Unless we can agree on an objective meaning of “important” I’d say definitionally that you’re right and wrong?

This AI production is probably “important”, being the first AFAIK to win an art competition.

If AI creates some art - let’s say a painting -depicting the death of the last human, if it were to do that, and broadcasts it across the universe and carves it into each new world it visits, that would certainly meet my criteria for an “important” work.
