ADAM MOSSERI (HEAD OF INSTAGRAM): But the truth is, you might agree with me, you might not agree with me, that's fine either way, but there's no putting the genie back in the bottle. This is like being concerned about cars, or being concerned about the TV. You're not going to uninvent these things. So I try to spend most of my time not having that debate when I can but rather trying to figure out, given where we are, given what exists, how do we do the best we can? How do we take our responsibility seriously? How do we identify not only the issues that exist today but the issues that might exist tomorrow. How do we -- how are we a force for good? I don't think it's good enough, for instance, for us to just remove hate speech and racism from our platform as much as possible. I think we should be a force to reduce racial inequality in the world.
