Alan Turing was many things (genius, spy, homosexual), but I think nobody would call him a duck.
I don't think talking about conciousness is relevant. Anything that looks like it has conciousness is enough. I can only be sure about my conciousness. I think the Duck test applies here well.
Ahh. teh illiterateness of me.
Anyhoo, I didn't call him a duck, I called the computer a duck. Even Wiki has an article about this whole conciousness, can we forget the question of "can machines think" thing already?
