The age of the art experience is over. What was once a direct address to the soul today is a way of addressing the statistical aggregate. The blockbuster art exhibit is more significant for its turnstile figures than for the soul-changing moment when art speaks to viewer. New media art matters to the extent it speaks to crowds, and its reality is measurable in the modification of behaviours at the scale of populations.
If (as Stiegler seems to say) personal memory has been replaced by databases, the new unconscious is networked. No longer the tragic history of individual desire and loss, the new social unconscious is the creation of aggregate habit and statistical likelihoods. At its heart is a new void, and the capacities of any new art are dependent on this lack.
