Inspired by M. Jahi Chappell (title above), Ivan Illich (relationship of energy consumption, social/economic inequality, and specialization) and Joseph Tainter (quote below). Needless to say the arts are subject to the same law of declining marginal returns. Also note that there is immense energy consumption involved in administrators maintaining the social coercion necessary for institutional buy in from the administered.
Whereas art has become as obscure and reliant on specialist knowledge and infrastructure as physics, aesthetics is more akin to ecology, based more in an experiential and observation based rubric.
Obviously, this applies to art as well:
Myself I cannot see the persistence of the artist type. I see no need for the individual man of genius in such an order. I see no need for martyrs. I see no need for vicarious atonement. I see no need for the fierce preservation of beauty on the part of a few. Beauty and Truth do not need defenders, nor even expounders. No one will ever have a lien on Beauty and Truth; they are creations in which all participate. They need only to be apprehended; they exist externally. Certainly, when we think of the conflicts and schisms which occur in the realm of art, we know that they do not proceed out of love of Beauty or Truth. Ego worship is the one and only cause of dissension, in art as in other realms. The artist is never defending art, but simply his own petty conception of art. Art is as deep and high and wide as the universe. There is nothing but art, if you look at it properly. It is almost banal to say so yet it needs to be stressed continually: all is creation, all is change, all is flux, all is metamorphosis.
