I agree. I am sure it would be pretty helpfull for models in the background though, which dont need to be perfect, just an approximation is usually enough. At the least its gonna look better than a billboarded image

If the application is gaming, I feel that if a prop is far enough away that this quality of model is acceptable, then you're better off just using a flat texture for efficiency. These generated 3D models aren't necessarily low-poly, despite being somewhat janky.

While I can't personally see much application for this in its current form, the technology is really impressive nonetheless. I'm very interested in seeing how far this can go.

It seems sort of unnecessary to do it from a single image. Just get a little motion of the camera (just a second) and you can get way better estimates for depth.
