Facebook’s social VR manager, Michael Booth (who is in the VR video above with Zuckerberg), recently posted a photo from last year’s demonstration, adding that he’s looking forward to this year’s conference.

Zuckerberg has said in the past that he believes in the future, people will wear VR headsets in public (presumably without shame), and that it may take over a decade to realize the medium’s potential. Zuckerberg seems to understand that even with impressive hardware like the Oculus Rift, nothing will matter to consumers until there’s something actually worth spending a lot of time doing in virtual reality. The average Facebook user spends nearly an hour with the social network every day, but convincing them to strap on an expensive headset (and potentially fight off motion sickness) to do the same in VR is a much bigger ask. Hopefully, for Facebook, the sessions at this year’s developer conference will help developers start to answer that question.
