I love these "the world is not what I want it to be" diatribes. Photography is going to survive in spite of what the author thinks. Naturally, in the grand silver age of photography, it was full of mediocre work too--the the photo he posted is a great example of that mediocrity. The same mundane stuff was produced as it is today. In fact nothing has changed. Technology has just made it easier to make mediocre work and show it. Just as developments in film technology did the same. It fact, nothing fundamentally has changed.
Still, a great artist always blames the technology--isn't that how it goes.
