Later today, Facebook will kick off its annual F8 developers' conference in Silicon Valley. As usual, CEO Mark Zuckerberg, along with a parade of executives, will unveil a slew of new products and features—some more significant than others.

Why it matters: Since the first F8 conference 10 years ago, Facebook has used the event to push its service forward. In 2007, it announced the Facebook Platform, and last year Zuckerberg presented the company's plans for the next 10 years. Zuckerberg is also likely to take the opportunity to comment on the company's recent challenges regarding "fake news," violent Facebook Live videos, and even an update on his U.S. tour.

The rumors:

  • A tool for adding Snapchat-style "Stories" everywhere: With a touch of javascript, anyone can add this hip feature to their app, just as Instagram, Messenger, and Facebook have! (We're kidding, but this tool, called "Zuck.js," is pretty rad.)
  • Bots for group chats: A new set of these "chat bots" that live inside Facebook Messenger group conversations and provide various info and service, according to TechCrunch. For example, one could keep a group of football fans informed on the latest game scores. This could address some of the clunkiness of the chat bots Facebook unveiled at last year's conference.
  • Instagram offline: Instagram is likely working on ways for users, especially in emerging markets, to access the photo-sharing app even if they're not online, according to clues in the event schedule.
  • Camera Effects Platform: Facebook will likely introduce the ability for outsiders to design and submit filters, lenses, and other camera effects, also according to the schedule.
  • Places Graph: A revamped and more powerful set of tools for using Facebook's location data could debut at F8, once again based on the schedule. Facebook originally rolled out its Places application program interface in 2010.
  • Secret hardware: Led by former DARPA director and Google exec Regina Dugan, Facebook's secretive Building 8 unit will likely unveil some of the gadgets it's been working on, according to Business Insider.
  • More augmented reality: A big theme this year will be augmented reality. And while the pair of glasses (or contact lenses) Facebook is reportedly working on probably won't show up at the event, related technologies like camera filters will begin to lay down the groundwork, according to USA Today.
  • Virtual reality: Last year, Facebook introduced its own 360-video camera rig, and demo'd its take on social interaction in virtual reality—so expect more VR this year. Facebook may also showcase its newest headset, according to Variety.

U.S. lawmakers are demanding answers from the World Bank about its continued operation of a $50 million loan program in Xinjiang, following Axios reporting on the loans.

Why it matters: The Chinese government is currently waging a campaign of cultural and demographic genocide against ethnic minorities in Xinjiang, in northwest China. The lawmakers contend that the recipients of the loans may be complicit in that repression.

Former President Barack Obama tweeted Friday that everyday Americans could become "collateral damage" if President Trump continues to attempt to slash funding for the U.S. Postal Service as part of his campaign against mail-in voting.

Why it matters: Trump linked his baseless claims that increased mail-in voting will lead to widespread voter fraud on Thursday to the current impasse in coronavirus stimulus negotiations.

Tesla CEO Elon Musk, who has spent more than a decade trying to disrupt the traditional auto industry, is sounding more and more like the man most closely associated with it: Henry Ford.

Why it matters: In his quest to build affordable electric cars for the masses, Musk is starting to embrace many of the ideas pioneered by Ford's founder — things like vertical supply chains and an obsession with manufacturing efficiency. A century ago that approach helped to popularize the American automobile by lowering the cost of the Model T.
