Facebook F8 conference: What we learned during the opening keynote speeches

Facebook's F8 developer conference has only been going for a few hours, and already there's been some huge announcements. Gone are the days when F8 was just for announcing newsfeed redesigns - in the opening keynote speeches, we've heard about a brand new Messenger chatbot platform, a solar-powered WiFi plane, and all kinds of live video innovations. Here's some of the main things we learned at the F8 opening event. Zuckerberg straight away took a thinly-veiled swipe at the Republican presidential candidate while talking about Facebook's plan to'connect the world'. Speaking to the assembled crowd of developers, Zuckerberg said: "As I look around the world, I'm starting to see people and nations turning inwards, against the idea of a connected world and global community."
