Cameras replaced only a very specific kind of painting, one that some people still do as a hobby (realism).
To your second edit, the fantasy of automated robots has always been to move us in the direction of a leisure-based society. Even today, Elon musk is promoting robots and AI as the means to get "universal high income".
The fact that this often does not pan out (though arguably laundry machines, factory clothing and vacuum cleaners have done more than almost anything else in that regard) does not mean that the idea is in any way uncommon.

That was by far the most common way for artists to provide for themselves though, cameras did take their jobs.
Similarly, text to image only solves a very specific part of art, art where you aren't very creative but instead draw an image based on a description. Artistry based on coming up with new things to draw will still be there. Sure most jobs artists do today are based on drawing based on descriptions, so its the same situation as with the cameras.
Those are the equivalent to prompt engineer artists, they use the new tool to create new art. Still removed most of the jobs, there isn't nearly as much need for photographers as there were need for painters.
