Digital Twins
A digital twin is a live virtual model of a physical thing, such as a machine, a factory or a power grid, kept in sync with data from the real one. It lets teams test changes and predict failures without touching the original. For AI it doubles as a training ground, because robots and control systems can practice there safely before they act on real equipment.
