Do you believe this is a viable trend? This debacle seems to point to the death of 'Ethics research' inside of corporations. What do companies stand to gain from hiring ethics researchers who are a liability to the shareholders? My guess is that the model will go back to using CSR budget to invest in 'social good' non-profits and think tanks that stay at a safe distance while still mentioning you as a 'Platinum Sponsor' and bringing you in for fireside chats.
(this is not me advocating against ethics research, or against bringing ethics into AI research; I'm just trying to be as cynically realist as possible)
