That's a curious use of an already established term, "Digital Twin"[0]. A digital twin is a virtual model designed to accurately reflect a physical object.
Link me? I'm not sure what you're referencing. For what it's worth, the concept and model of the digital twin that I referenced was first publicly introduced in 2002 by Michael Grieves, at a Society of Manufacturing Engineers conference in Troy, Michigan.
