Again, building an opening book does not take place at move decision time. Aside from that, there are several optimization techniques that you can apply to choose the hyperparameters appropriately, but once again, this has nothing to do with cyborg chess.
From my perspective, cyborg chess is about playing the best game of chess in all time... only stopping once we have discovered "the perfect game" (aka: proving that White-wins, Black-wins, or a Draw is always possible with perfect play)
The computers currently playing Chess, and Go, are incredibly powerful. But they are far from perfect. People have constantly found weaknesses in chess playing programs over the past 20 years, and as a result, have improved chess programs significantly.
Go has only had 2-years in its "cyborg" state, where we can finally use computers as a methodology of exploring the game state.
Solving Go is an interesting theoretical pastime, but there is no reason to expect any particular overlap between people who are interested in playing the game (like Lee Sedol) and people who are interested in building machines to asymptotically approach a solution beyond human understanding.
Most of the resistance you're getting in this thread seems to be due to the fact that you think people who are interested in the game should also be interested in the other thing, and it just seems that a lot of them aren't (including Lee Sedol).
Playing Go challenges your mind with vast complexity and immediate feedback of winning or losing every game. It's a deeply engaging hobby for people who are susceptible to that kind of thing, and it used to be a meaningful career, with competitions, schools, and professional teachers. All of that changes now that software is vastly better at it than any human can ever be. The rush of competing by the strength of the moves you understand and make, by the unaided strength of your own mind, cannot be compared to picking between different engines to make moves for you based on some heuristics about which engine is better at openings. The era of human Go is simply over, for better or worse.
Claiming that the era of human Go is over seems melodramatic. Computers were better than the best humans at chess decades ago and professional (human) chess is still big, with schools, tournaments, prize money, superstars (Magnus Carlsen is a pretty big deal) etc.
