It never made any organizational sense for me to have a "responsible AI team" in the first place. Every team doing AI work should be responsible and should think about the ethical (and legal at a bare minimum baseline) dimension of what they are doing. Having that concentrated in a single team means that team becomes a bottleneck where they have to vet all AI work everyone else does for responsibility and/or everyone…
I heard about one specific ratchet effect directly from an AI researcher. The ethics/risk oriented people get in direct internal conflict with the charge-forward people because one wants to slow down and the other wants to speed up. The charge-ahead people almost always win because it’s easier to get measurable outcomes for organization goals when one is not worrying about ethical concerns. (As my charge-ahead AI acquaintance put it, AI safety people don’t get anything done.)
If you want something like ethics or responsibility or safety to be considered, it’s essential to split it out into its own team and give that team priorities aligned with that mission.
Internally I expect that Meta is very much reducing responsible AI to a lip service bullet point at the bottom of a slide full of organizational goals, and otherwise not doing anything about it.
