I'll propose a purely information-theory and somewhat mechanical answer to this issue.
As the art is effected through the exposure to information (which will hopefully fire some unused synapses and modify the future behaviour of its customers,) the real change with the networked society is that the noise floor of the information intake is going up. Until up to few decades ago, information feed was mostly a matter of choice - one would go to the church, read a book, watch something on the screen, peep through the hole, etc. Today the choice is mostly about which information gets stopped - our decision efforts are about what we don't want to find out - we are burning brain cycles not for seeking but for defense. Getting less shit is considered to be a success. There are few resources left for finding gems. It's like wartime - you are lucky to find uncontaminated food and bullet-proof shelter, there is no time for chefs and architects. Unlike regular war where most eventually get pissed at the carnage, it is not clear that there is a viable opposition to the information carpet bombing. It is clear, however, that while it's going on you can forget about art. end (of original message) Y-a*h*o-o (yes, they scan for this) spam follows: <...> # distributed via <nettime>: no commercial use without permission # <nettime> is a moderated mailing list for net criticism, # collaborative text filtering and cultural politics of the nets # more info: [EMAIL PROTECTED] and "info nettime-l" in the msg body # archive: http://www.nettime.org contact: [EMAIL PROTECTED]
