Let's make my point more clear.
The old paradigma (and the only one existing at the current moment) was the one in which programs had to learn how to play chess stronger than humans. The main part of the labours was directed to that goal (to beat humans) -- and now after decades of attempts as well, it is achieved. At the road to that target the programmers achieved much. Their achievements are undisputable. The programs play stronger than humans.
And now? Now what? In my view now Computer Chess is lacking the goal of worth. What is the current goal of the computer chess? The program that will play stronger than Rybka? Yes, the noble goal, of course, but that goal cannot be sufficient for the new stage of development, for a newer, higher set of the development' spiral. Such a goal can not give a sufficient enough reason of existing of Computer Chess, IMO.
I think that the future degree of development must be found in the exploitation of the new main goal of the computer chess. This has to be the phase of development in which the main goal will be a no which program or engine will reach #1 spot, but which program will manage to effect the human's fashion of game, which progarm will succeed in immitation /and may be re-creation/ of human thinking at the chess board.
So, from my point of view, things returns to the beginning /Turing, Botvinnik/, but already -- enriched by the accomplishments of the old paradigma. The new capital goal, according to me, has to be that the programs will start to play chess the way human play it. This must be the new challenge to the programmers, not who's program will be the #1 in the rating lists of SSDF, CCRL or CEGT.
Sorry for my bad english. I hope that you'll understand what I wanted to say
