The 10^120 and the Social Media Showdown: When Elon Musk Defeated Himself in a Game with No Winner

On an April afternoon, while most of the chess world was following Gukesh D's games and the tense rounds at the Candidates Tournament, a debate unfolding on platform X drew millions of eyes — not because of a brilliant move, but because of a number: 10^120. Elon Musk, the man who once cancelled a Tesla chess event in 2026 because he thought chess was too simple, had tweeted: "Chess will be solved by AI far stronger than anything that exists today." Chess.com, with an account operated by people Musk called "interns," fired back with a simple tweet: "Just skill." This exchange, happening in the virtual space of social media, turned out to be one of the most notable games of the year — not because someone won, but because it exposed a paradox the entire chess world is facing. To understand this debate, one must first understand what the number 10^120 means. In game theory, there is a distinction between state-space complexity — the number of legal positions that can appear on a board — and game-tree complexity — the number of possible move sequences from the starting position. For chess, the number of legal positions is estimated at approximately 10^44, while the number of possible move sequences reaches 10^120. For comparison, the number of atoms in the observable universe is only about 10^80. Chess.com, in a tweet praised for its accuracy, used the 10^120 figure as evidence that chess cannot be "solved" — meaning determining the optimal outcome from every possible position — using current computational methods. Musk, with logic that somewhat oversimplified, argued that 10^44 is still a "small" number and that future AI would find ways to compress information to solve chess. The truth is, chess has been proven to be completely unsolvable in the strict mathematical sense. Checkers, with approximately 10^31 positions, took decades of computation and a generation of supercomputers to solve. Chess, with 10^44 legal positions, requires computing power far beyond any resources existing or foreseeable in the near future. This is not an absolute limit claim — mathematics never says "never" — but a practical assessment of the gap between ambition and capability. However, Musk is not the first to hold this view. In 2026, when Deep Blue had defeated Kasparov for ten years, World Champion Viswanathan Anand remarked that chess would never be completely solved due to its complexity. Nearly two decades later, that prediction still stands. But the debate is not merely about mathematics. It reflects fundamentally different perspectives on chess's meaning in the AI age. Musk, as the founder of xAI and one of the most influential figures in technology, positions himself as a forward-thinker — someone who sees ahead to the ability to overcome any computational barrier. His view, though technically somewhat oversimplified, reflects a common belief in the tech world: everything will ultimately be solved by artificial intelligence. For Musk, chess is a problem, and every problem has a solution. Chess.com, as the world's largest chess platform with over 150 million users, has legitimate reasons to defend chess's image as a game of infinite depth. If the public believes chess is "simple" or will soon be completely solved by AI, the perceived value of the game — and consequently, Chess.com's brand value — could be affected. Chess.com's response in this debate was a lesson in social media marketing. Instead of writing a lengthy analysis of game theory, they chose short, witty, and somewhat provocative answers. "Just skill" — a phrase carrying the playful tone of a chess player, implying that Musk lost not because chess is simple but because his skills weren't sufficient. The use of Vietnamese in some tweets was also noteworthy, showing that Chess.com was targeting a multinational user community, where Vietnam is an important market with millions of chess players. This strategy was so effective that the debate attracted millions of views, creating an outreach that Chess.com could hardly have bought through traditional advertising. What this debate exposed, however, was not just a PR battle between a tech billionaire and a chess platform. It reflected a deeper shift in how the world perceives chess. From a mental sport considered the pinnacle of strategic thinking, chess has become a tool for measuring AI capability — a "benchmark test" that tech companies use to compare their products. The 2026 AI tournament, where xAI's Grok 4 lost to OpenAI's o3, was clear evidence of this trend. When AI companies compete to demonstrate their superiority through chess ability, chess is no longer just a human game — it has become a battlefield for machines. This shift brings both opportunities and risks for the chess ecosystem. Positively, tech-world attention helps chess maintain visibility in an era when human attention is scattered across countless entertainment platforms. When an influencer like Musk tweets about chess, millions of people — many of whom may never play chess — immediately realize the game still exists and matters. Negatively, when chess is associated with images of being "simple" or "will be solved," it may lose its standing as a genuine intellectual challenge. This affects not only the game's image but could also impact corporate sponsorship decisions and media interest. A blind spot in the debate that both sides overlooked: chess, like many sports and arts, does not exist because of its "unsolvability." Humans don't play chess to prove they're smarter than machines — they play for the joy of the thinking process, the tension of time scrambles, the pride of finding a beautiful idea, the frustration and learning from mistakes. Magnus Carlsen is not a chess ambassador because he's stronger than Stockfish — he's an ambassador because of how he plays, how he thinks about chess, how he inspires millions watching every game. When stadiums were empty during COVID years, I learned that applause is not just a reward for brilliant moves — it's how humans connect through the game. And that is something no algorithm can replace. Returning to the debate: who won? Technically, Chess.com provided more accurate figures. In terms of media, Chess.com gained significant outreach and community goodwill. In terms of reputation, Musk may have put himself in a difficult position when a chess platform "taught him a lesson" before millions of followers. But the right question is not "who won" — it's "has chess won yet?" And the answer, as always in the chess world, still needs more time to know. But one thing is certain: as long as humans still sit across from each other at a chessboard, as long as they still feel their hearts race when their opponent thinks, as long as they still smile after a well-played game even in defeat — chess will never truly be solved. Because the essence of chess does not lie in the number 10^120 or 10^44, but in the moment of silence before a puzzling move — the moment when both players don't know what will happen, and it is precisely that uncertainty that makes them come back.
