It's not new territory.
Plenty of prior art.
An obvious one is, "bring your TV / computer screen with you". A video of me watching TV, I turn my head, the TV turns out to be just a VR projection.
More fantastic, we need to be inspired by Sci-Fi. Holograms/holoprojections become possible with good-enough AR. The Expanse series is full of them.
Or some form of "structure projection" onto reality. Where does this road go? What's behind this building? Where is the patient's bone broken? What does the full puzzle look like?
Bottom line is, this is either a very amateur team, or a Theranos-level product.
Every new invention builds upon what came before it in some way, right? Like, perhaps when Daguerre was developing his earliest cameras, people wondered why we would want to capture pictures like that. I think not, though, because there was already analogs in the form of paintings and things.
This is completely new territory, and it feels a bit like a solution looking for a problem. There really isn’t a prior analog that I can think of! But maybe there is, and I just am missing it. But I could imagine it being transformational, if it is eventually found.
