He literately can't say anything of substance on a topic like this or else his words will show up all over the news as an attack by YC on some party or other.

i teach 8 year-old girls how to code in my free time and one of the biggest challenges to their success is re-wiring them to believe in themselves, in their critical-thinking skills, in their ability to solve problems. it seems they don't need a few mentor-role models: they need a chorus of people encouraging them and reminding them of their innate abilities. which leads me to believe—i can only extrapolate—that this must be what many boys (and men) experience on a quotidien basis.
i will never know, but i can help create that for myself and other women, particularly the wee ones. :>
