Depends on your end stage expectations for vr. If it's simply PS5 realism in a vr helmet, then you'll get that in Zuck's metaverse time horizon, 3-15 years. I ultimately expect the vr will be a letdown because of the interface, there is nothing on the likely tech roadmap that will make vr interface with the human body as good as fiction. You will need something from an alternate tech tree derived from some future white swan event.
