The assumption is that if an LLM is incapable of playing chess—a game with a relatively small number of pieces, clear and simple rules, and perfect information—even after reading a hundred thousand books on chess, then it is fundamentally incapable of managing an army or a factory. This is because those scenarios involve more 'pieces,' incomplete and fuzzy information, and implicit rules that need to be deduced independently. It doesn't matter whether it has tools or not. It's simply that running tests with chess is cheap, whereas testing with an army or writing a browser from scratch is quite time-consuming and expensive.
