There is a reason why rybka is rated a good 400 points higher than the highest rated gm. Gm's today use engines such as Rybka to prepare for and analyze played games to see what was the best move in every situation, to see what they missed.
When somebody today plays a complicated position right after rybka's suggestion under suspicious circumstances, like for example leaving the table, they get accused of cheating, because making the moves that rybka prefers consistently in complicated positions w/o cheating is not done by anybody. period.
I think it was GM Igor Kurnosov who was accused not to long ago, by super GM Shakriyar Mamedyarov, because he played something like 15 moves in a row exactly as rybka would have played it, under suspicious circumstances.
Fact is, human Gm's are not even expected to find the best moves most of the time, i am ofcourse now talking about the hard positions.
Unless there comes another Nimzovich into the chess world, computers will be unbeatable in, say, a 6 game match.
Also by the part about Nimzovich, i mean that if the way of thinking about chess would change once again, computers would lag behind untill they had enough game material to surpass human player once again.
All this and i havent even mentioned the human factor. I can simply show to the Carlsen vs Radjabov game, Linares 2009. As a norwegian that was a hard day for me, Carlsen blundered away the tournament in the last round when he was in a winning endgame, in a simple position, for a GM atleast, not saying it was for me. AND he had loads of time on his clock.
