How does anything I said imply they are "all idiots". Quite the opposite, the other guy's argument demonstrates that they had zero need to go to a new process because they were going to do well regardless.
nvidia is currently selling very low power control boards for robotics, computer vision, drones, cars, etc, built on 12nm. There simply was no compelling reason for them to have a higher BoM to go smaller, and they had proven existing designs. There is a world of excess 10nm fab capacity, and you can sign up for 7nm all day long. Nope. Because what random blowhards say on HN has little correlation with fact.
