10:03 AM: "Privacy gives us the freedom to be ourselves. It's easier to feel like you belong when you're part of smaller communities amongst your closest friends," Zuckerberg says. "As the world gets bigger and more connected, we need that sense of intimacy more than ever."

10:04 AM: "The future is private," Zuckerberg declares. "I believe a private-social platform will be more important in our lives than our digital town squares." Whatever that means.

10:05 AM: Zuckerberg laughs. "I know we don't have the strongest reputation on privacy right now, to put it lightly. But we're committed to doing this well, and to starting a new chapter for our product. It's going to take time and it'll feel like we're unearthing old issues for awhile, but I think we've shown time and again as a company that we can grow and build products that people want, so I'm confident we can do this."

10:06 AM: Zuckerberg says there are six pillars to Facebook's new platform. While screenshotting this moment, Facebook asked me about how I feel about Facebook while watching this video.

10:08 AM: "Over the next few years, we're going to build more of our services around these ideas. This isn't about building features, we need to change a lot of ways we're running this company today," Zuckerberg says.

10:09 AM: "Right now we're going out and consulting with experts about getting this balance right and building privacy in up front," Zuckerberg says. "And we're working to make sure developers use our tools for good."

10:10 AM: "I believe that over time, this is going to make a more trustworthy platform that's better for everyone," Zuckerberg says. "We're developing infrastructure that knows how certain types of data are allowed to be used, so it can automatically block unauthorized access in our infrastructure, and prevent errors." (Again, notice the poll.)

10:12 AM: "It's not going to happen overnight, and we don't have all the answers on how this is going to work yet. But today we're ready to talk about what this privacy focus is going to look like across all of our apps," Zuckerberg says.

10:13: Zuckerberg talks about Messenger. "Our next goal is to make Messenger the fastest messaging app out there — to be the most reliable, though, we need to ensure the service is available everywhere you are, and that means having a great desktop experience. So we built a new desktop app so you can chat and video chat in a native app on both Mac and Windows. This was one of our top most-requested features."

10:15 AM: "We're going to enable two billion people to have their conversations privately, without worrying about hackers, governments, or even us worrying about what they're saying. I think this is going to be a historically important step," Zuckerberg says.

10:16 AM: The new Messenger will have a Friends tab, which has a bunch of private videos and messages that are not public. Only you can see them. You'll also be able to co-watch videos with your friends.

10:24 AM: The desktop version is coming later in the year. A lot of changes under the hood made this happen, to feel like groups are at the heart of the Facebook experience like friends and family are.

10:25 AM: "This is the biggest change we've made to the app and website over the last five years, and we're shipping this today," Zuckerberg says. "We're going to start rolling this out, everyone in the US will get this today."

10:26 AM: Zuckerberg moves onto Instagram. "One of the more interesting challenges with shopping is that we browse in public, but the interaction is private. We think there's an opportunity with Instagram to marry these two experiences and make them both better."

10:29 AM: Zuckerberg says the privacy focus extends to augmented and virtual reality as well. "Two years ago at F8, we talked about how the camera was going to be the first AR platform, and in the last year alone, more than a billion people have used AR features in Facebook apps. To make this into a broader platform we're making it easier to build for. So we're bringing the Spark AR studio to both Windows and Mac, and we're going to open our AR platform for Instagram so everyone can build for it."

10:31 AM: Zuckerberg announces Portal, its camera for the home, is rolling out internationally. And Facebook is adding WhatsApp to Portal, so all video calls are end-to-end encrypted.

Preorders open today, they both cost $399, and start shipping on May 21. Zuckerberg announces everyone in the crowd is getting a free Oculus Rift S, which results in a lot of cheering and some scattered "thank you's."

11:11 AM: Instagram also wants to address bullying more broadly. The company says it will take time to make this happen, but it's looking at safety tools like "Away Mode," where you can opt out of Instagram during sensitive periods of your life, like if you're moving or are getting over a break-up. Instagram may test some of these features soon, or never at all, but Mosseri wants people to know that Instagram cares about this issue deeply.
