This makes little sense. It's funny to see that capitalist aping of artistic practice is now being regarded as a new era in artistic practice by this guy though.
Art has had a fascinating relationship to capital well before capitalism, but to confuse its continuing ability to survive with some kind of fundamental transformation of the practice is kinda silly.
Yes, okay: what is art?
The answer isn't: commerce. No need to go so far back, but just look to cave paintings to discover that these ideas of economy and capital are only sidelines and contextual footnotes to the practice of art.
