The concept of the digital twin contains a trap. When we think of a twin, we think of a copy of an individual. In the digital world, we often think of a copy of an individual device – a physical replica of conveyor belt or radar. The trap is that we limit the scope of twindom and think too small.
This concept of digital twins in the manufacturing world should not be confused with the concept of human digital twins.
