This reminds me of Wilde's preface to Dorian Gray

The nineteenth century dislike of realism is the rage of Caliban seeing his own face in a glass.

The nineteenth century dislike of romanticism is the rage of Caliban not seeing his own face in a glass. The moral life of man forms part of the subject-matter of the artist, but the morality of art consists in the perfect use of an imperfect medium. [...]

Those who read the symbol do so at their peril. It is the spectator, and not life, that art really mirrors. Diversity of opinion about a work of art shows that the work is new, complex, and vital. When critics disagree, the artist is in accord with himself. We can forgive a man for making a useful thing as long as he does not admire it. The only excuse for making a useless thing is that one admires it intensely.

All art is quite useless.
More on this from me and Weinberger

I thought that Ballmer's quote that "There's no innovation that we've seen come out of at least Linux," was quite... uh... stirring.
