What is the connection between AI (or rather neural networks) being able to generate photorealistic images and your own photography? If I sit in the woods for a couple hours waiting to get a nice shot of a bird or other animal, go home empty handed multiple times, all that makes the final picture all the more rewarding. I can print it, hang it on my wall and be reminded that I managed to get that picture. Same with most other things most amateur shoot. Portrait, nude art, street, landscape etc. It's about you getting the shot you want.
Unless you make your income from stock photography I do not think professionals have to worry too much either. No one is gonna "AI" their wedding, or the shots of the new product. Wildlife and landscape is also strongly bound to reality.
All in all it seems it won't affect most ppls photography much, especially not amateur photography which is about the enjoyment of it, not about the question if this could be generated by a neural network (probably a pro could take a better shot than you as well, does that stop you?)
