> 3D transistors already expanded the limit of how small parts can get before physics hits you in the face with a baseball bat. Yes, but we are just starting 10nm now. Go two more nodes (if I understand correctly that is meant here by cycles) and you are at 5nm. https://en.wikipedia.org/wiki/5_nanometer https://en.wikipedia.org/wiki/5_nanometer to put that into perspective: "An Australian team announced that they fabricated a single functional transistor out of 7 atoms that measured 4 nm in length." Maybe we can make our way down to single atom transistors eventually, but who knows how long it will take to make that commercially viable.
