I think the proper formulation of the argument is whether Deep Blue seemed-to-understand chess better than Kasparov seemed-to-understand chess. "Understanding" will turn out to be simply a compression with optimization toward survival of the compressing algorithm. When "survival" finally resolves into a conflict between different algorithms, the winner will be that compression algorithm which compresses those that cannot compress themselves.
