My personal 2c is that it is a lot about perception and awareness. You need to be aware a certain thing exists and how it works before you can aspire to do it. I'm sure you've met people in the past that had jobs you didn't even know existed. And invariably since some populations have been less present in tech, less of that population will be exposed to it, and thus aspire to work in it.

Sometimes the smallest influences can have a big impact, both positively and negatively.
