The thing is, a UI is a combination of far too many personal tastes and habits and a GUI multi-dimensionally more so. It's like a marble slab that needs a Michelangelo to turn it into an image.
We've had one Michelangelo and a Rodin and only a few Greek sculptors in the past, what, three thousand years? Do we really think that a near infinite number of monkeys is now going to solve that problem, specially when the marble slab is undergoing its own metamorphosis underfoot? Good luck! Lucio.
