Distraction is the permanent end state of the perfected consumer, not least because distraction is a state that is eminently programmable. To buy a guitar is to open possibilities.

It brings the corporation’s focus on quantitative performance indicators to the domain of music, displacing the usual mode of subjective enjoyment."
