For a writer, if you write out a plot, you can get the AI to actually simulate the character's responses and dialogue (even voiced by AI!). There, you've LITERALLY brought a character to life, each character is driven by a different persona simulated by a different AI, the quality of stories that will create, will annihilate what came before.
You want to write an adventure, but want to keep it unpredictable. Ask the AI for ideas, there, the adventure is now a true adventure, not a fake mirage created by the writer.
No need to describe scenery, no need to describe character appearances. Feed those descriptions into txt2img, and you get portraits that would have cost $1000/pic from top tier artists.
Generic and formulaicness, comes from having TOO MANY PEOPLE. Too many people involved in production, means the creator must dilute intent, appeal to wider audiences, and limit risks, to ensure costs are reclaimed. Once AI gets going, you'll see indie creators making full anime series, and releasing them on youtube. Because for an individual creator, even ad + patreon revenue alone would be able to sustain a comfortable existence, with no dependency on corporate or teams.
I thought people who love art, would be exhilarated by AI. I realized, the majority of artists don't love art. They love drawing, but not art. They love socializing with artists, but not art. They love receiving attention and income from their art, but not art. That's all fair and fine. But there will be people, who just want to create the best possible art, no matter the method, no matter the reward, and with AI, this latter group will outcompete the first, hard.
