As someone who's in engineering, i can (to no surprise) confirm the imbalance of men vs women in the field. But this imbalance makes at least some sense to me - There's now a lot of programs here (Denmark) to get girls more into tech, and to make sure that those who are already studying it keep doing it. Girl code camps, study groups, what not. That's some really good stuff and it's helping things in the right direction, slowly.
I see no reason why there should be an imbalance in something as gender-less as coffee. Everyone loves things that taste great. But we also see it to some degree in the culinary world, right? We all know stunningly talented female baristas and female chefs, but we just know more that are male - And with a larger male player base, there's a bigger chance that the authorities in the industry are male even though they might as well be female. Sexism is a factor but it is hardly the explanation.
Sometimes it's difficult to see where your current road is taking you when you're deeply involved in something that's caught your interest. Suddenly you're on top of the world. How'd you get there? Who knows. Studies show that men are more likely to take risks, and if you're going to be an industry leader you've probably taken a good deal of risks. Factor in the generally larger base of men and here we are again.
But who really knows? It's such an interesting topic that we need to get to the bottom of. I have no idea how to solve it; I think noone has. What i'd like to do is sit every person in the world down in a big circle and we'll all have a chat about what the hell is going on
