Creating a purely functional VR experience may not be tough, but a user-friendly and cost-effective experience hasn't been feasible until very recently. Grasping at straws isn't a good strategy. Facebook's desperate attempts to catch up in mobile are a resulted of their short-sightedness. They didn't anticipate the rise in smartphones and the changing consumer landscape. The idea behind this acquisition is to not only avoid missing the boat again, but actually drive the boat into the future. I feel like you are mistaking where Facebook currently is with where it wants to be. Facebook, at its core, wants to be a social hub where people connect and come together. I think your vision of VR as a gaming-only platform is extremely short-sighted. There are dozens of other applications that I can easily see completely shifting the way we interact and operate online. Why Skype for a business meeting when you can sit in a virtual board room? Why go all the way to a doctor's office if you can communicate face-to-face and have all of your vitals tracked through a bracelet? This is something we agree on, but I I think it is crazy to assume that because they bought Oculus, they are abandoning their main (and most profitable) value prop.VR ain't tough. Two screens headphones motion tracking = VR. Everything else is optimization.
Grasping at straws, however, does not a strategy make.
Know why people use Facebook? Because all their friends forced them to.
Figuring out a way to turn Facebook into a desirable location instead of an obligation is exactly what Facebook should be doing.
