However, this is a case where the game devs are lacking in vision.
(1) My very first impression of the news last week was: Wow, I did not know that Zuckerberg had the guts and vision. I did not respect Zuckerberg at all. After the news, I see it as not only a big move for Facebook, I also explicitly acknowledge Zuckerberg as a visionary. Where this can go will disrupt what we think of as social networking, and being able to throw away the work which you have a vested interest in in order to bring in something greater, that takes courage.
(2) Discussing this with friends and then looking at what is emerging, it is pretty clear to me that this is not a vanity buy, and that the scope of Oculus has now been expanded to something much much greater than gaming. We're no longer talking about the next evolutionary stage of gaming; we're talking about the next fundamental shift in how the mainstream will interact on the internet. Gamers have this unconscious, perhaps implicit, understanding of what it means to interact with the virtual world; many folks in the mainstream do not. When this pans out in the mainstream (months? years?), it will create a shift in the psychology of individuals, something we have only seen discussed in sci-fi and cyberpunk stories. Or at least, that is the potential. Execution remains to be seen :-)
(3) Game devs in general have great imagination. Like artists, filmmakers, game devs bring their vision out into the world for others to experience. They tend to have a better feel for the future, for what the world can be, than your average person. However, I find it ironic that the game devs are so fixated on Oculus Rift = Gaming Device, that this is one of the rare times game devs failed to see the greater vision.
(4) Based on what Caramack, Palmer, and Abrash were talking about in the articles that have emerged ... until Zuckerberg showed up, they too also framed the Oculus tech as a gaming technology. That was what they sold it as in the Kickstarter, and many people were on board with it. So I understand how many gamers and game devs are up in arms about this. It's also kind of sad to me: these same folks who are so imaginative are failing to see the much grander vision.
