@text = "Many take this change in value a step further, giving their passivity a positive veneer. They romanticize the self-destructive artist who loses control of him-or herself. Anything that smacks of discipline or effort seems fussy and passé: what matters is the feeling behind the artwork, and any hint of craftsmanship or work violates this principle. They come to accept things that are made cheaply and quickly. The idea that they might have to expend much effort to get what they want has been eroded by the proliferation of devices that do so much of the work for them, fostering the idea that they deserve all of this—that it is their inherent right to have and to consume what they want. “Why bother working for years to attain mastery when we can have so much power with very little effort? Technology will solve everything.” This passivity has even assumed a moral stance: “mastery and power are evil; they are the domain of patriarchal elites who oppress us; power is inherently bad; better to opt out of the system altogether,” or at least make it look that way."
