I would say that I think one of the things that Aaron and I have discussed and focused some attention on—I offer this as a partial answer—is that the universe of social media communications is increasingly being affected by automated bots. These are simply machines out there that amplify, according to certain algorithms, certain kinds of messages, and they can be used for disinformation purposes by foreign state actors. We saw this with Russia in the 2016 election campaign against the United States. They can be used by social media companies to boost ratings.
I think the conclusion we've come to—without having the tools and necessarily suggesting how you do this—is that we have to tackle the automated bots issue in some form or another, to reduce their impact and the scale of the use that is made of them.
