You raise some really good points about the future of photography. But as some people here have noted: there is the one percent of pics that iPhones cannot do (yet?).
I know with high speed and low light situations phones are simply not there.
Which comes to the future: just because everyone will have the same access to most kinds of visual documentation (photos) doesn’t make the cream of the crop any less valuable.
A similar situation has occurred with writing: it’s everywhere and everyone can do it, but there are certain styles that people pay for, certain stories (be it old school novels or newer forms of fake news on the threads of articles).
I should note that I never heard of the light camera you linked to. Sure it’s unconventional, but I would not dismiss such items as I think they will lead towards the future. Not that it is the future (lenses pointing many ways would help, and as with the 360 camera, it doesn’t seem to add to the idea of seeing as a human does)
Myself I’m experimenting with different ways of using the visual medium of photos to show more than a single frame can. This isn’t always successful, but I believe that now that the tools for camera obscura have grown so ubiquitous, finding new ways to remember and see will be important in the future.
