age, to develop technical skills.
Last semester there were more females than males, and they were really *** good. Turns out more and more women are enrolling in engineering, and programming as well.
I think hockey will get there eventually. If we give it time. Some bright talented women will break in, and it will change everything.
I still think some visibly minorities, and gays might make it there before, but it'll get there.
