The point is not that "postmodernity has no cultural or intellectual value". Indeed, even a generator as exemplified in the article can be said to have such value. Since the end of the XIXth century it has become clear, albeit conveniently ignored, that the value of interest is crucially practical. Hic rhodus, hic salta. When it's not, aside from bringing some short-lived distraction, as any other consumption, it validates and reinforces a status quo that, judging by the state of the world, is not conducive to common happiness or productivity. To say the least.
