I'm not sure how you can merge the two theories that "Women are just better at people skills" and "Women aren't better than the best". The whole thesis is claiming that women are as naturally superior at people skills as men are naturally good at tech/STEM. Google is supposed to hire the best, and it's >50% men, so why isn't something that "hires the best" (in politics) still <20% women (e.g. US Congress).
