I would argue that trying to force VR on consumers by over-promising it before it has a 'killer-app' is harmful to VR as a technology, and I think that VR is a potentially very important technology. However I can't argue against the Zuck giving Carmack 20 billion dollars to build awesome and affordable toys that I love using, especially when it has the potential to scare off his stockholders and make him even more of a laughing stock. I say it is a wash.
