The final piece of the puzzle fell into place on Tuesday. A lot of what it will take to make VR great is well understood at this point, so it's engineering, not research; hard engineering, to be sure, but clearly within reach. For example, there are half a dozen things that could be done to display panels that would make them better for VR, none of them pie in the sky. However, it's expensive engineering. And, of course, there's also a huge amount of research to do once we reach the limits of current technology, and that's not only expensive, it also requires time and patience – fully tapping the potential of VR will take decades. That's why I've written before that VR wouldn't become truly great until some company stepped up and invested the considerable capital to build the right hardware – and that it wouldn't be clear that it made sense to spend that capital until VR was truly great. I was afraid that that Catch-22 would cause VR to fail to achieve liftoff.

That worry is now gone. Facebook's acquisition of Oculus means that VR is going to happen in all its glory. The resources and long-term commitment that Facebook brings gives Oculus the runway it needs to solve the hard problems of VR – and some of them are hard indeed. I now fully expect to spend the rest of my career pushing VR as far ahead as I can.

It's great to be working with John again after all these years, and with that comes a sense of deja vu. It feels like it did when I went to Id, but on steroids – this time we're working on technology that will change not just computer gaming, but potentially how all of us interact with computers, information, and each other every day. I think it's going to be the biggest game-changer I've ever seen – and I've seen quite a lot over the last 57 years.
