But it’s also about how you get there. If you only expose kids to pictures of white male doctors you’re going to give them a bias which will shape their lives and by extension the society around them.
I think techno libertarian suggestions like these are dangerous because they assume there’s one “canonical” place to fix these issues and all other places can just reflect the status quo, without affecting it (which in my opinion is not possible).
It’s like the old saying “dress for the job you want, not the job you have”.
