Kurros and Aleph,
Yes, I agree it is being creative. Alpeha, you said that my idea of creativity was vague but to me, that is what creativity is, vague. Otherwise, everyone would be creative using a formula. And this computer is using formulas.
In game one, the computer started off conservatively probably because it's human competitor started off conservatively. It is simply mirroring. At least in the beginning. That is a sort of formula. So when you say it is being creative, I think it is using creative formulas.
Maybe it can switch formulas easily like a boxer who switches from fighting right handed to left handed with ease. It can be that a computer is more flexible, does not get stuck in a mindset.
But in order to be that free, I feel that it can not be conscious. Maybe that is what hurts humans: consciousness. Concentration is taken away by being conscious of the overall pattern of game. A computer, on the other hand, move 54 might as well be move one. Past moves are not distracting it.
