Being able to predict the gender of a brain with a 69-77% accuracy does not impress me at all. That's certainly not enough to make sweeping broad generalizations about an entire gender. This whole discussion is just silly. In fact, in the memo, he states "I’m also not saying that we should restrict people to certain gender roles; I’m advocating for quite the opposite: treat people as individuals, not as just another member of their group (tribalism)." It seems like a blatant contradiction to so many of his prior statements, but  put simply, it's just a privileged white male whining that Google puts resources towards uplifting under-represented groups that he feels aren't deserving. Gross.
