The 'Ship of Theseus' meme originated from the series finale of Marvel’s WandaVision, where Vision and his reconstructed counterpart, White Vision, engage in a philosophical debate rather than a physical fight. They discuss the ancient Greek paradox regarding whether an object that has had all its components replaced remains fundamentally the same. The scene became an instant internet sensation for its unexpected high-brow intellectualism in a superhero setting. Online, it is used to humorously describe situations involving identity crises, software refactoring, band member replacements, or any scenario where a person or thing has undergone so many changes it might be entirely different from its original form.
