Mark Zuckerberg said in earnings last week that it was going to be a long time before they did contribute in a meaningful way to the business's profit. So is there some agreed upon or back channel on what will be the tipping point in terms of adoption, killer app, etc.? Yeah, I think it's a great question and I've been doing more reporting around AR and VR, but by no means an expert. But we're definitely seeing an upward trajectory from those figures at the same time,. It still remains pretty nascent and I do wonder what will be that deal breaker for users.
