I'm a context guy, so in attempting to explain why it is so difficult, you have to look at the social context of tech, which isn't the most inviting place to begin with if you're not white, straight and a dude.

Combine this with economic inequality factors and it makes that much more difficult for non white people and women to even start building anything.

So you generally get white guys building platforms for ALL of us.

A culture that favors their perspectives.
