Quantum entanglement is a beautiful trick, but it doesn’t give us a faster‑than‑light messenger to sync VR. The entangled pair shares correlations instantaneously, but you still need classical communication to coordinate actions, so causality stays safe. Think of it like two dice that always match; you still have to roll them in the same place to use the result. So, it won’t wipe out lag, just adds a curious layer of bookkeeping.
