We probably won't. GS is a reconstructive method, so when data is unavailable, you can only perform poor interpolation. You would need additional generative, not reconstructive, models. However, this would open the door to unfaithful augmentation again.
Different applications.
GIS won't want generative hallucinations.
Consumer mapping apps, social applications, and games (eg. flight sims) will want the maps to look as good as possible.
