A: Good plan. Digital twins will be familiar to anyone in the Internet of Things (IoT) world. They are a digital copy of something physical, say a wind turbine, tunnel, car or airplane. And because this physical thing has been IoT-enabled, it is covered in sensors recording a heap of information, from location to temperature to humidity to performance, to whatever you can and want to measure. Now, if you take the readings of these sensors and apply them to a virtual version of the, let’s say car, you can get an exact idea of the state of the physical item by looking at its digital twin.

Q: Okay, with you so far. Why is this useful?
