I've heard it was illegal for Google to keep him on. Here's what I've found online:

> Explicit protections against ... sexually hostile work environments, ... discrimination against unlawful sex stereotypes

From https://www.workplacefairness.org/sexual-gender-discriminati....

I would love to see a response from a lawyer. My understanding as a layperson is:

1. He is saying that biological differences explain why fewer women go into tech. That is not true, here is the best point-by-point analysis I've seen on it: https://www.quora.com/What-do-scientists-think-about-the-bio...

2. If you are a manager, and you ignore this analysis and agree that there is a biological difference, you can use that to explain why you aren't hiring/promoting women: it's not you, it's biology!
