I'm too far from it to know exactly how Facebook is spending the money. In my mental model they are spending it on "make VR work" and that's how I'm thinking about it here. This is why I hedged a little in my original comment and said that this is at least the kind of thing Facebook should be doing. I really hope they aren't spending all, or even most, of their money on the demos we are seeing. I don't necessarily think their specific strategy is right, but trying to do something is right. Personally, I'd be spending everything on brain-computer interfaces - because that's the only way I can see VR working. What would happen if you gave a team of scientists billions of dollars a year with the mandate to get a brain-computer interface for the highest level animal on which you could ethically and legally do unlimited experiments? Get that down, work your way up to a less intrusive device targeting apes and then humans, and then you could do real, serious VR.
