I agree with him that photography  is quasi dissapearing, but I very much disagree with what he thinks the reason for this is.
In my opinion it is not that Kodak closes, film dissapears and not even that every cellphone gets a camera. Perhaps the last one has an indirect influence.
The problem is that nothing new appears. Maybe it is a consequence that almost anything was photographed, but even this is not the real, exclusive reason. I think the reason is that no revolution is happening. Nobody comes up with something really "art-shaking". I see only thousands of variations of the same "streetphotography" that's considered "cool" but mostly saying nothing, industrial where the more trash the better and if you put a model in some dirty or motoroiled clothes in the picture than it is considered perfect (but unfortunately it was presented the same way thousands of times, maybe the first time it was somewhat innovative), social photography where the goal seem to be to find people in the most desolate environments, portraits, fashion all the same endless variations of what we have seen also thousands of times, etc, etc. Nothing really revolutionary nor in the ideea nor in the realisation. So at least photography is stagnating for a long time now. Without revolution it can't exist art, even evolution is not enough.
 I don't men technical photography, of course.
