This is a sensible question. Not sure either why the downvotes. I'm curious as to the answer myself. Although, I don't know if we'll ever see sub-nanometer. Maybe that's the reason for the downvotes, that sub-nanometer is not really in the realm of what's possible with current CPU architectures and the physics of silicon. Although, that's simply based on today's physics. Who truly knows what the future will bring.
