As a hobbyist, I am not pessimistic. AI is just a tool like agriculture (more persons/acre) or the internet (more dross/person). Hobby/arty photography is an art form (though not when I do it) and art forms are free of the efficiency requirement that AI serves. After all, there are still classical guitars after the moog or the stratocaster, photographs (even film) have survived the transition to motion digital, and there are still painters out there. Low volume, high quality, and personally rewarding activities are minimally affected by technology upheavals. Commercial production, in contrast, must adapt to the new technology. That is not necessarily a bad thing, but change is hard.
Painting is a good analogy. Cheap portraiture used to be a profession, but no one does it any more. Portraiture was overtaken by photography and became something else. In most cases the photos are still cheap portraiture, but they use an entirely different skill set. The work flow is much quicker and easier. Similarly, AI will pose a challenge to commercial catalogue work, run 'n gun weddings, cliche landscapes, and other high volume items. Anything that needs to be done quickly, is rule based, and uses cash as a definition of success will require content creators to adapt (use AI) or die. The good news is that the new AI/photography would generate cash for the skilled practitioner who does adapt. Commercial photographers are not doomed to starve, just to change. I think they are very aware of that.
In contrast, the sort of hobby photography that many of us do has no need for AI because it doesn't need to be efficient and profitable. We could describe its purpose (and that of art in general) in terms of evolutionary biology but that would probably offend many of us. Instead, let's just say that some humans use artistic activities to discriminate themselves from the herd, just as others use wealth for the same purpose. Artistic success is not defined by income, but by personal commitment (I will do this), feelings of accomplishment (I am good at doing this), and public acclaim (OMG, you sure are good at doing this). That is how art rewards creators, and that is why it will continue to motivate some photographers - however inefficient it is. In rare cases it can also make money, but that's not why we do it. Therefore, hobbyists and artists are pretty safe from AI - if they want to be.
Because it serves a basic human need, art will find a way. In fact, it will subvert AI to create a genre of AI artists. Their product will be new material, not a different type of photography, but it will occupy some of the same market niches. Therefore, for the commercial pros things are a bit dire because AI can provide alternative work flows. It will be harder to put your kids through college by producing photos but, not to worry. AI will provide new tools that pro shooters can learn and profit from.
