I think that this could be a medium, long term thing for them. If you look at what's happening inside that company right now,. zuckeberg is rearranging a lot of chest pieces. He just put nick klegg in charge of all policy. What wos frly as to ask he didn't have to think about it any more. That means zuckerberg is going to be working on product full time. They have to go so solve a really a difficult set of technical challenges around how do you build ahead set augmented reality glasses? So i really do think that that company will be an r and d mode for five years.
