How many of these have you actually observed happening? Because your assertions that they are "silent" (in the sense of the original piece) seems wildly out of line with what I've seen. You might try watching the documentary I linked to see how you're wrong about recorded music, for example. And if if your only experience of product development is that sort of top-down drudgery, I'm truly sorry, but it absolutely can be richly creative and collaborative.

That you're blaming your failures on me is not a good sign, so this is probably my last reply. I also mentioned improvisational music and movies. I could also add staged theater, in which much of the creative work happens in group contexts (starting with table readings, going through all of the rehearsals, and often after).
