Have they done any monetization on WhatsApp yet? Which is ~2 billion users. They could literally add a few billion in revenue by showing a single text ad once per day or similar. That's not counting the fact that instagram is still basically in hyper-growth mode globally and facebook (the webpage/app) is still growing in every market except the US. Agree that (very) long term they'll need the VR/AR market to take off and capture a significant portion of that to stay on top of the digital ad business along with Google.
