I would probably guess that implanted cameras would be the next thing, recording maybe though optics implanted in eyes, or on contact lenses. And advanced computer recognition of visual objects.

Could let you run a search on where you last put something, and have the computing power to quickly search and jog back that last image of said object and thus last seen location. Image acquisition and recording would be as effortless and to look at a scene, hands free or maybe with a monocular or a pair of binoculars. etc etc.

But Analog will still be around, thats for sure. It may be difficult to find suppliers or consistent sources (for films and papers), or it may be regulated into small batch production by independents or garage chemists, but rest assured there always will be people who desire to use this beautiful medium.
