Thing is, fab building, integrating production machinery, fab supply chain, and operations still has a lot of special sauce in it. Some of those factors are not affected by transistor physics converging at a limit. But, for less than cutting-edge chips, if your budget is a bit more than for printing on paper, it's getting there.
