I also think art can include things like being a chef, barista, baker, barber, and brewer, distiller, wine maker; not just the things we typically call art. Things that are in more demand than paintings.
Except all those jobs are going away with the automation revolution. You can't have an economy based off the equivalent of getting carriage rides in central park where its just a frivolous humor to experience human powered food production or a haircut done by a barber.
Don't think automation will get rid of these jobs - have you seen the cronut? Don't think a computer would have been able to derive that creation... (not sarcastic)
Also, as we create more time, we'll have to spend it on these luxurious that currently seem frivolous.
