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…
Yeah, product teams can/should care about being responsible, but there’s an obvious conflict of interest.
To me, this story means Facebook dgaf about being responsible (big surprise).
