What's described in this article is some kind of automated postcard production: when you're at a tourists' attraction, just press a button on your phone and it produces an image of the location (with or without an insert of your face) based on a library of images. But that's not really "photography" (it's to photography what miniature plastic Eiffel towers are to architecture). A much more interesting and much more futuristic approach would be a device capable of recording a whole scene without a conventional sensor and lens; something that would record photons not because it's hit by them, but because it knows where they are. So this device would record all the light waves's position in a scene, at a given instant (the instant the image is taken), and then it would let you later reconstruct / produce any image from any position in the scene, with any kind of focus or bokeh, or whatever. It would also let you walk into the scene like in a real "mannequin challenge", etc.
