The Copenhagen interpretation of quantum mechanics postulates that "atoms form a world of potentials and possibilities, rather than of things and facts". Following a parallel path Ajahn Sumedho , a teacher from the Thai Forest Buddhist tradition , has proposed that: We do not know the future. But we do not need to know. We can let the future be the mysterious unknown, the infinite potential - the possibility for pleasure, the possibility for pain, the possibility for peace. As we let go of the fear of the unknown, we find peace. My photo of a stormy sky over Colombo in Sri Lanka hints at that infinite potential. There are many ways to experience it, and music is one of them. For me two examples particularly relevant to this post are Claude Vivier's Siddhartha and Jonathan Harvey's Body Mandala . It is now time for me to defy my advancing years and travel into the mysterious unknown of the future. Which means On An Overgrown Path will fall silent, When, or indeed i

With regard to the main question, I picture most people listening to the computer playing the Goldberg out of curiosity and then moving on. If it did indeed play the work like Gould, the point would escape me altogether, though they did well to constantly invoke Gould's name, for his obsession with the perfect recording suggests one performance fixed in time, which I take it is what the computer 'performance' would also be.
That brings to mind those artists -- Curzon, Serkin, et al. -- who had to be dragged to the studio, or Celibidache, who wouldn't record in a studio at all, because the idea of a fixed performance was alien to them. And so, we have fixed performances from Gould and a computer, but I think there are few of us who would not turn to Perahia, Hewitt, Tureck et al. for greatly varied performances, and the concert hall where inspiration of the moment (notable with Arrau, Cherkassky, though I'm straying from the Goldberg again here) may make for magic moments.
So, no, we don't NEED genius robots. But I was delighted that your blog was mentioned and given due credit in the discussion, Bob, and in tones of such well-deserved respect.
