As the advent of advanced technology makes labor unnecessary for advanced intelligences, one aspect of human life that will gain increased rather than decreased importance is art.
By "art" I don't mean specifically the creation of paintings, drawing, plays, symphonies, dances, novels and so forth -- these are great, but they're just particular examples.
I mean the creation and sharing of new patterns purely for the sake of having these patterns appreciated by one's own mind and others' minds.
Once the need for humans and other advanced intelligences to labor for sustenance is eliminated, what will be left for minds to do is precisely to create and appreciate art.
"Art" may involve building baby universes or new AI systems or 9-dimensional meta-multiversal movies ... or scientific data-sets or theories or mathematical theorems ... or perfecting one's own array of mind-states ... or drawing pictures of trees on paper ... all of the above and many more!
(Let infinity flowers bloom...!)
The point is not the particular medium but rather the motivation. For example: Now people do science in part because they get paid for it, in part out of a desire to help in the process of creating new technologies to make peoples' lives better, and in part out of a desire to understand and create beautiful knowledge. Once scarcity and suffering are largely palliated, only the last motive -- which is essentially artistic -- will remain.
The artists shall inherit the Cosmos.
