Personally, I rather look forward to a computer program winning the world chess championship. Humanity needs a lesson in humility.
Succeeding is not really a life experience that does that much good. Failing is a much more sobering and enlightening experience.
Often times, music is used to evoke an emotion and it's become a cliche, so I don't want to do that, and actually what I do, is that emotional intensity that has developed throughout the film, I allow it to get released by having that music at the end with the credits.
