I'm a biased observer, sure. But I feel very confident in saying that VR is never ever going away, let alone already dead like OP was saying, or even remotely comparable to 3D TV.

It's not (as it stands) going to be adopted as the media-platform of choice for consuming mass amounts of netflix and marvel movies, but there's way more niches to make it a viable go-to solution for many problems.

Most of our video is rendered down to ordinary video that gets reprojected, driven mostly by a requirement to be able to be played back on lowest-common-denominator hardware and platforms; nothing near as cool as what Carmack's article details. But there's other problems that require fun solutions to, too.
