I agree. VR will have killer apps in particular domains, but that doesn’t mean it will be used by everyone all of the time. For example, I work in ocean mapping where we have large amounts of point cloud data that need occasional manual editing/QAQC in an environment that matches the dimensionality of the data. My colleagues are working on some very interesting VR point cloud editing tools [1].
AI doesn't need to replace doctors for it to be useful.
Crypto doesn't need to replace your credit card for it to be useful.
If none of these things are useful to you, that's fine, other people find them useful and that's okay.
Think "and" instead of "or".
