Elon Musk Says 'Chess Will Be Solved' – Chess.com Strikes Back: 10^120 Games, Who's Joking Now?

On February 14, 2026, Elon Musk shook the chess community. On social media platform X, the owner of xAI wrote: "Chess is actually quite easy to solve. There are only 10^44 legal positions. It resembles a puzzle rather than a game. Future AI will solve it within seconds." Less than an hour later, Chess.com's official account responded with humor: "Yeah, but there are 10^120 different chess games. More than the number of atoms in the observable universe." The war of words quickly expanded beyond mathematics, becoming a media duel between a tech billionaire and the world's largest chess platform. I have followed chess for over five decades. People watch Musk make provocations; I watch an entire communications machine in motion. Musk has not dismissed chess only once. In 2026, he wrote: "Chess is too simple for real life. There is no fog of war, no technology tree, no hidden cards, the starting position is symmetrical, and most pieces never move." In 2026, he canceled an internal Tesla chess event just minutes after it began. But this time, his opponent was not an individual player. It was Chess.com — a platform with hundreds of millions of accounts and a communications team capable of responding in multiple languages. At its core, the debate revolves around two different mathematical concepts. Musk cited 10^44 – the maximum number of legal positions that can exist on a chessboard. Chess.com countered with 10^120 – the number of possible chess games, meaning the total number of legal move sequences two players can create from the initial position. Both figures are correct, but they answer different questions. 10^44 describes state-space complexity. 10^120 describes game-tree complexity. And game-tree complexity is precisely what prevents chess from being completely solved. In game theory, a game is considered "solved" when the optimal outcome — win, loss, or draw — can be determined from every legal position, assuming both sides play perfectly. Tic-tac-toe and checkers have been solved in this sense. Chess has not, and will not be solvable with conventional computing power for a very long time. With 10^44 positions, even a supercomputer capable of processing one billion positions per second would need about 10^27 years to traverse the entire state space — roughly 10^17 times the age of the universe. Musk offers a speculative argument: future super-AI will discover information-compression methods far beyond human imagination, thereby solving the entire state space within just a few years. This is a philosophical statement, not a scientific prediction. It resembles saying that humanity will one day find a way to move faster than light: it may happen under a new theory of physics, but no one can bet on it today. What makes this debate truly interesting lies in a detail that has been overlooked. In 2026, Grok 4 – the AI model developed by Musk's own xAI – participated in a chess tournament between AIs and lost to OpenAI's o3. This result is not a secret, but it raises the question: is Musk's dismissal of chess a rhetorical move? If he can convince the public that chess is merely a "puzzle" on the verge of being solved, then Grok 4's loss to o3 becomes a mere incidental setback in a game that is about to become meaningless. This framing resembles a defensive chess position more than a scientific statement. Seven months without major tournaments, seven months of asking why. There is a truth neither side acknowledges: chess has witnessed AI surpassing humans since 2026, when Deep Blue defeated Garry Kasparov. In 2026, AlphaZero went even further, teaching itself to play in just four hours and defeating Stockfish — the strongest engine of that era. Yet chess remains alive. The Candidates still happens. The World Championship final still draws millions of viewers. Chess.com still sets records for online players during every Champions Chess Tour. Why does chess survive? Because people do not play chess to find the best move. People play chess to experience the process of thinking, to face time pressure, to read opponents' intentions, and to bear responsibility for every decision. Computers may calculate more accurately, but computers cannot know the thrill of a queen sacrifice. Computers do not know the feeling of victory after six hours of battle with the clock about to fall. The value of chess lies in human experience, not in mathematical difficulty. Patience is not stillness. Patience is waiting for the right moment of an opponent's press. Chess.com seems to understand this very well. Instead of engaging in academic debate, their communications team chose to respond with humor, even using Vietnamese to reply: "Do kỹ năng thôi" — a message that can be read on two levels: either complimenting Vietnamese chess players, or slyly dismissing Musk's chess judgment. This strategy shows that Chess.com is not merely a tech company but a brand with personality, capable of turning an attack into a media opportunity. I am sixty-nine years old. I still learn from young people. Chess does not retire. And perhaps that is what Musk does not understand — or deliberately refuses to understand. Chess does not need to be "hard to solve" to be valuable. A game gains value from what it gives its players, not from its computational complexity. When Musk calls chess "easy to solve," he confuses two entirely different questions: whether a machine can calculate the optimal result, and whether a human being finds the game worth playing. The answer to the first question does not affect the answer to the second. The quarrel between Musk and Chess.com may soon be forgotten. But it leaves an important message for the entire chess ecosystem: in the AI era, defending the humanistic value of chess — creativity, character, patience, and even human error — will be a more important task than ever. AI may solve the chess problem. But AI cannot solve the puzzle of why a child still sits for hours before a chessboard, despite knowing that a cheap phone can defeat them. In the end, the most remarkable thing is not 10^44 or 10^120. What is remarkable is that a tech billionaire spent time debating a game he claims is "on the verge of being solved." If chess were truly meaningless, why would Musk bother? Perhaps, even he acknowledges that chess conceals something that money and AI cannot buy. And when the world's richest man tries to deny the value of something, that is often the clearest signal that the thing matters far more than he is willing to admit.
