Facebook gets it. The future of Facebook is not the social network. They broke Messenger out of the core product and now it has 900M users. They doubled down and bought WhatsApp for 20B, and it now has 1B users. The company they could not buy, Snapchat, is the #1 app on the AppStore and arguably their greatest threat. Their enterprise counterpart, Slack, is the fastest growing enterprise app in history, with 3M daily users and a 4B valuation in 24 months.
