Timnit Gebru has a BSc, MSc and PhD in electrical engineering all from Stanford. She did actual electrical engineering work at Apple previously. Maybe it's hard to believe but she's not just another SJW.

The idea that companies only need to do maximize shareholder value isn't that old and was only popularized in the 80s. If you restrict creating value to that, then maybe she didn't create any at Google. But maybe Google wants to create a software that works equally well for everyone and raising the issue of IA biases would have helped achieve that goal.
