I'll try one more avenue.
Everyone can see the obvious difference between a Rembrandt painting and a Pollock painting. Both are prized and both worth millions, but both represent vastly different "art movements." How did painting go from Rembrandt to Pollock? Why? Painting is painting, right? The only important thing is the picture, right? Wrong.
Art movements evolve as social consciousness changes, as politics changes, as information changes, as world events change. An art movement is not some fellows/gals saying, "Let's change the dictionary meaning of painting." Nor, is it those folks saying, "You over there shall not be called an artist or painter." That kind of silliness, and superficiality is not what makes art movements. Staying with painting for a moment, the artists evolved their consciousness to accept new ideas about Mankind, God, Liberty, Expression, Values, Morals and countless other human concerns. Whatever the "NEW MOVEMENT" was, it was not about dictionaries and quotations and some language bits, it was about changing the world, changing society, changing the course of humanity. It was about rejection of the status quo, or rejection of new ways of life, like industrialization or war or other tyrannies.
Photography. I am not arguing about dictionary entries, or names people call themselves, or chemicals or sensors, or images they are making - PER SE. I am arguing that for several years a set of conditions have been creeping into the wide photography world and the world at large in ways that are connected, and that I see as dangerous. I'll simplify the description of those changes as simply "creeping artificial intelligence and mass automation." Further, I'll add that I believe it is a danger to humanity's future. So, that's my position. Now, what have I been promoting with regard to that position? First a recognition that AI isn't some future dream, it's here now already destroying human creativity, and we should reject it at every level possible. Second to DISCERN authentic human creativity from AI garbage, and find ways to support authentic human creativity in all art forms. I don't want to read poetry written by AI. I don't want AI to write all the new novels (this is already happening). I don't want society DRIVEN by AI anymore than the modernist painters wanted a world drive by war once they saw the human carnage of WWI.
I'd like the art of photography to slide on past the grip of AI, and regain authenticity. That is a political goal, not a semantic argument. It is an economic goal, not a definition of what is allowed or what names people call each other.
