Google is working with AI to digitise cable networks

Electricity is the energy that drives modern society but trying to figure out where cables are located continues to provide engineers with major challenges when considering that these cables were installed decades ago. Now, Google is using AI to automatically generate maps of where all cables are so that future engineers know precisely how to make upgrades and repairs. Why are cable networks providing engineers with significant challenges, what will Google's new project do, and should this idea of digitised cables be brought into homes? If there is one fact of life that I am truly grateful is that electricity comes out of my sockets whenever I require it. Just like the Armstrong and Miller Time Traveller sketch, the number of people in society who are entirely oblivious to the effort and resources needed to correctly operate a nationwide grid is astonishing (electricity is that thing that comes out of the wall).
