This is a really great talk about the possible future of VR. I just purchased an HTC Vive. I went with the Vive because it offered the most interaction and the most open platform. The Oculus Rift is owned by Facebook so that does not look like a great company to get behind for open software and the PlayStation VR is on a closed console. We have a long road ahead with better hardware and improved software to make the VR experience more meaningful in new ways.
