I do think there is a use case in work - I can imagine sitting down and doing CAD in a 'real 3D' environment once the resolution and responsiveness are high enough (probably still with a keyboard and mouse).
One thing that VR gives you that a monitor doesn’t is 1:1 scale. It’s so easy to get that wrong when working on a scaled down version of the model. Though you can just place people in your scene for reference.
