As awareness of digital twins grows, so does its definition, as well as its warnings, but so does its results. We're right here in the middle between pre-hype and post-hype:
Digital twins of the Earth: Researchers are critical of the term
Dec 2024, phys.org
FYI - The Destination Earth project was launched in 2022 as a key pillar of the European Commission's efforts towards the Green Deal, and wants a digital simulation of the Earth. The German Federal Agency for Carthography and Geodesy is working on a digital, intelligent 3D image of Germany and the German federal state of Rhineland-Palatinate is running a digital "hydro-twin" project.
These scientists are trying to add to the conversation:
They point out the lack of a clear definition of the term "digital twin of the Earth," which may be misleading. "All digital representations of our planet are model representations. As such, they will always be detached from reality—as a map can never fully replicate the land it depicts" and "suggests that we can create a digital representation that allows us to stress-test the structural properties of the Earth system with any desired degree of accuracy and precision" and as that is not the case, "as every model is a simplification of reality, and its creation requires simplifying assumptions that will unavoidably lead to uncertainties." Also, "the creation of new models with higher resolutions will not necessarily lead to an improvement in knowledge and results; and new complex models need new methodologies that will enable researchers to apply them."

Digital twin research finds colon cancer cells can be reverted to normal cells

Results already, so we're in the next phase of the digital twin hype, where it's not hype anymore.
