as an avp hobby dev i dont disagree with your prediction. its a product i want and think is good, but im sure most people dont want and think is bad.
i somewhat agree with your solution looking for a problem statement but i think a potential application for spatial computing is data collection and presentation. think of how many businesses depend on filling out forms to report on the state of a physical object/equipment. a spatial component where that form now has a location in space and the scene with the object can be reconstructed for review is valuable for businesses. to clarify, this is a case for spatial computing, not the avp. the avp is nowhere near rugged enough to do the job safely and one day the data collection is best handled by drones
