I am just wondering if this is the normal meaning of "digital twin"? I saw that terminology used in some other contexts as a term of art, like where nvidia showed digital factories that are kept in sync with real factories. Is an AI model trained on something considered as that thing's digital twin now? It's OK with me if it's true, I'm just trying to keep up with what things are called.
