I think there may very well be a few usecases of valuable improvement in life. I suspect those benefits will actually be in work like design and construction. The ability to see an accurate representation of the thing you are going to spend a half a million dollars on, in a realistic 3d space that you can walk around and interact with in with augmented reality, should provide valuable feedback to the design that improves the final product.

The ability to “see” the schematic of where the wiring is in your house as you plan or implement an additional outlet. Or where the cable was buried in the yard, etc. That stuff will be good.

But 95% of it is going to be dystopian dopamine treadmills and the decline of real satisfying human interaction.
