Generative ai is just a tool for creating text and images. Not everything created using is art, just like not every piece of text written by a human or an bunch of pixels drawn in photoshop is art. What matters is intention of the author, the effort put in and whether other people perceive it as art.

It silly to call everything created by ai as art, but not because of the tool used. Most of it is not art simply because it was not created for that purpose, it is there for pure silly entertainment.

It is equally silly to vehemently hate it if the creator does not even claim it's art.
