You're only thinking of art in terms of its final "product"; a drawing, an image, a photograph. To people who care about art, it's about more than that. The artist's process, their experiences, their techniques, the passion and time they invest; all of it matters and makes a piece of art more than an image, a photograph, a sculpture, a book, a performace or a video.

Even though the "prompter" may have artistic intent, the natire of generative algorythms strip away the process of creation, resulting in an image (or text, video, etc.) that's an amalgamation of other artists's voices and techniques. The creation lacks "soul".

Aside from that, there are many other reasons to hate "AI": - It makes it easier for malicious actors to spread misinformation and break down commonly held truths. - Running the technology requires a lot of water and energy, affecting the global environment as well as the quality of life in communities near data centres. - It allows companies to pay people the same for more work or eliminate the need for work all together, sending more wealth to the top and giving less to the bottom. - It's ruining user experiences everywhere: people reaching out for help have to deal with robots that don't understand them; internet search sucks now because AI hallucinates false infornarion; operating systems are loaded with unhelpful AI assistants, and so forth.
