My goodness. "Digital Twin" is a just a new 2024 wording for "simulation" but simply placed into a VR environment to allow for seeing a physical representation of the simulation. Unless I missed the clever part, somebody seems to have conned a gov officials into funding a money trough for the simulation software industry. The VR part will help humans visualize the work flow, but finding technical errors and chip yield relies on accurate simulation fidelity, not whether it is in a VR environment. In the simulation world engineers say "garbage in, garbage out" as poor simlations are the norm (very, very common in fact). Let's hope they get some proper experts who are not feeding from the trough to help temper this down.
Change a buzz word and all of a sudden people think some new tech has been born and the world will throw money at it.
For instance a great buzz word is AI. A simple list of earlier tech that is actually the same as AI: neural nets, fuzzy logic, adaptive control, and adaptive Kalman filters. These have been around for over 30-40 years. The only real recent improvement is the number of nodes economically available, with the world mostly ignoring the inexpensive and efficient analog version of neural nets.
