Back in the day there were tons of people who were totally opposed to the rising genre of "electronic" music. Today you couldn't call electronic music "not music" without drawing the ire of lots of people.
In the same vein, people opposed the internet, digital drawing tablets, digital cameras.
AI is interesting because it can be use to "just prompt", and those outputs can't be called art. But actual artists are using the technology as just another tool to accomplish even bigger things:

Of course AI will still be used for slop and fan fiction, and people will endlessly try to fix Star Wars and Game of Thrones [1]. But that shouldn't be used to detract from the medium, because there will be an abundance of people doing amazing work that stands on its own legs.
