If I'm honest though I don't really care about what will happen in 100 years time - the future will take care of itself, whatever I think. Human culture, like evolution and climate, is probably governed by the the laws of chaos and anything could happen.

Up to a point - yes - but our thoughts and actions and philosophies in the here and now are bound to have some influence on the future. And of course it won't matter to any of us a hundred years hence - but it might matter to some of us in, say, twenty or thirty years hence.

I've always thought of music making - like any art form - as an evolutionary process, regardless of the musical genre in question. Jazz evolved and continues to do so, with all styles sitting side by side. Blues evolves, with new music incorporating and extending the old forms - think of performers like Little Axe or Pig In A Can - and does so without debasing or "occupying" the music. Is folk music alone and apart from this natural evolution - bereft of creativity? If so, then why? If not, then how?

My original question, I guess, will stay unanswered...
