Women in gaming (or just tech) is an issue that no one can answer properly and everyone has issues with.
Yes, more and more women are getting into tech.
Yes, it's a boy's club. What big business in North America isn't full of rich old white guys and all the jackassery that comes with the mindset of people living in a world that isn't the real world?
Yes, there is less discrimination now, but it exists.
Yes, there should be a lot more women in tech these days - and we damn well tried. But a lot of us got shot down and we gave up. Some didn't and they are now doing what they love. The majority of the men they work with are fine with it. Some aren't.
Discrimination exists, people. Want an example of why women my age (30) aren't in tech much? Keep in mind this is the late 90's, early 00's in Canada in a capital, progressive city.
In Junior High girls were still expected to take cooking and sewing classes, while the boys took woodworking and a mini engineering class. My mother literally had to go down to the school and have a screaming match with the WOMAN principal because they refused to let my sister take the engineering course. In High School I signed up for a computer science course, alongside my sister. We were the only girls in the class. The teacher helped everyone in the class but us. When time for the end of term project came around, I fumbled my way through, abut got stuck on some code (It was if/then basic stuff - make a little game where you hit a button and players run around a baseball field). I called the teacher over, he sat down, looked at is, and said (I quote, because I remember the moment clearly) "Well, you're screwed." and got up and walked away.
My cousin also founded a VGX company. He hired people in and trained them without any experience - including my cousin who was the same age. We asked him over and over again if he could take us on as well, but he always refused. Even as he got bigger and bigger in the city the only women worked PR and reception.
Sexism is still rampant. It's getting better, but for someone my age, we grew up still being told to conform to traditional gender roles. Teachers and people of influence were sexist. We got beaten down a lot.
Some people fought back and got into tech. I'm put to shame by them because I stopped fighting. I went back to school in my 20's and now have a lot of tech education, but it's not programming.
It happened. It's still happening, but not nearly as much.
However, when I was teaching (only a couple years ago), sometimes girls were encouraged to go into tech... but if one of them said video games, they were talked down to. Told to go into the big techs, like engineering or biotech or that kind of thing. It made me really angry. I actually got in trouble from admin for telling girls to go into trades and programming and such instead of going to university for traditional degrees.
The world is still kind of backwards. It knows it's backwards now, and it's changing, but it's going to take time and it's going to take hard work from everyone. It's just still not fair that women have to work harder. But that ill change too.
We didn't get to wear pants in a day, and everyone else has had much more to overcome, but it will all come with time and hard work and acceptance.
