In the extreme, the logical extension of this kind of application is that over time every surface could be turned into a lens-less camera, by applying a thin photon detector film to it and using AI computation to transform low-quality photon sensor data into photos for human or machine consumption. It could very well be that in the future, any wall, glass pane, or other surface could be cheaply configured to watch/record its surroundings.
