The design optimization software for modern semiconductors is arguably the most advanced design software on earth with likely tens if not hundreds of millions of man-years put into it. It takes into account not only the complex physics that apply at the nano-scale but also the interplay of the various manufacturing steps and optimizes trillions of features. Every process change brings about new potential optimizations, so rather than compensating for bigger nodes it actually widens the gap further. By analogy, the jump from hatchet to scalpel in the hands a layman is far less than the jump from hatchet to scalpel for a skilled surgeon.
