For context, you had a reporting chain of Jeff Dean -> Megan Kacholia -> Samy Bengio -> Timnit Gebru/Meg Mitchell.
Timnit and Meg have been fired. Samy appears to have been sidelined, despite everyone involved in the ethical work liking Samy and finding him willing to protect them.
My best Guess is that Marian Croak (a Black woman who is currently an Engineering VP in an unrelated area) will approximately replace Megan Kacholia with Megan focusing on other areas, except that "ethical AI" was only a part of Samy's purview, much less Megan's, and its unclear if Marian is stepping down from her former position, or if she's going to split her time between ethical AI and completely unrelated work.
So there are no direct leads of the ethics team currently. There's a VP in charge who has other significant responsibilities and relatively junior researchers (some of whom are very recent hires with limited experience), and no one in the middle. So any chance of mentorship is gone, and the system is quite clearly adversarial. Those researchers have lost their direct and skip level manager, with no clear replacement. Lovely.
