It is not necessarily the case, as the NTY infers, that Kasparov's game was hindered by the use of the computer. Another possible inference is that Topalov and Anand get along better with their computers than Kasparov and Karpov, even if Kasparov and Karpov are helped and not hindered by theirs. After all, Topalov and Anand are much younger than the two K's.
