Facebook has gotten us all to share text posts and photos, and is seeing a lot of use of video. Now, it wants to turn is all into live streamers, and use advanced technology to aid our use of our phone cameras: That’s the gist of an outlook that Facebook’s Chief Product Officer Chris Cox gave at the Wall Street Journal’s WSJ.D Live conference in Laguna Beach, Calif. Tuesday.

Cox said that Facebook has already seen 400 percent growth in live streaming since opening it up to all of its users in May. Not all of that is coming from users watching broadcasts of major media brands, he explained, adding that the number of small broadcasters — teenagers that stream to just a dozen of their friends — was a surprise even to Facebook itself.

Key to Facebook Live‘s future growth will be technology that adds to the live broadcast experience, said Cox. He showed off one example that Facebook is currently experimenting with in the lab: An app that automatically takes the camera input and in real-time renders it in the style of famous painters like van Gogh using neural networks.

The bigger idea behind experiments like this is to turn the camera into an advanced tool that unlocks live streaming and augmented reality experiences, said Cox. “This is going to help take the technology to the next level.”

Cox was joined on stage by Facebook’s Chief Operating Officer Sheryl Sandberg, who argued that Live is an evolution of free expression on Facebook, complete with the challenges that come with it. The company has been in hot waters in the past for overzealous removal of content, and suggested last week that it was ready to relax some of its guidelines for acceptable content.

“Facebook is a platform for all ideas,” Sandberg said. “We also want to be a really safe community. Those two things can come into conflict.”

As Facebook is making decision what content to keep on its platform and what to ban, it often finds itself confronted with criticism that it is exercising editorial control — a charge that Sandberg and Cox denied. “A media company is about the story that it tells,” said Cox. “A technology company is about the tools that it builds.”
