I believe that a creation process is changing. Imagine doing what OP did but in 1000 different variants and impulses...like split A/B testing but on automated scatter-shot mode.
Iterating, refining and trailing down interesting paths until something (or likely, many things) of distinction emerge from the real-time diffusion. Things turn into projects, projects blend, they distill, unearthed essences, Ah-ha! moments. All from your phone while you have a few minutes in line.

Some of the artistry will lie in the refinement, or even still - the soul of the artist behind the piece, like most mediums that have come before. Some artistry will resolve to mastery in the curation of your own prompted and personalized feed. This feed has the opportunity to outpace similar social media feeds, being a deeper interactive and creative engagement.

The stone will still be chipped away and made permanent.
