There aren't a lot of jobs that can really use the 'space' provided by VR. I think the adoption here would have to drastically outpace multiple monitors and OS workspaces and keyboard shortcuts. I can easily get to 10-20 tabs in VS Code or a browser, but my attention is only really ever on one at a time. If I have to search through them, I'll have to do that on a monitor or in VR. I might be able to organize better in 3D: HTML files on the left, CSS files on the right, JS in the middle, backend reference above, tools and console below (like 5 monitors in a plus pattern).
I'd need probably a dozen or so channels of information that I had to cycle between quickly to convince me, given I've gotten used to multi-monitors, workspaces, and keyboard shortcuts. Maybe some futuristic high level analyst job that needs to look through lots of different kinds of information (geographical, text, videos, etc) at once.
