Kasparov I feel was a pioneer in openings study with computers. Kramnik refined Kasparov's methods and was able to outprepare Kasparov as a result. Kasparov did say after losing to Kramnik that his preparation was busted and felt that he had no openings.
I'd say opening study today is influenced by Kasparov's and Kramnik's methods.
Haha, troll much? Like, very?
P.s: I agree, not a big deal with NEGTB in your pocket, pff.
