Maybe you're right, but I hope not. Percentage of draws between top grandmaters has always been on an increasing course. Nowadays 2 out of 3 games are ended in a draw. It is natural then, to predict that in 50 or 100 years something like 4 out of 5 games will end in a draw, and it could very well happen that in a little over a century almost all the games between top grandmasters end in a draw. But that will not mean that the game is solved, since the draw is the result of strength and knowledge of the two players, not because they *know* what to play to reach a draw. You can call a game "solved", if everyone can learn what to do in a short time, and will then, play the optimal moves forever (like tic-tac-toe). For computers, "solved" will mean that they have a database or heuristic to determine the optimal move at every position. For example, Shaeffer and his research group at the University of Alberta are close to "solving" the game of checkers, in form of having a database of win/lose/draw for every possible position. And according to this definition, the game of chess can NEVER EVER be solved.
