Elon Musk claims AI will solve chess: Chess.com responds with a 10^120 universe

The moment began with an innocuous tweet from a tech billionaire. Elon Musk – founder of Tesla, SpaceX and xAI – sitting in front of his screen, typed on social network X: “Chess will be solved within a few years.” No research attached, no evidence. Just a statement in the style of someone who has changed the world many times. But for the chess community, it was not prophecy – it was a declaration of war. Chess.com, the world's largest online chess platform, needed only seven minutes to respond. Their official account wrote: “The observable universe has about 10^80 atoms. Meanwhile, a single chess game can unfold in about 10^120 possible ways. Musk, are you sure it will be ‘solved’? Or is it ‘Do kỹ năng thôi’?” The phrase “Do kỹ năng thôi” was written in Vietnamese – an interesting detail showing Chess.com knows their audience goes beyond Silicon Valley. This writer – who has spent 40 years observing chess in India and Vietnam – could not help but laugh. The way an outsider to chess declares he can solve a game that has existed for over 1,500 years, and the way the chess community replies with numbers and humour, recalls the human-machine clashes of the 1990s. But something deeper is happening. Musk once said in 2026: “Chess is too simple for real life because it has no fog of war, no technology tree, and both sides have symmetrical starting positions.” Perhaps that is why he did not hesitate to call Chess.com's move a “reaction of an intern.” But those watching this match can see: Musk struck first, and the defender still stands. So, just how complex is the board Musk wants to solve? The number of possible chess games – called game-tree complexity – is 10^120. If all atoms in the observable universe (about 10^80) each became a supercomputer, you still couldn't list every possible game. The number of legal positions is often cited as 10^44. That number exceeds the computational capacity of any existing machine, even with the smartest algorithms. To “solve” a game completely, one must prove from every legal position that the optimal outcome is win, loss or draw, assuming both sides play perfectly. Checkers – a game with over 10^20 positions – required a nearly two-decade computer project, concluded in 2026, to solve. Chess has 10^44 positions – billions of times larger than checkers. No supercomputer, no matter how powerful under current physical laws, can handle that within a few years. But what makes the Musk–Chess.com battle remarkable is not only mathematics. It is the story of how we perceive human intelligence in the age of AI. In a recent AI Benchmark project, models like xAI's Grok 4 and OpenAI's o3 competed in their own chess tournaments. Result: Grok 4 – Musk's model – lost to o3. This explains why Musk so quickly attacked the very game his system has not yet won. It is a clever “goalpost shift” of a losing player: if you can't win under current rules, convince your opponent the rules are destined to be abolished. This is exactly where Musk's supposedly threatening move reveals his weakness. When a person cannot prove something technically, they often appeal to the future. Chess.com's reply – with gentle sarcasm – highlighted a flaw: if AI is smart enough to solve chess, why can't it find a better algorithm to play chess right now? Yet, from an outsider's perspective, this writer sees a risk no one is talking about. In this debate, both parties benefit: Musk reinforces his narrative of an omniscient AI future; Chess.com gets huge media attention. But the broader chess community – and chess lovers in particular – might face a long-term consequence: if the public begins to believe chess will be “killed”, will they still want to learn? Will sponsors still attach their names to human players? When I was a commentator for chess tournaments in Da Nang, I often told audiences about immortal games between humans and AI. Someone once asked me: “Why do humans need to play chess when computers have been stronger than us since 2026?” My answer was not about numbers. Chess is a dialogue with oneself. Each game is not just a battle between two colours, but a battle between will and fatigue, between hope and fear. Machines have no fear. That is why they will never understand why a player cries after winning, or why a drawn position can be achingly beautiful. Looking at the Musk–Chess.com clash, I am reminded of a sentence I once wrote: “I thought I was exiled from football, but football led me deeper into myself.” With chess, I feel something similar. The deeper we dig into numbers and algorithms, the closer we come to an un-solvable mystery: the creativity of the mind that created this game. So, is Musk right? Mathematically, the answer is no – at least not for decades. But philosophically, he may be right in an unexpected way: if AI solves chess, humans will keep inventing newer, more complex games – as we have for 1,500 years. What AI cannot solve is humanity's drive to conquer. That is not on any board. But the real question for us – chess lovers – is not whether AI can solve chess. It is: When AI answers everything, will humans still ask the right questions? For me, chess is never just a game. It is a mirror. Like any mirror, it reflects only what we bring before it. Musk brings technological arrogance. Chess.com brings communal intelligence. And I – a writer from Vietnam – bring the belief that even if every game is solved by a computer, humans will still sit down, set up the pieces, and begin a dialogue with themselves. Because no algorithm can calculate the smile of a child delivering their first checkmate. Let the 10^120 game unfold. Let AI keep learning from the games we create. But never forget that the one who moves the pieces – whether in Silicon Valley or on a street corner in Da Nang – is always human. And that, perhaps, is the best news for the future of the world's oldest intellectual sport.
