We absolutely do not need AR and VR in order to build the Metaverse. And I, 30 years ago when I wrote the book, I had a different view of it. And so I assumed that it would be all about goggles. But a lot has changed since then, and we've all learned a lot. So Doom came out the year after Snowcrash was published. And it's kind of almost hard to remember a time when there weren't games like Doom. Meaning games where your screen is a flat window into a three-dimensional world.
