Sharon Drexler: This seems like a good step or maybe a sign that as a community, we're sort of taking those controversies and learning from them in some interesting ways. I certainly haven't seen this sort of idea of about a user agreement. There's been user agreements that sort of said that this is meant for academia and not industry,. But this seems like it goes beyond that. And they actually have a deep fake detection challenge, collaboration with other industry leaders. So the idea here is that Facebook AI with this data set is aiming to catalyze that in particular.
