How clear is the distinction between knowledge and intelligence really? The whole genius of the digitial computer is that programs are data. When a human observes someone else doing something, they can copy that action: data seems like programs there too.

And yet "cognitive" is listed as several levels above "knowledge" in the above post, and yesterday CYC was mocked as being not much better than a dictionary. Maybe cognition and knowledge are not so separate, but two perspectives on the same thing.
