(edit to give some body to my comment above:
Hosting a great dinner party is hard work and requires coordination between food, decor, seasonality, people attending, etc. It is akin to a director coordinating the parts of a film. So I do think hosting a good dinner party can count as artistic expression.
I don't know the parent comment's intended reading, but I was reacting to the idea that typing a Sora prompt makes someone a good artist. If the parent means instead that AI allows people to coordinate multiple media in a broader expression that was not possible otherwise, then I fully agree.
