Can AI actually design a usable PCB? A case study of the WatcheRobot control board

A developer uses the control board inside WatcheRobot as an example to ask whether AI can go beyond generating schematics and complete component placement and routing, and make the assembled board actually work. He would rather hear from people who have used AI to design a PCB and then actually had it fabricated and tested, including what AI got right and what still needed manual correction, rather than see another good-looking generated layout.
